Best Motorcycle Luggage Rack Bag

Best Motorcycle Luggage Rack Bag for Touring and Daily Rides

A strong motorcycle luggage rack bag keeps cargo secure, offers useful capacity for your ride, and fits your motorcycle’s rear rack or trunk; touring riders and commuters need different combinations of those features. This roundup compares 10 options ranging from a compact 13-liter bag to a 73.5-liter tour trunk bag. Expandable designs add flexibility, while included rain covers, straps, and separate pockets can make loading and weather protection more convenient.

Fit deserves special attention: some bags are aimed at touring models, and one explicitly has motorcycle exclusions. Check your bike and mounting setup before choosing.

Our leading pick balances 33–45 liters of expandable storage with a reinforced frame, non-slip base, rain resistance, and sissy bar straps.

The Rhinowalk 33–45L Tail Bag is the best overall choice in this lineup because it combines useful expandable capacity with a reinforced frame, a non-slip, wear-resistant base, and sissy bar straps. Its rain-resistant design and included helmet rain cover suit riders carrying varied luggage in changeable weather. If you need substantially more room for touring, consider the Nelson Rigg NR-300 Route 1 Traveler, which lists 73.5 liters and mounts to many tour trunk racks.

Detailed Reviews: Best Motorcycle Luggage Rack Bag

Rhinowalk 33–45L Tail Bag

#1 · Best Overall

1. Rhinowalk 33–45L Tail Bag

  • Capacity: 45 liters
  • Material: Polyvinyl Chloride (PVC)
  • Compatible with Vehicle Type: Motorcycle

Best for: Expandable all-weather touring storage.

Why it ranks #1: Its 33–45L expansion, reinforced steel-wire and PE-board frame, non-slip base, rain resistance, and sissy bar straps make it a versatile rack-bag choice.

A double-sided expansion zipper takes the Rhinowalk from about 33L to 45L, giving riders a way to add room for longer trips without starting with the bag at its largest size. Its reinforced frame and rain protection support packed luggage on motorcycle journeys.

The reinforced steel-wire frame and PE board help the bag retain stability, while the anti-slip, wear-resistant bottom supports contact with a rack. Open the double-sided zipper to increase capacity from about 33L to 45L for extra clothing or a helmet; the listed contents also include sleeping bags, laptops, gloves, and cameras. Rain resistance and the included helmet rain cover help protect luggage in wet conditions, and sissy bar straps offer another mounting option.

Pros
  • Expands from about 33L to 45L
  • Reinforced steel-wire frame and PE board support stability
  • Anti-slip, wear-resistant bottom
  • Rain protection and helmet rain cover are included
Cons
  • The listed maximum capacity is 45L, below the 60L offered by the Rhinowalk MT4060-1.

Skip it if you need more than 45L of stated capacity; the Rhinowalk MT4060-1 expands to 60L for larger loads.

Choose this Rhinowalk for motorcycle trips where adjustable 33–45L capacity, rain protection, and a reinforced structure suit the load. Its stated maximum is 45L, so riders carrying more should consider a larger-capacity option.

Nelson Rigg NR-300 Traveler

#2 · Highest Capacity

2. Nelson Rigg NR-300 Traveler

  • Capacity: 73.5 liters
  • Material: UltraMax Fabric
  • Compatible with Vehicle Type: street cruiser motorcycles, street sport…

Best for: Large touring trunk-rack loads.

Why it ranks #2: The 73.5-liter trunk bag mounts to most tour trunk racks, and its included waterproof rain cover adds practical weather protection.

With 73.5L of capacity, the Nelson-Rigg NR-300 offers substantial trunk-rack storage for touring riders carrying bulky luggage. UltraMax fabric resists fading and breakdown from natural elements, while reflective piping and an included waterproof rain cover address visibility and changing weather on the road.

The 22-by-12-by-14.5-inch bag mounts to most tour trunk luggage racks, with Harley Ultra, Honda Gold Wing, and Indian Roadmaster named among compatible applications. Its 73.5L capacity gives riders room for larger touring loads, while the UltraMax fabric is specified for fade resistance and resistance to natural-element breakdown. Reflective piping adds a visible detail, and the included waterproof rain cover provides a separate layer of protection when conditions turn wet.

Pros
  • 73.5L stated capacity
  • UltraMax fabric offers fade resistance
  • Reflective piping enhances visibility
  • Waterproof rain cover included
Cons
  • Its stated 73.5L capacity may be excessive for riders seeking a compact daily bag.

Skip it if you carry only a few daily essentials and prefer a compact 13L bag; the KEMIMOTO KMF1808-01809-BK is sized for that use.

This is for touring riders needing a high-capacity trunk-rack bag on applications such as Harley Ultra, Honda Gold Wing, or Indian Roadmaster. Its large 73.5L capacity makes it less suited to compact everyday loads.

Rhinowalk 40–60L Tail Bag

#3 · Most Expandable

3. Rhinowalk 40–60L Tail Bag

  • Capacity: 60 liters
  • Material: Polyester
  • Compatible with Vehicle Type: Motorcycle

Best for: Maximum-capacity motorcycle touring.

Why it ranks #3: It expands from about 40L to 60L and includes a large rain cover, four fixed straps, two extension straps, and a shoulder strap.

See also  Best Coolant For Hyundai Tucson: How to Choose the Right Formula

The Rhinowalk MT4060-1 expands from about 40L to 60L, making it the largest stated-capacity option in this set for riders carrying substantial touring luggage. Its double expansion zipper adds room when needed, while external pockets keep portable items easier to reach.

The main bag starts at about 40L and expands to 60L by opening the double expansion zipper, so riders can choose a smaller setup for lighter loads or more space for extended trips. Double-sided zippered pockets provide compartments for frequently needed portable items, reducing the need to open the main bag for every small item. The listed kit includes a shoulder strap, large rain cover, four large fixed straps, and two extension straps; at 4.6 pounds, the bag itself adds weight before packing.

Pros
  • Expands from about 40L to 60L
  • Double-sided zippered pockets for portable items
  • Includes a large rain cover
  • Shoulder strap and six listed mounting straps are included
Cons
  • The bag itself weighs 4.6 pounds before luggage is added.

Skip it if you want a lighter bag for a minimal daily load; the KEMIMOTO 13L KMF1808-01809-BK is a smaller-capacity option.

Choose this Rhinowalk for touring loads that benefit from up to 60L and separately accessible pockets. Account for its 4.6-pound empty weight, and use the included straps and rain cover as part of your packing setup.

Marscamd 33–40L Tail Bag

#4

4. Marscamd 33–40L Tail Bag

  • Capacity: 40 liters
  • Material: Polyester
  • Compatible with Vehicle Type: Motorcycle

Best for: Expandable essentials with rain cover.

Why it ranks #4: Its 33–40L expandable compartment has bottom panels to limit sagging, internal tie-down straps, access from three directions, and a rain cover.

The Marscamd expands from 33L to 40L and opens from the top or either side, letting riders reach packed gear without relying on a single access point. Its included rain cover adds a separate layer of protection for motorcycle trips in wet or dusty conditions.

Bottom panels help prevent the main compartment from sagging, while two internal elastic tie-down straps hold packed items in place during the ride. Unzipping the body increases capacity from 33L to 40L, giving you added space when a trip calls for more gear. Because the central compartment opens from the top and either side, you can reach contents from different positions around the motorcycle. The water-resistant fabric and included cover address changing weather.

Pros
  • Expands from 33L to 40L
  • Central compartment opens from the top and either side
  • Bottom panels help prevent sagging
  • Includes a rain cover and two internal tie-down straps
Cons
  • The fabric is described as water-resistant, so wet-weather protection also relies on the included rain cover.

Skip it if you want a stated waterproof fabric rather than water-resistant fabric with a rain cover; the KEMIMOTO 13L bag lists a waterproof rain cover.

This suits riders who want a mid-size expandable tail bag with multiple ways to access the main compartment and internal load restraint. Its fabric is water-resistant, and the included cover is part of the wet-weather setup.

KEMIMOTO 40–50L Tour Bag

#5

5. KEMIMOTO 40–50L Tour Bag

  • Capacity: 75 lb
  • Material: Oxford Cloth
  • Compatible with Vehicle Type: Tour models, Trike, Road King, Street Glide…

Best for: Expandable touring trunk capacity.

Why it ranks #5: This touring-focused bag expands from 40L to 50L and lists compatibility with Street Glide, Road King, Road Glide, Electra Glide, and Trike models.

The KEMIMOTO expands from 40L to 50L and is listed for touring models and Trikes, including Street Glide, Road King, Road Glide, and Electra Glide. Its increased height creates extra room for a larger touring load without changing to a different bag.

The listed 19.69-by-11.81-inch footprint and expandable height of up to 13.3 inches define how the bag gains capacity, from 40L to 50L. The product description says it can handle helmets or weeks' worth of clothing, making the extra volume useful for extended touring loads. It is specifically listed for several touring models and Trikes, so its compatibility is more focused than a general universal-fit claim. The description also identifies a wet-dry bag and mentions protection against theft and accidental openings.

Pros
  • Expands from 40L to 50L
  • Expandable height reaches 13.3 inches
  • Listed for named touring models and Trikes
  • Description identifies a wet-dry bag
Cons
  • Its listed compatibility is focused on touring models and Trikes rather than a broad range of motorcycle types.

Skip it if you ride a sportbike and need a bag listed for broader motorcycle compatibility; the KEMIMOTO B085997KQJ names many motorcycle models.

This KEMIMOTO fits touring riders and Trike owners seeking 40–50L of luggage space for helmets or clothing. Its model list is touring-focused, so riders outside those applications should review the stated compatibility carefully.

KEMIMOTO 25–30L Tail Bag

#6 · Best Daily-Ride Size

6. KEMIMOTO 25–30L Tail Bag

  • Capacity: 30 liters
  • Material: oxford
  • Compatible with Vehicle Type: Motorcycle

Best for: Quick-access commuting essentials.

Why it ranks #6: Its 25–30L capacity suits commuting or extra gear, while four adjustable straps and side pockets provide practical mounting and quick-access storage.

Side pockets for a water bottle and phone let the KEMIMOTO keep small daily items accessible without opening its main compartment. Its capacity expands from 25L to 30L, giving commuters a little extra room when a ride calls for a helmet and jacket.

The 25L starting capacity suits the listed daily-commute use, and opening the expansion panel adds space up to 30L for a helmet and jacket. Side pockets provide separate access to a water bottle or phone, so those items need not be packed inside the main compartment. Tear-resistant fabric is described as maintaining structure and resisting sagging or deformation with regular use. Four adjustable straps provide the stated four-point mounting approach for securing the bag to a motorcycle.

Pros
  • Expands from 25L to 30L
  • Side pockets hold a water bottle and phone
  • Tear-resistant fabric is described as maintaining shape
  • Four adjustable straps for four-point mounting
Cons
  • Its maximum stated capacity is 30L, less than larger touring bags in this roundup.

Skip it if you need more than 30L for extended touring; the Rhinowalk MT4060-1 expands to 60L for larger loads.

Choose this KEMIMOTO for commutes and short rides where quick access to a phone or bottle and 25–30L of storage fit the routine. Its stated capacity tops out at 30L, limiting room for larger touring loads.

KEMIMOTO 22–34L Dual-Use Bag

#7

7. KEMIMOTO 22–34L Dual-Use Bag

  • Capacity: 30 liters
  • Material: Leather, Polyester
  • Compatible with Vehicle Type: Motorcycle

Best for: Dual-use expandable touring bag.

Why it ranks #7: The 22–34L bag works as a tail bag or backpack and includes six straps, but a rear rack is suggested for stable use.

The KEMIMOTO converts between motorcycle tail-bag and backpack use, giving riders a way to carry luggage off the bike after parking. Its 22L-to-34L expansion adds packing room for clothes, shoes, tablets, meals, or a helmet sized L or smaller.

Expanding the bag raises its stated capacity to 34L, while the standard and expanded dimensions show how the taller profile adds room. Six straps are identified in the title, and the product is described as fitting many motorcycles; a rear rack is suggested for stable use on models without one. A waterproof zipper and rain cover help protect contents, while the reflective strip supports visibility on night rides. The stated helmet limit is size L and below.

Pros
  • Converts between tail bag and backpack use
  • Expands from 22L to 34L
  • Waterproof zipper design and rain cover
  • Reflective strip for night-riding visibility
Cons
  • It is designed for helmets size L and below, not larger helmets.

Skip it if you need to carry a helmet larger than size L; the Rhinowalk Y4045B lists helmet storage without this size limit.

Pick this KEMIMOTO if backpack carry matters as much as motorcycle storage and a 22–34L range suits your load. Check the helmet-size limit and note that models without a rear rack have limited compatibility.

KEMIMOTO 20–25L Tour Bag

#8

8. KEMIMOTO 20–25L Tour Bag

  • Capacity: 25 liters
  • Material: 1680D Oxford Cloth
  • Compatible with Vehicle Type: Motorcycle

Best for: Touring loads with helmet space.

Why it ranks #8: This touring-oriented bag expands from 20L to 25L, lists Street Glide, Road King, Road Glide, Electra Glide, and Trike compatibility, and fits two half helmets.

The KEMIMOTO expands from 20L to 25L and is described as able to accommodate two half helmets, giving touring riders a defined amount of extra space for gear. Its 1680D Oxford cloth construction and wet-dry bag address practical storage needs on rides.

The 20L-to-25L expansion lets riders increase space when packing needs grow, while the product description says the bag can fully accommodate two half helmets. Its 19.7-by-13.4-by-10.6-inch dimensions give a sense of the luggage footprint, and the listing names Street Glide, Road King, Road Glide, Electra Glide, and Trike applications. The 1680D Oxford cloth is the specified material, and the description also identifies a wet-dry bag for separating items during travel.

Pros
  • Expands from 20L to 25L
  • Description says it accommodates two half helmets
  • 1680D Oxford cloth construction
  • Wet-dry bag identified in the description
Cons
  • The listed compatible applications focus on touring models and Trikes.

Skip it if you need a higher stated capacity for an extended tour; the KEMIMOTO B09HYW81CT expands from 40L to 50L.

Pick this KEMIMOTO for listed touring models or Trikes when 20–25L and space for two half helmets suit the load. Its compatibility list is focused, so check that your motorcycle falls within those applications.

KEMIMOTO 13L Tail Bag

#9 · Most Compact

9. KEMIMOTO 13L Tail Bag

  • Capacity: 13 liters
  • Material: Polyvinyl Chloride (PVC)
  • Compatible with Vehicle Type: Motorcycle

Best for: Compact waterproof daily essentials.

Why it ranks #9: Its 13L capacity and listed 14.96-by-10.24-by-7.48-inch dimensions suit daily essentials, with a detachable shoulder strap and rain cover.

A 13L main compartment gives the KEMIMOTO a compact footprint for gloves, a water bottle, and other daily essentials on a rear rack or passenger seat. Its hard-shell EVA frame and included rain cover make it a focused choice for commutes, canyon runs, and short trips.

The 14.96-by-10.24-by-7.48-inch dimensions keep the stated 13L bag compact for a rear rack or passenger seat, while the main compartment is sized around everyday items rather than a large touring load. A hard-shell EVA frame works with 900D PVC mesh fabric and a 210D lining as the listed construction. The included rain cover supports wet-weather use, and a detachable shoulder strap offers a carry option after parking. Heavy-duty zippers are also specified.

Pros
  • Compact 13L main compartment
  • Hard-shell EVA frame
  • Includes a rain cover
  • Detachable shoulder strap and heavy-duty zippers
Cons
  • The 13L capacity is limited for riders carrying bulky touring luggage.

Skip it if you need space for bulky touring gear or multiple days of clothing; the KEMIMOTO B09HYW81CT expands to 50L.

This KEMIMOTO suits commuters and short-trip riders who want a compact 13L bag with a shoulder strap for off-bike carry. Its capacity is best matched to essentials, not bulky or extended-tour luggage.

KEMIMOTO 18–22L Sissy Bar Bag

#10

10. KEMIMOTO 18–22L Sissy Bar Bag

  • Capacity: 22 liters
  • Material: Leather
  • Compatible with Vehicle Type: Motorcycle

Best for: Compact cruiser and touring storage.

Why it ranks #10: The 18–22L capacity is useful for smaller loads, but the listing excludes several common motorcycle styles, including fully faired sportbikes and short-tail models.

The KEMIMOTO offers an 18–22L capacity range in a tail bag listed for touring models, cruisers, dirt bikes, dual-sport motorcycles, and Shadow Vulcan applications. That smaller volume suits riders who want a restrained luggage footprint rather than a large touring trunk bag.

At 15.7 by 13.3 by 10.6 inches, the bag provides a defined footprint for rear-seat or rack luggage, and its expandable 18–22L range adds some flexibility when the load grows. The listed compatibility covers several touring and cruiser categories, with examples including Street Glide, Road King, Road Glide, Electra Glide, Trike, and Shadow Vulcan. However, the listing excludes several motorcycle styles and notes that the bag has no removable shaping board, which matters for fit and structure expectations.

Pros
  • Expands from 18L to 22L
  • Listed for touring and cruiser motorcycles
  • Also lists dirt-bike and dual-sport compatibility
  • Compact stated dimensions of 15.7 by 13.3 by 10.6 inches
Cons
  • Not compatible with listed Softail FXDR, short-tail or bobber styles, or fully faired sportbikes.

Skip it if you ride a fully faired sportbike or a short-tail bobber; the KEMIMOTO B085997KQJ lists broad fit for many motorcycle models.

Consider this KEMIMOTO for a modest luggage load on a listed touring, cruiser, dirt-bike, or dual-sport application. Its compatibility exclusions are specific, and it does not have a removable shaping board.

Avoid a fit mismatch before mounting

Check the rack, seat, and motorcycle model together before choosing a bag; a general motorcycle label does not guarantee a stable fit. The KEMIMOTO 22–34L Dual-Use Bag states that models without a rear rack have limited compatibility and recommends a rack for stable use. The KEMIMOTO 18–22L Sissy Bar Bag lists exclusions including fully faired sportbikes, short-tail or bobber-style motorcycles, and bikes with high-mount tailpipes or dual exhausts.

By contrast, the Nelson Rigg NR-300 Traveler is described as mounting to most tour trunk racks, with Harley Ultra, Honda Gold Wing, and Indian Roadmaster named. Compare the bag’s stated model guidance with your actual mounting points and exhaust location.

The product information does not establish universal fit or confirm that every rack can support a loaded bag, so verify those details with the motorcycle and rack manufacturer before riding.

Rain covers and water-resistant claims are not identical

Treat a rain cover and a water-resistant bag as separate layers of protection rather than assuming either guarantees a dry load in every downpour. The Rhinowalk 33–45L Tail Bag is described as able to resist rain and keep luggage dry, and its title lists a helmet rain cover. The Marscamd 33–40L Tail Bag is made from water-resistant fabric and comes with a cover intended to keep water and dust off the bag.

The Nelson Rigg NR-300 Traveler also includes a waterproof rain cover. The KEMIMOTO 22–34L Dual-Use Bag instead highlights a waterproof zipper design.

These are useful but different listed features; the supplied details do not specify a rain-duration rating or submersion protection. For wet-weather travel, check that the cover is packed and fitted, close zippers fully, and keep items that cannot get wet in an additional protective layer.

How to Choose a Motorcycle Rack Bag

Capacity and expansion

Choose capacity based on what you carry regularly, then use expansion for occasional extra gear. The listed range runs from the 13L KEMIMOTO 13L Tail Bag to the 73.5L Nelson Rigg NR-300 Traveler. Expandable options include the 18–22L KEMIMOTO 18–22L Sissy Bar Bag, the 25–30L KEMIMOTO 25–30L Tail Bag, the 33–45L Rhinowalk 33–45L Tail Bag, and the 40–60L Rhinowalk 40–60L Tail Bag.

A smaller bag suits commuters carrying essentials, while riders packing clothing or larger items may prefer a 30L-plus option. Touring with bulky loads favours the highest capacities, but consider the bag’s dimensions and your available mounting area rather than choosing on liters alone.

Motorcycle and mounting compatibility

Prioritize a bag whose stated fit guidance matches your motorcycle and actual mounting points. The Nelson Rigg NR-300 Traveler is designed for most tour trunk racks and names Harley Ultra, Honda Gold Wing, and Indian Roadmaster among examples. The KEMIMOTO 40–50L Tour Bag lists touring models including Street Glide, Road King, Road Glide, Electra Glide, and Trike.

The KEMIMOTO 22–34L Dual-Use Bag fits many motorcycles but says a rear rack is suggested for stable use, while the KEMIMOTO 18–22L Sissy Bar Bag names several exclusions. Touring riders should favour a model with relevant model guidance; riders on other bikes should verify clearance and attachment points before buying.

Do not infer fit solely from a broad motorcycle compatibility label.

Structure, straps, and weather protection

Look for support and attachment details that match the load and conditions you expect. The Rhinowalk 33–45L Tail Bag has a reinforced steel-wire and PE-board frame plus a non-slip, wear-resistant base. The Marscamd 33–40L Tail Bag uses bottom panels and two internal tie-down straps, while the Rhinowalk 40–60L Tail Bag includes four fixed straps and two extension straps.

Weather features also vary: several bags include rain covers, the KEMIMOTO 22–34L Dual-Use Bag highlights a waterproof zipper, and the Nelson Rigg NR-300 Traveler uses UltraMax fabric with an included waterproof cover. Riders carrying heavier or awkward loads may favour listed structure and securing straps; wet-weather riders should value a cover or other stated protection.

Check what is actually included for the chosen product.

Which Motorcycle Rack Bag Should You Choose?

For an all-round expandable rack bag, choose the Rhinowalk 33–45L Tail Bag: its reinforced frame, non-slip base, rain resistance, and sissy bar straps suit varied loads. If maximum listed capacity matters for a tour trunk rack, the Nelson Rigg NR-300 Traveler offers 73.5 liters and an included waterproof rain cover. For bulky touring luggage with expansion, the Rhinowalk 40–60L Tail Bag reaches 60 liters and includes multiple mounting straps.

Commuters carrying moderate loads can consider the KEMIMOTO 25–30L Tail Bag, with side pockets and four adjustable straps. For compact daily essentials, the KEMIMOTO 13L Tail Bag is smaller and comes with a shoulder strap and rain cover.

Confirm model fit, rack support, and exhaust clearance before deciding.

Frequently Asked Questions

How can I check whether a tail bag will fit my motorcycle’s rack and exhaust?

Compare the bag’s stated fit information with your motorcycle and rack, and check the rack’s usable surface and attachment points. Allow clearance from the exhaust, including when the bag is loaded and straps are tightened. If fitment or heat clearance is uncertain, consult the motorcycle and bag manufacturers before riding.

How should I secure a motorcycle luggage bag to prevent movement on a ride?

Use the bag’s supplied straps at suitable rack or frame attachment points, and tighten them evenly so the bag cannot slide or rock. Keep straps clear of the exhaust, wheel, suspension, and controls. Recheck tension after loading and before riding; stop safely if the bag shifts or a strap loosens.

What steps help protect luggage inside a motorcycle bag during heavy rain?

Use the bag’s included rain cover when supplied, and place moisture-sensitive belongings in separate waterproof inner bags. Close zippers and openings fully, then check that the cover is secured before setting off. Rain resistance or a cover may not guarantee a completely dry interior in prolonged heavy rain.

How much capacity should I choose for my usual rides?

Choose capacity around the load you regularly carry, with room for occasional extra items. The listed options range from a 13L compact bag to a 73.5-liter tour trunk bag; expandable choices include 33–45L and 40–60L. Consider rack support and secure mounting as well as volume, especially for bulky touring luggage.

Can a motorcycle tail bag be carried off the bike?

Some options include carrying features, but they vary by bag. The 13L KEMIMOTO listing specifies a detachable shoulder strap, while another KEMIMOTO option is described as a backpack. Check the individual product’s included straps and carry style, and remove or secure loose straps before mounting the bag for a ride.

Final Words

For a versatile expandable rack bag, the Rhinowalk 33–45L Tail Bag is the strongest overall choice here, with its reinforced frame, non-slip base, rain resistance, sissy bar straps, and helmet rain cover. Choose the Nelson Rigg NR-300 if its listed 73.5 liters better suits tour-trunk loads. For bulky luggage, consider the Rhinowalk 40–60L; for commuting or essentials, look at the 25–30L or 13L KEMIMOTO.

Confirm fit, rack support, and exhaust clearance.
