Best Sissybar Bags For Motorcycles Large: 10 Options Compared

#1 · Best Overall

1. HCmotorku Expandable Sissy Bar Bag

• Material Type: Nylon
• Compatible with Vehicle Type: Motorcycle
• Size: 50L-80L

Best for: High-capacity expandable travel bag.

Why it ranks #1: Its listed 50L–80L capacity targets large loads, and the bag is described as expandable and usable as a tail bag, shoulder bag, or handbag.

An expandable range of 50 to 80 liters makes this HCmotorku bag the high-volume choice for riders carrying clothes, drinks, or tools. Its listing names Harley, Yamaha, and Suzuki among compatible makes, and the bag can also serve as a tail bag, shoulder bag, or handbag.

The 50–80L range gives riders room to increase luggage volume for travel, camping, or other outdoor activities. A zipper pocket adds a separate spot for carry-on items, while the nylon construction keeps the listed material straightforward. The product is described for most motorcycles and specifically names Harley, Yamaha, and Suzuki; its multiple roles as a tail, shoulder, or hand bag let owners switch between motorcycle mounting and carrying it off the bike.

Skip it if you want a smaller 30L bag rather than high-volume luggage; the KEMIMOTO F1824-00214-BK has a 30L capacity.

This suits riders on longer trips who need substantial expandable space and multiple ways to carry the bag. Its 1.5 kg listed weight and large capacity are worth considering when packing and handling it off the motorcycle.

#2 · Best Rain Kit

2. Rhinowalk Expandable Tail Bag

• Material Type: Polyvinyl Chloride (PVC)
• Compatible with Vehicle Type: Motorcycle
• Size: 33-45L

Best for: Expandable all-weather touring luggage.

Why it ranks #2: The 33–45L capacity suits substantial luggage, while the listing describes rain resistance and includes a helmet rain cover.

Expansion from about 33 to 45 liters gives the Rhinowalk tail bag room to adapt when a ride calls for extra cargo space. Its listing also specifies rain resistance and a helmet rain cover, combining adjustable luggage volume with weather-oriented protection for touring gear.

The double-sided retractable zipper changes the bag from its normal 33-liter capacity toward a maximum of 45 liters, allowing riders to increase space for a larger load. Tear-resistant mesh cloth, reinforced steel wire, and a PE board support the bag’s frame, while anti-slip material on the base helps it stay stable on a surface. It is listed as a tail bag with sissy bar straps and can hold items including sleeping bags, laptops, cameras, or helmets.

Skip it if you need more than 45L of luggage space; Goldfire’s HD-LSSBG-001 reaches 65L.

This suits riders who want expandable tail luggage, sissy bar straps, and listed rain protection for touring gear. Its 45L maximum is the practical boundary for trips that require a larger cargo load.

#3 · Wide Capacity Range

3. Goldfire Expandable Tail Duffle

• Material Type: Nylon
• Compatible with Vehicle Type: ATV, Bicycle, Car, Motorcycle, Scooter…
• Size: Large

Best for: Expandable 65L multi-vehicle duffel.

Why it ranks #3: Its 40L–65L expandable range covers larger trips, and quick-mount sissy bar straps, welded D-rings, and a removable shoulder strap add mounting and carry options.

Expansion to 65 liters gives the Goldfire duffel room for a larger touring load, while quick-mount sissy bar straps make motorcycle setup direct. Welded D-rings offer alternate mounting options, and its listed vehicle compatibility extends beyond motorcycles to several other vehicle types.

The 40–65L capacity range lets riders adjust the available luggage space to the load, rather than always carrying the maximum volume. Quick-mount straps serve sissy bar use, while welded D-rings provide other mounting options when a sissy bar or backrest is not used. The low-profile handle and removable shoulder strap support carrying it away from the bike. Its listed compatibility includes motorcycles, ATVs, bicycles, cars, scooters, snowmobiles, trucks, and UTVs.

Skip it if you need an 80L maximum for especially large loads; the HCmotorku HCUSLU000301 lists up to 80L.

This fits riders seeking adjustable touring space and carry options across multiple vehicle types. Its 65L ceiling is the key boundary for buyers whose packing needs exceed the listed maximum.

#4 · Best Convertible

4. MOSISO Sissy Bar Bag

• Material Type: Polyester
• Size: L

Best for: Expandable 30–48L carry-all.

Why it ranks #4: The listed 30L–48L capacity expands for extra luggage, and the bag can also be carried as a shoulder bag or handbag.

The MOSISO bag starts with a 30-liter main compartment and expands to a listed 48-liter maximum, letting riders adjust space for different trips. It also converts between motorcycle tail-bag, shoulder-bag, and handbag use, so its carrying role can change when the ride ends.

The 30-liter main compartment provides a defined starting volume for clothes, drinks, tools, and other travel necessities, while expansion raises the listed maximum to 48 liters. Its 18.1-by-12.2-by-12.2-inch dimensions offer a clearer sense of its overall footprint for packing and storage. The three stated carry modes—tail bag, shoulder bag, and handbag—make it possible to take the luggage off the motorcycle without limiting use to a mounted bag.

Skip it if you need a 65L maximum for larger loads; the Goldfire HD-LSSBG-001 expands to 65L.

This suits riders who want a defined 30L main compartment with room to expand and a choice of carrying modes. Its 48L maximum is the relevant boundary for trips that require more luggage space.

#5 · Best 40L Duffel

5. Sresk 40L Sissy Bar Bag

• Material Type: Nylon
• Compatible with Vehicle Type: Motorcycle
• Size: One Size

Best for: 40L duffel with alternate mounting.

Why it ranks #5: Its stated 40L capacity, quick-mount sissy bar straps, adjustable bungee storage, and removable shoulder strap suit riders seeking a versatile travel duffel.

At 40 liters, the Sresk bag gives riders a substantial main luggage option, with quick-mount sissy bar straps for a direct motorcycle setup. Welded D-rings add alternative mounting points when a sissy bar or backrest is not being used, giving the duffel more than one way to attach.

Quick-mount straps support use on a sissy bar, while heavy-duty welded D-rings provide other secure mounting options without a sissy bar or backrest. An external adjustable bungee system offers a place for a coat or bedroll, keeping those items outside the main luggage space. Side zip pockets include MOLLE modular attachment, and the low-profile handle plus removable shoulder strap make carrying the 40-liter bag off the motorcycle more convenient.

Skip it if you need up to 65L of expandable capacity; the Goldfire HD-LSSBG-001 lists a 65L maximum.

This suits riders who want 40L of luggage with several mounting choices, external bungee storage, and shoulder carry. Its stated capacity is a consideration for longer trips requiring more room than a 40-liter load.

#6

6. KEMIMOTO 30L Sissy Bar Bag

• Material Type: Oxford, Polyvinyl Chloride (PVC)
• Compatible with Vehicle Type: Motorcycle
• Size: 30L

Best for: Multi-mount 30L touring bag.

Why it ranks #6: The 30L bag has multiple compartments and pockets, a waterproof rain cover, and mounting options for a tail rack, rear seat, or sissy bar.

The 30-liter capacity gives riders room for clothes, a motorcycle cover, water bottles, and snacks, while multiple compartments and pockets help separate those essentials. KEMIMOTO also supports several carrying arrangements, so the bag can move between the bike and off-bike use without relying on a single mounting position.

Mount it on a sissy bar, tail rack, or rear seat to suit the bike’s available luggage setup. The Oxford and PVC construction is paired with a waterproof rain cover, giving riders a stated rain-protection option for packed gear. Multiple compartments and pockets help organize items such as clothing and snacks, while the shoulder-bag and handbag options make it easier to carry the luggage away from the motorcycle. Its listed capacity is 30 liters.

Skip it if you need expandable cargo space beyond 30L; HCmotorku’s expandable 50–80L bag offers more room.

This suits riders who want organized 30L storage that can mount in several places and carry off the bike. Choose it when those options matter more than the greater expandable capacity of larger touring bags.

#7

7. Nomad USA 30L Sissy Bar Bag

• Material Type: 1000D Cordura
• Compatible with Vehicle Type: Motorcycle
• Size: 30L

Best for: Roll-top touring and laptop carry.

Why it ranks #7: Its 30L listing includes a variable-capacity roll top, a 15-inch laptop sleeve, and large zipper pockets, though its stated capacity is below several rivals.

A roll-top closure lets riders vary the bag’s capacity and creates a stated waterproof seal, making this Nomad a practical choice when packing loads change between trips. Its 30-liter format also includes a sleeve for a 15-inch laptop, pairing riding luggage with a dedicated place for a computer.

The 1000D Cordura construction and roll-top closure connect rugged fabric with an adjustable opening: riders can change the packed volume while using the seal intended to keep water out. A laptop sleeve and large zipper pockets provide separate places for a computer and frequently used items, reducing the need to dig through the main load. It can be carried as a handle or shoulder bag, so the same luggage can leave the motorcycle with its rider.

Skip it if you need 45L or more for bulky touring gear; the Rhinowalk Y4045B expands to 45L.

This is suited to riders combining a variable touring load with a 15-inch laptop and off-bike carry. Its listed 30L size is a boundary to consider if a trip calls for substantially more luggage space.

#8

8. Milwaukee Leather SH688 Bag

• Material Type: Textile
• Compatible with Vehicle Type: Motorcycle, Scooter
• Size: Large

Best for: Five-pocket retractable luggage.

Why it ranks #8: This large 1200D textile bag expands and has five outer pockets, a large main zippered compartment, and universal back mounting straps and buckles.

Five outer pockets give the Milwaukee Leather SH688 multiple places for smaller riding items around its huge main zippered compartment. Its retractable format expands easily, and universal back mounting straps and buckles provide the stated way to secure the bag to a sissy bar or backrest.

The 1200D textile material is described as weather resistant, a useful feature for luggage exposed to riding conditions. Universal back mounting straps and buckles support installation on a sissy bar or backrest, while the retractable format expands to accommodate changing loads. Five outer pockets separate smaller items from the large main zippered compartment, making frequently needed gear easier to keep apart from bulkier cargo. The listing does not specify a capacity in liters.

Skip it if you need a stated liter capacity before packing; the MOSISO MOMTSiyBKSHDRCB001 lists a 30L main compartment.

This fits riders who prioritize multiple outer pockets, a large zippered compartment, and retractable storage on a sissy bar or backrest. Its missing capacity figure is a boundary when matching luggage volume to a trip.

#9

9. Milwaukee Performance SH689 Bag

• Material Type: Textile
• Compatible with Vehicle Type: street-cruiser-motorcycles
• Size: Large

Best for: Street-cruiser backpack carry.

Why it ranks #9: The large 1200D nylon bag is listed for street-cruiser motorcycles and includes backpack straps, but the supplied specifications do not state its capacity.

Backpack straps are the key distinction of Milwaukee Performance’s large 1200D nylon sissy bar bag, letting riders carry the luggage on their back after removing it from the motorcycle. Its street-cruiser compatibility makes it a focused option for riders who want a motorcycle-mounted bag with backpack-style portability.

The 1200D nylon construction gives this bag a specified textile material, while the included-component listing identifies a sissy bar bag for motorcycle luggage use. Backpack straps add an off-bike carrying option, useful when a rider needs to take the bag along rather than leave it mounted. It is listed for street-cruiser motorcycles and in a large size; no capacity figure is supplied, so buyers cannot compare its volume precisely against liter-rated luggage.

Skip it if you need a stated liter capacity before choosing; the KEMIMOTO F1824-00214-BK lists 30L.

This fits street-cruiser riders who value backpack carry and a large 1200D nylon bag. Consider the missing capacity figure before choosing it for a trip where a specific cargo volume is important.

#10

10. Milwaukee Leather 2-Piece Bag Set

• Material Type: Polyvinyl Chloride (PVC)
• Compatible with Vehicle Type: Motorcycle, Scooter
• Size: Large

Best for: Two-piece modular touring storage.

Why it ranks #10: The large two-piece set offers flexible storage and weather-resistant materials, but the supplied listing gives no capacity or expandable volume.

A two-bag configuration gives this Milwaukee Leather set a modular approach to sissy bar storage, letting riders add flexible luggage for commuting, weekend rides, or touring without hard luggage. Its large-size listing and strap-mounted format focus on motorcycle and scooter owners seeking a paired soft-bag setup.

The set is intended for motorcycles equipped with a sissy bar or backrest, so its mounting approach depends on that equipment. Two pieces provide flexible carrying options across different rides, while the stated weather-resistant materials address dust and road exposure. The listed dimensions are 18 by 12 by 12 inches, but no capacity in liters is provided; riders planning a particular load should account for that when comparing it with capacity-rated luggage.

Skip it if you need a stated liter capacity for trip planning; the Rhinowalk Y4045B lists 33–45L.

This is for riders with a sissy bar or backrest who want a two-piece soft-luggage arrangement for commuting or touring. Its unstated capacity makes it less straightforward to size for a specific packing list.
