Which Motorcycle Tail Bag Fits Your Ride? 10L to 45L Options from $35.72

Choosing a motorcycle tail bag comes down to matching cargo space with ride style. In the powersports luggage storage and towing space, you'll find everything from a compact 10L commuter bag to a 45L expandable touring trunk. The four rear luggage options here cover that spread, with listed prices ranging from USD 35.72 to USD 119.39. Here's how they compare.

How to choose

For a tail bag, think about three things first: how much gear you carry, how often you ride in rain, and how easy the bag is to handle off the bike. A compact bag can handle errands, while a touring-oriented trunk gives you room for a weekend load.

Quick take

• The MOTOFORTI 1680D Backpack is the compact pick, with a rain cover and expandable bottom section in the description.
• The NICECNC Seat Pack adds a waterproof cover and lists compatibility with several major bike brands.
• The SAGA MOTO Rear Trunk Bag is a large touring-style option with side straps.
• The SAGA MOTO Expandable Rear Trunk Bag is described as expanding its capacity and includes a rain cover.

Decision matrix

MOTOFORTI 1680D Backpack

This compact rear-seat bag is made from 1680D and described as waterproof and heat-insulating. It comes with a rain cover and buckle straps, and the description notes an expandable bottom section. That makes it a simple, portable option for riders who want to carry small essentials on shorter trips. The limitation is weather readiness: the description says it is lightly waterproof and not recommended for heavy rain. If your commute includes downpours, the NICECNC option's included waterproof cover may be worth considering.

NICECNC Seat Pack

This tail bag uses upgraded PVC material and a PU waterproof zipper, and it includes a waterproof cover. The description also lists compatibility across many Honda, Kawasaki, KTM, Suzuki, Yamaha, and BMW models from 2013 through 2023. That makes it a convenient match for a wide range of bikes. The trade-off is scope: it's a middle-size seat pack, so it suits day rides and commuting better than multi-day touring. Riders packing bulky gear should look up to the SAGA MOTO trunk bags.

SAGA MOTO 40L Rear Trunk Bag

This is the bag for riders who want a large rear trunk straight out of the box. The description points to touring, commuting, camping, and everyday use, with water-resistant construction for light rain, dust, and road debris. It also includes side straps and a 3 lb item weight. If you prefer a fixed large capacity without the expandable range described on the other SAGA MOTO bag, this one keeps the spec simple. The main thing to weigh is the initial outlay, since it sits at the top of this comparison's price range.

SAGA MOTO 45L Expandable Rear Trunk Bag

This SAGA MOTO bag shares the same basic title as the 40L version but is described as expanding from 40L to 60L, with an included rain cover and reinforced internal structure. If your load changes from a solo overnighter to a longer tour, that expandable range gives you room to adapt. The trade-off is physical: the item weight is 10 lb, while the 40L SAGA MOTO bag lists 3 lb. That extra weight is worth remembering if you'll be lifting the bag on and off the bike frequently.

Final recommendation by use case

• For a compact rear bag with a rain cover, the MOTOFORTI 1680D Backpack is a practical starting point.
• For broad bike compatibility and wet-weather details, the NICECNC Seat Pack is a strong mid-size match.
• For a large, straightforward touring trunk, the SAGA MOTO Rear Trunk Bag has the side straps and water-resistant build.
• For expandable storage, the SAGA MOTO Expandable Rear Trunk Bag is the one to check.
