KEMIMOTO 55L ATV Rear Seat Storage Bag — Water-Resistant 900D Fabric, Reinforced Frame

KEMIMOTO 55L ATV Rear Seat Storage Bag is a reinforced, water-resistant cargo and passenger seat bag designed to organize gear, protect contents, and provide a cushioned rear seat on most rack-equipped ATVs.

Built for off-road riders who need dependable storage without sacrificing comfort, this KEMIMOTO rear seat bag combines a 55-liter capacity with reinforced framing, YKK hidden zippers, and 900D water-resistant fabric. It mounts securely to ATV racks or panel grooves using seven adjustable straps and includes detachable internal shelves, side pockets, and reflective seams for low-light visibility.

How much gear will the 55L rear seat bag actually hold?

The bag offers a spacious 55-liter interior with external dimensions of 33.07" × 17.3" × 9.05", letting you carry bulky camping items or multiple small accessories. Elastic and self-fastening straps inside keep long or awkward items stable so the load remains compact and accessible.

• Overall capacity: 55 liters (33.07" × 17.3" × 9.05")
• Three removable internal shelves for separated storage
• Two external pockets fit bottles or small personal items (diameter <3.5")
• Top surface supports up to 5 kg when used as a passenger cushion

Will it survive mud, branches, and rainy trails?

The shell is constructed from durable 900D fabric with reinforced stitching to resist wear from brush and general off-road abrasion. A widened brim and protective fabric cover shield the high-quality YKK zippers to reduce exposure to dirt and moisture, improving long-term reliability.

• 900D water-resistant, wear-resistant outer fabric
• Hidden YKK zippers with protective fabric cover for reduced debris intrusion
• Sealed seams and tight stitching help keep contents cleaner
• Avoid prolonged heavy rain or vehicle wash to extend life

How stable and easy to mount is the KEMIMOTO ATV rack bag?

An upgraded integrated frame prevents the bag from sagging or shifting while riding, and seven adjustable attachment straps secure it to a wide range of ATV racks and panels. Two side grab handles let you lift the bag on and off quickly, and the removable internal shelves make it lighter when you only need soft storage.

• Integrated frame maintains bag shape and prevents shifting
• Seven adjustable straps provide a universal, secure fit on many ATV models
• Two grab handles for easier loading/unloading
• Detachable internal shelves for flexible configuration and lighter carry

Does it add comfort or visibility for passengers?

The top of the bag includes a breathable cushion that improves passenger comfort for short trips; the cushion can be packed away with self-fastening straps when not needed. Reflective strips are sewn along the seams to increase visibility to others during low-light conditions.

• Breathable top cushion for added passenger comfort
• Cushion stows inside using self-fastening straps
• Reflective seam strips improve night visibility
• Designed to fit popular ATVs like Polaris Sportsman, Rancher, Foreman, Grizzly and more

Who is this for: Riders and outdoor enthusiasts who want a rugged, high-capacity storage solution that doubles as a passenger pad on many ATV models. It suits weekend campers, trail riders, and utility users who need organized compartments, reliable zippers, and a stable mount—while avoiding bulky hard cases. Note: measure your ATV seat length (bag length 33.07") to confirm fit, follow top-mount guidance for heavy loads, and avoid prolonged exposure to heavy rain to preserve materials.
