KEMIMOTO 55L ATV Rear Seat Storage Bag — 55L water-resistant rear rack bag with padded seat

KEMIMOTO 55L ATV Rear Seat Storage Bag is a heavy-duty, water-resistant rear rack and seat caddy that organizes gear, protects supplies, and adds a cushioned passenger seat for two-up riding.

Designed for utility riders and weekend explorers, this KEMIMOTO rear seat bag combines large-capacity storage, reinforced structure, and weather-resistant materials so you can carry tools, camping gear, or everyday essentials on a wide variety of ATVs. The bag’s rigid internal frame keeps its shape, YKK hidden zippers resist dirt and corrosion, and seven adjustable attachment straps secure the pack to racks or panels with grooves.

How much gear can the bag carry and what fits inside?

The bag offers a 55-liter capacity with overall dimensions of 33.07" x 17.3" x 9.05", designed to take long items and bulkier supplies while keeping them organized. Three removable internal shelves let you adapt the interior for taller or longer items, and two exterior pockets hold drinks or small essentials.

• 55L total capacity; measures 33.07" x 17.3" x 9.05"
• Three detachable internal shelves for customizable storage
• Two outside pockets fit bottles up to 3.5" diameter
• Elastic and hook-and-loop straps secure odd-shaped gear

What protects my gear from mud, dust, and rain?

The bag is built from 900D fabric for abrasion and water resistance so light rain and splashes stay out. KEMIMOTO uses YKK hidden zippers under a fabric brim to improve airtightness and prevent dirt from jamming the closures; still, avoid leaving the bag exposed to heavy, prolonged downpours.

• Durable 900D water-resistant, wear-resistant fabric
• YKK zippers hidden beneath a protective fabric cover
• Widened zipper brim increases resistance to dust and debris
• Quick wipe-clean recommended after heavy exposure

Will this bag stay stable on bumpy trails and support a passenger?

An integrated reinforced frame helps the bag hold its shape and prevents shifting when you ride; seven attachment straps and a recommended top mounting system lock it to the rack for stability. The padded top doubles as a passenger seat cushion with a rated top-load of up to 5 kg when used correctly.

• Upgraded integrated frame for structural stability
• Seven adjustable attachment straps for a universal fit
• Two side grab handles for easy removal and carrying
• Padded seat top supports up to 5 kg when mounted properly

Who is this for? The KEMIMOTO 55L ATV Rear Seat Storage Bag is ideal for off-road riders who need organized, weather-resistant carry space without sacrificing passenger comfort. It suits utility riders, hunters, campers, and anyone who wants a robust, versatile caddy that works with Polaris, Sportsman, Rancher, Foreman, Grizzly and many other ATVs featuring racks or grooved panels. Follow the mounting guidance and routine care to get the best life and performance from the bag.
