KEMIMOTO Motorcycle Tail Bag 30L–45L Expandable Waterproof Rear Rack Trunk with Rain Cover & Removable Divider

KEMIMOTO's expandable motorcycle tail bag is a weatherproof, 30L–45L rear rack trunk that converts between compact and roomy storage, protecting gear with PVC-coated fabric, a removable divider, and a rain cover.

This travel luggage is designed for riders who need flexible storage on day rides, overnight trips, or multi-day touring. It expands from 30 liters up to 45 liters when you need extra room, secures to most motorcycle racks with four adjustable straps, and stows smaller essentials in external pockets. Built to resist water, dust, and scuffs, the bag includes a removable PE divider to preserve shape and organize contents, plus reflective details to improve visibility after dark.

How does the bag expand and stay organized on long rides?

The KEMIMOTO tail bag uses an expanding core that unlocks extra volume when you need it, then compresses back to a slimmer profile for short trips. Inside, the removable PE divider and internal pockets let you separate helmet liners, clothing, and tools for quick access.

• Expandable main compartment toggles between 30L and 45L capacity
• Removable PE divider keeps the bag structured and items separated
• Exterior side pockets for water bottles or small accessories

What weather protection does the bag offer during adverse conditions?

Constructed from PVC-coated mesh and lined with 210D fabric, the bag resists rain, dust, and road grime while maintaining tear strength. For heavier spray or sudden showers, a supplied waterproof rain cover slips on quickly to shield seams and zippers.

• Durable PVC clip mesh for water and abrasion resistance
• Included waterproof rain cover for added protection in wet weather
• 210D inner lining enhances durability and helps the bag keep its shape

Will this fit my motorcycle and how secure is it during rides?

Installation is simple: four adjustable straps with quick-release buckles attach to most rear racks, passenger seats, or luggage plates. The anti-reflective strap buckles improve nighttime visibility, and the wide attachment points reduce sway on highways.

• Four straps and buckles for stable mounting on various motorcycle types
• Compatible with ADV touring bikes, street bikes, and retro cruisers
• Shoulder strap included for easy off-bike carrying

How easy is it to carry and access items off the bike?

A detachable shoulder strap converts the pannier into a carry bag for grocery stops or campsite use, while side pockets keep essentials reachable without opening the main compartment. Zippers and buckles are designed for one-handed use when you're balancing on foot or in a parking lot.

• Removable shoulder strap for off-bike transport
• External pockets allow quick access to snacks, phone, or bottle
• Thoughtful zipper and buckle placement for convenient one-handed access

Who is this for: Riders who need dependable, flexible luggage for commuting, weekend touring, or multi-day motorcycle travel will appreciate the KEMIMOTO expandable tail bag. It suits motorcyclists who want extra carry capacity without sacrificing weather protection or secure mounting, and it’s a good fit for those who value quick access to small items and improved nighttime visibility. Whether you ride an ADV, street bike, or retro cruiser, this bag delivers adaptable storage and durable construction for everyday use and longer adventures.
