Our Take
The KEMIMOTO Motorcycle Tail Bag is an expandable 22–34L rear seat bag that doubles as a backpack or handbag. It’s built from 1680D fabric, includes a dedicated rain cover and upgraded waterproof zipper, and is aimed at riders who want a weather-ready, medium-capacity luggage option for street bikes.
The bag is practical for commuting or short trips: internal mesh storage fits tablets up to 11 inches, a zippered side pocket holds small items, and external reflective striping improves night visibility. It’s marketed as fitting full and half helmets but carries an important caveat — the bag is designed to fit helmets sized L and below only.
Main trade-offs are compatibility and capacity limits. The bag is suggested for motorcycles with a rear rack for stable mounting and is not intended for dirt bikes or bicycles. Riders with larger helmets or who need heavy-duty rack-mounted luggage should confirm fit before buying.

Scoring Breakdown
How It Performs
Design & Build Quality
Construction uses 1680D Oxford cloth with a scratch-resistant finish. The bag includes an installation buckle and universal straps for mounting. The manufacturer highlights an upgraded waterproof zipper and a dedicated rain cover. Exact waterproof ratings or internal frame details are not supplied.
Comfort & Fit
The bag converts to a backpack or handbag, which adds convenience for walking off the bike. Padding and strap ergonomics are not specified, so long carries may be limited by the unknown padding and strap design.
Performance
With the bag expanded, advertised capacity reaches 34L and the inner space claims to accept full and half helmets within the L-size limit, clothing and small luggage. Performance on-road will depend on secure attachment; models without a rear rack have limited compatibility and a rack is recommended for stable use.
Features
Key features from the product facts include expandable capacity, inner mesh pocket for an 11-inch tablet, a zippered side pocket, reflective strips for visibility, waterproof zipper and included rain cover. It also lists scratch-resistance and a stable installation buckle design.
Ease of Use
Installation is via universal straps and a buckle system; the bag also converts to backpack/handbag modes for easy off-bike movement. Specifics on strap routing or quick-release mounting are not provided.
Battery Life
N/A — the tail bag has no electronic components.
Durability
The 1680D fabric and scratch-resistant treatment suggest reasonable durability for everyday street use. The product facts state the material resists tearing and water to a degree, but no laboratory ratings or lifespan claims are provided.
Value for Money
At the listed price, the bag offers a combination of expandability, weather protection and conversion to backpack mode that represents solid value for riders needing a mid-capacity solution. Buyers wanting heavy-duty luggage or larger helmet capacity should compare alternatives.
Real-World Use
The bag is aimed at street motorcycles and examples given include models such as CB600RR, iron883, MT10, FZ07/09 and R1200GS. It stores clothes, shoes, tablets (up to 11"), cameras and helmets up to size L. It is not intended for dirt bikes or bicycles.
Comparison With Competitors
Compared with basic tail bags, this model adds a higher-density 1680D material, an included rain cover and a waterproof zipper. Riders should review rack compatibility and helmet-size needs when comparing to larger dedicated luggage or hard cases.
Fit & Suitability
Who Is This Product For?
Who Should Buy It
Riders who want an expandable, weather-aware tail bag that doubles as a backpack for short off-bike trips, and who have a street motorcycle with a rear rack or secure mounting points.
Who Should Consider Alternatives
Riders with helmets larger than size L, those who frequently ride dirt bikes or bicycles, or riders who require hard-case security or very large capacity should look elsewhere.

The bag uses water-resistant 1680D fabric, an upgraded waterproof zipper and includes a dedicated rain cover to protect contents in rainy conditions. No formal waterproof rating is supplied.

Will it fit my motorcycle?
