Our Aloop Seat/tank kit for the XR250 and XR400 includes a new 2-gallon fuel tank, a new flatter seat, CR-style radiator plastic, cool new graphics, and all the brackets and hardware you need to install. No permanent modifications to your bike are needed, and you'll be riding in about an hour!
Featured on the covers of over 10 offroad magazines worldwide, including The Dirt Bike Magazine and Motocross Action Magazine, ALOOP's XR400 Seat Tank kit is a "must-have" item for any XR400 performance rider.
The kit consists of a 2.0 gallon motocross tank (just .8 gallon less than the stock tank), a new seat with CR-style foam and a Guts Racing non-slip seat cover, and two CR-style radiator shrouds complete with genuine Guts graphics. The new tank is set up to use two fuel petcocks for better fuel delivery under race conditions.
Most importantly, the ALOOP Tank allows the rider to sit more than 3 inches further forward, more than an inch higher, and the tank is more than three inches narrower at the knees. The Aloop kit reuses your stock fuel cap, left side petcock, and front tank mounting brackets and rubber bushings.
