Featured on the cover of the April 1998 Dirt Bike Magazine and the cover of the May 1998 Motocross Action Magazine, and more than 8 other Offroad Magazine covers worldwide, 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 4SMX XR600 seat/tank kit costs just $499 plus shipping, and is available online.
