2007 Suzuki QuadRacer R450

Posted on by

An ATV like no other.
In a world where most riders are used to taking a stock sport ATV and bolting on a long list of aftermarket parts before heading to the racetrack, the 2007 LT-R450 is a whole new concept.

A machine built for racing, with the help of WPSA Champion Doug Gust.

Nothing tests an ATV more then Racing

It is a sport in which machine engineering and rider confidence must combine to produce winning speed.

The 2007 Suzuki LT-R450 Quadracer. A ready-to-race ATV designed, developed and tested by a team of dedicated Suzuki engineers working with WPSA Pro Motocross Champion Doug Gust.

Powered by a , fuel-injected 450cc four-stroke engine, based on the race proven RM-Z450 four-stroke engine, this ATV is designed to deliver broad, smooth power. With fuel injection, vibration-reducing counterbalancers, a five-speed transmission and electric start. In a low-slung, wide track racing chassis with long-travel suspension, a high-tensile steel swingarm and heavy duty steering stem and rear axles. Complete with an exciting, aggressive new look.

A high-performance, race-ready ATV that inspires rider confidence. On the starting line for a WPSA motocross. Or at a local track on a Saturday afternoon.
