The 2010 Suzuki R450 Quadracer All Terrain Vehicle

Suzuki R450 QuadRacer

Having recently been crowned the AMA/ATVA National MX champion, the Suzuki QuadRacer R450 is indisputably the hottest four-wheeler on the track.

Its Suzuki fuel-injected 450cc powerplant offers astounding top-end performance, with a technically advanced chassis and responsive, long-travel suspension so you can conquer the toughest tracks.

Suzuki QuadRacer R450 with 450cc liquid-cooled, single-cylinder, four-stroke engine. This engine features electronic fuel injection with a multihole injector and a 42mm throttle body.

There are a vast number of benefits to an EFI system on a performance quad including the fact that it’s more responsive, efficient, and lighter than a traditional carburetor.

The engine also features three oil pumps; a low center of gravity; and a center-mounted stainless steel exhaust system.

The engine funnels power to an all-new five-speed transmission that features inboard-located gears to keep it very compact. Updates in 2008 made the Suzuki R450 more competitive for track and trail than it was already. It’s a preferred machine for people who spend more time on the track. Compared to other 450s, the Suzuki holds a price advantage for starting a racing hobby.

COOL FEATURE: The suspension is fully adjustable in the front and rear.

SPECIAL OPTIONS: A Limited Edition has black wheels and comes with a red cab and black chassis or black plastics with a gold chassis for $7,799. It’s the best $100 upgrade out there.
