Suzuki Presents Ultimate Race-Ready ATV –
All-New QuadRacer R450 is Suzuki’s Newest Jewel

Brea, Calif. (October 3, 2005) – Suzuki introduces a brand-new, race-ready sport ATV to its award-winning fleet. The 2006 QuadRacer R450 is built for the track with proven Suzuki racing technology, eye-catching design and awesome power.

Suzuki has a rich history of designing championship-winning products from its hugely successful GSX-R sportbikes to its famed RM and RM-Z motocross lines. Lessons learned on the track have led to the creation of the QuadRacer R450, named after the original QuadRacer LT250R — introduced 20 years ago as the first high-performance sport quad on the market.

But the legend stops there, and starts anew with the help of Doug Gust, multi-time ATV MX Champion and member of Team Suzuki Yoshimura ATV racing. Gust spent time with the engineering and design team responsible for the new QuadRacer, visiting the headquarters in Hamamatsu, Japan, and riding on the test track there with other test team members. Gust’s experience as a leading motocross racer was invaluable to the project, and the results are felt in the machine’s winning performance.

The QuadRacer’s powerful engine is derived from the championship-winning RM-Z450 motocross machine. The 450cc liquid-cooled engine has a compact design and features an awesome spread of power with maximum durability and a lightweight, advanced fuel-injection system.

The QuadRacer’s EFI system is highlighted by its multi-hole injector and 42mm throttle body. The system is more responsive and more efficient than a traditional carburetor, and it’s lighter, too.

The QuadRacer R450 comes complete with a new dry sump system that divides the crankcase into two internal compartments, creating a lower center of gravity and shorter overall engine height for improved handling. The 450’s specially designed engine utilizes three oil pumps for a more compact and durable system with better shift-feel for the rider.

The new sport quad boasts an all-new five-speed transmission, with gears located inboard to keep it very compact. The narrow transmission also allows the clutch to be positioned close to the centerline for optimum mass centralization and improved handling performance on the track.

Also unique is the all-new, center-mounted, stainless-steel exhaust system. Designed for maximum performance, it features a centrally located muffler to improve stability and create optimum handling performance through those rough corners, giving racers the edge.

The chassis was built with the motocross track in mind and provides superb handling, awesome stability and maximum durability. The frame features a high-tensile steel construction with a compact, lower profile and a lower center of gravity for inspired handling and performance.

Front suspension is all new with a freshly designed independent double wishbone system with long wheel travel and a low center of gravity. The ultra-wide A-arms feature steel round tube construction on both upper and lower A-arms with a forged aluminum knuckle for maximum strength.

The front wheels are 10 x 5.5 inches shod with Dunlop radial tires designed specifically for the R450. The special Dunlop tires also are mounted at the rear on 8 x 8.0 pressed-aluminum alloy wheels. The combination of both sets of new pressed-aluminum wheels and special Dunlop tires creates an aggressive and low-handling package for maximum performance that the QuadRacer R450 owner demands.

The QuadRacer R450 doesn’t get by on mechanics alone. It’s got the looks of a winner with a T-shaped seat, sharply styled fenders, a newly designed multi-reflector headlight, aggressively styled radiator shrouds, stylish fuel tank covers and side panels and a maintenance-free LED taillight that boasts minimal weight, compact design and maximum durability.

The all-new QuadRacer R450 has been created to be the most race-ready high-performance sport ATV on the market, offering Suzuki customers a machine designed for the track with little or no modifications necessary.
