The Ultimate Fuel Injected 4-Stroke Weapon

The world's first-ever mass produced fuel-injected motocross machine, the ground-breaking Suzuki RM-Z450 is the weapon of choice for motocross riders.

Suzuki opened the door to a whole new era in motocross design with the introduction of the revolutionary new RM-Z450 fully equipped with advanced fuel-injection technology.

Enhanced throttle response and power throughout its rev range, the 449cc, four-stroke, single-cylinder, liquid cooled, DOHC, 4-valve engine features the latest cylinder head, piston, crankshaft, throttle body, cam shafts and valve springs.

Pioneered by Suzuki, the Electronic Fuel Injection (EFI) system is even better with a reversed throttle valve movement, directing mist away from the valve to produce more power and enhanced throttle response.

The perfect match for a potent engine, 2010 RM-Z450 riders will benefit from significant chassis and suspension development. A new, more rigid, twin-spar aluminium frame is accompanied by a new subframe, linkage and rear swingarm, and enhanced, race-bred Showa suspension to help provide sharper handling, improved manoeuvrability and maximum traction.

With revised spring and damping rate settings at each end, 47mm inverted front forks are fully adjustable for rebound and compression settings, while the rear shock absorber offers fully adjustable rebound, compression and pre-load settings.

Built with lessons learned from racetrack domination, Suzuki's ultimate weapon is ready for launch.
