2012 Suzuki RM-Z450 Manual

For 2012, Suzuki has a couple of surprises up its sleeve, starting with the RM-Z450 dirt bike. Whereas it would’ve been perfectly fine for the Japanese bike maker to stand pat with their models, they still did its customers a favor by bringing a model that comes with aesthetic, suspension, and engine upgrades. After all, with history attached to its name as the first motocross bike to ever use fuel injection on its way to winning both outdoor championships and Supercross championships, the RM-Z450 deserves nothing but the best. The first of these enhancements involves the use of a new twin-spar aluminum frame and swing arm that was developed and refined for a highly optimized balance between rigidity and superb high-speed traction. 

The lightweight swing arm of the RM-Z450 also helps to enhance the bike’s terrain-traversing performance over bumps while race-inspired disc rotors offer enhanced cooling performance and efficient mud slinging. Finally, the RM-Z450 also comes with a gripper seat that has been designed with projected cross-shaped patterns on the top surface to provide additional grip. The other change on the bike is the front and rear suspension, particularly the use of Showa separate function forks whereas its competitors, particularly Honda, Yamaha Yamaha , and Kawasaki now just use the Kayaba pneumatic spring on the shock breaker. The new front suspension also has a lighter weight and a better absorbing system. Finally, the RM-Z450 is powered by a 449cc, 4-stroke, liquid-cooled, single cylinder, DOHC engine with an upgraded fuel injection system that, in turn, improves on its ECU in controlling the fuel flow to the injector.
