Suzuki’s 2010 RM-Z450 Motocross Bike Revised

Suzuki announced that it’s refreshing the motocross line-up, as the RM-Z450 model has undergone thorough revisions for 2010. The Japanese manufacturer improved the engine performance and also brought changes to the chassis which is said to offer laser-accurate steering and high speed stability.

Cam profiles and cylinder-head porting were also revised, offering improved performance across the rev-range. According to europeanmotornews.com, one of the most important change is the improved camchain tensioner, providing more consistent performance as well as a new throttle linkage making low-speed response more progressive.

The 2010 model brings a two-piece design headstock that is 9mm taller than on the previous model, wider rear frame-sections and a wider upper frame bridge. The 2010 RM-Z450 also has smaller updates, including a revised fuel-injection system, featuring a reversed throttle-valve movement, to increase power and throttle response.

RM-Z450’s Showa suspension has also been improved, offering new spring and damping rates front and rear. The 47mm inverted forks offer optimum wheel travel with compression and rebound damping, while the Showa fuel tank shock gives both high-and-low-speed compression damping for an improved overall traction.

“With the recent news of our all-new RM-Z250 and RMX450Z, these significant updates on our flagship model give us an extremely strong range. While the 450 was the first production motocross machine to feature fuel-injection, we believe the changes for 2010 will keep it firmly at the front of the pack,” said Suzuki GB marketing manager, George Cheeseman in a release for the press.

Suzuki announced the bike will be available in dealers later this month, at a recommended retail price of £5,799 ($9,808).
