2015 Suzuki RM-Z450
The Suzuki RM-Z450 has been revamped for 2015 with an air fork that is lightweight and now features launch control. An evolution of the RM-Z’s Separate Function Fork (SFF) tech, the new Suzuki fork swaps the conventional metal spring for three adjustable air chambers. The standard issue Showa SFF Air Fork delivers more progressive suspension feel and easy adjustment via a handheld pump. Suzuki has redesigned the frame’s downtube and inner ribs to balance rigidity and reduce weight and Suzuki updated de-compression and redesigned the exhaust camshaft, as well as revise the kick-gear ratios to make the RM-Z450 easier to start. The kickstart lever is also 30mm longer, for extra leverage.
Suzuki continues to hone its tried-and-true RM-Z450 motocrosser. Three-time X-Games Gold Medalist Vicki Golden gives us her take.
