Fully re-engineered engine, chassis and electronics, plus dramatic new styling. The result? The most potent, balanced and competitive RM-Z450 yet.
Suzuki poured more than 40 years of open-class racebike engineering into the RM-Z450 to make it the hardest-hitting, sharpest-handling, best-balanced and most rider-friendly production motocrosser in company history. Now get out there and own it.
To give riders an even stronger winning balance, the latest RM-Z450 engine has more low-end torque, a flatter overall torque curve, faster and yet more controllable throttle response, and more peak power.
Light, rigid and agile, the latest Suzuki RM-Z450 gives riders sharper handling, better feel and more control than ever. Its all-new lightweight frame, swingarm significantly improve turning performance, whether you're railing a berm or diving into the inside line.
The Showa Balance Free Rear Cushion (BFRC) shares technology with the GSX-R1000R. The design balances pressure above and below the piston to better control the stroke and smooth out reactions to bumps and chop, even under severe braking.
Showa front and rear suspension delivers improved control, quicker lap times and less fatigue under hard training or racing conditions. Up front, an updated Showa coil-spring fork replaces the SFF-Air fork of the previous-generation RM-Z450.
