For 2011, the RM-Z450 meets a stricter AMA noise limit (94db) while keeping smooth engine output.
Suzuki's class-leading fuel-injection system uses technology from Suzuki's championship-winning models-the GSX-R motorcycles and the QuadRacer R450 ATV. The RM-Z450, the first motocross bike to ever use fuel injection, has won both outdoor championships as well as a Supercross championship.
The RM-Z450's 449cc four-stroke, liquid-cooled, DOHC, four-valve, fuel-injected engine was developed and refined to deliver phenomenal idle-to-redline thrust.
The RM-Z450's aluminum cylinder is treated with Suzuki Composite Electrochemical Material (SCEM) coating, and was built for durability, light weight and efficient heat transfer.
The RM-Z450's slim chassis design makes for a comfortable riding position, opening up the cockpit to help allow the rider to actively take control of the machine.
The RM-Z450's twin-spar aluminum frame and swingarm was developed and refined for a highly optimized balance between rigidity and superb high-speed traction. The lightweight swingarm helps enhance terrain-traversing performance over bumps.
