The 2010 RM-Z450, a thoroughly updated, cutting-edge open-class motocrosser thats more potent than ever.


Across-the-board engine upgrades boost power from awesome to awe-inspiring. Detailed frame and suspension modifications improve an already sharp-turning racebike. Featuring Suzuki's electronic fuel injection with revised throttle valve movement increases overall power making the RM-Z an even more potent weapon for this 2010.


Ground breaking performance from a ground breaking machine. The RM-Z450 has the goods that deliver from the drop of tha gate to the checkered flag.

Gold-colored chain and axle blocks give a full factory look


Aluminum-alloy swingarm for reduced weight and maximum terrain-traversing performance over bumps


Footpegs include maximum clearance between the mounting bracket and footrest to prevent mud from caking up


Race inspired brake rotors provide better cooling performance and increased mud deflection in muddy conditions


Showa cartridge-style front fork is fully adjustable for rebound, compression and preload settings and designed for reduced weight and improved shock absorption


Combustion chamber designed for strong low-to-mid range response as well as top-end pull. Narrower intake and exhaust valve angle guides along with increased squish areas improve air/fuel mixing and faster flame-propagation speed when mixture ignites


2-tone molded-plastic radiator shrouds give the RM-Z450 a slim feel and stylish look while also complimenting an all-new graphics design and color scheme


Electronic fuel injection provides more acceleration power at low and medium rpm


Slim riding position opens up the cockpit for additional room to allow the rider to actively take control of the machine


Aluminum fuel tank houses a KEIHIN fuel pump for optimum performance and a factory bike look


Hot start lever is located on the right hand side of the handlebar for easy operation while holding the clutch
