2009 Suzuki RM-Z450

Introducing the RM-Z450 with Suzuki fuel injection. Our engineers developed the RM-Z450 using experience gained developing fuel-injection systems for Suzuki's legendary GSX-R road race bikes and the championship-winning QuadRacer R450 ATV.

The result is the world's only mass-produced, fuel-injected motocross bike, designed to help you blow away the competition. As if that breakthrough technology weren't enough, our engineers used their experience developing Ricky Carmichael's championship-winning RM-Z450 to redesign the RM-Z450's chassis, suspension and brakes. That means it offers sharper handling, smoother suspension performance and more powerful braking than ever.

And just so no one misses the fact that you're on the hottest bike on the track, the RM-Z450 is also completely restyled, with new aerodynamic bodywork that's both sleek and functional. The all-new fuel-injected RM-Z450 - it gives you the power to dominate.

Engine Features

• Electronic Fuel Injection offers better roll on power and strong low-to-mid range power. KEIHIN throttle body specifically designed for motocross. Fuel is delivered via an internal fuel pump and is a battery-less system

• 5-Speed Transmission makes the RM-Z450 versatile for various terrain conditions and features a link type shifting mechanism

• Intake port angle and cam timing result in reduced intake resistance and heightened intake efficiency. Exhaust port and cam timing are designed to regulate exhaust pulses for maximum engine performance

• Battery-less fuel injection system features a single-phase all-charging system with which the magneto supplies all of the necessary power

• 18-pin magneto-rotor senses feedback on crankshaft position, rotation speed and stroke which is fed back to the ECU to calculate optimum injection and ignition timings.

• KEIHIN fuel pump located inside the fuel tank provides stable pressure delivery to operate the fuel injection system

• 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

• Semi-dry-sump lubrication system features separate oil chambers for the transmission and crankshaft using the transmission as the oil sump, allowing low crankshaft placement, reduced engine height and a low center of gravity

Chassis Features

• Aluminum-alloy twin spar frame is lightweight and has optimum rigidity balance for incredibly agile handling and unmatched performance over bumps

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

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

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

• Showa-brand rear shock absorber designed to deliver a controlled feel and increased bottoming resistance

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

• Front fender incorporates a sloped-down shape to efficiently guide wind to the front number plate air ducts for improved cooling performance. Rear fender incorporates air intakes on both sides for heighten intake efficiency

• 2-tone molded-plastic radiator shrouds give the RM-Z450 a slim feel and stylish look for 2009 while also complimenting an all-new graphics design and color way

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

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

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

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