The suggested MSRP for the 2009 RM 450 is $7,899

It’s engine features include:




An 18-pin magneto-rotor that senses feedback on crankshaft position, rotation speed and stroke. This iis fed back to the ECU to calculate optimum injection & ignition timings




Five speed gearbox




It’s one of the few bikes on the race track with fuel injection that features a single-phase, all-charging system – the magneto supplies all of the power required




The 2009 Suzuki RM 450 combustion chamber has been designed for strong low-to-mid range, as well as top-end pull. Narrower intake & exhaust valve angles. Cylinder squish areas improve air/fuel mixing and faster flame propagation speed




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




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




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




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






It’s chassis features include:




Two-tone molded-plastic radiator shrouds give the 2009 Suzuki RM-Z450 a slim feel and stylish look, while also complimenting an all-new graphics design




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




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




Aluminum-alloy twin spar frame is lightweight, and has optimum rigidity balance




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




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 heightened intake efficiency




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




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




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




Slim riding position allows the rider to control the bike effectively
