2009 Suzuki RM-Z450

Chassis

• 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.
• Two-tone molded-plastic radiator shrouDual Sport 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.

Engine

• 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.
• Five-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.
