Boasting championship-winning technology, the Suzuki fuel-injected RM-Z450 offers exceptional performance across the powerband — complemented by advanced chassis and suspension systems for unrivaled versatility on a variety of tracks.
Details & Features
Engine Features
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.
5-Speed Transmission makes the RM-Z450 versatile for various terrain conditions and features a link type shifting mechanism
Battery-less fuel injection system features a single-phase all-charging system with which the magneto supplies all of the necessary power
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
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
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
KEIHIN fuel pump located inside the fuel tank provides stable pressure delivery to operate the fuel injection system
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
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
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 for incredibly agile handling and unmatched performance over bumps
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 heighten 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 opens up the cockpit for additional room to allow the rider to actively take control of the machine
