Its fuel injection for '08 Suzuki RM Z450
By TMX Archives on 6th Jul 07
SUZUKI is set to launch its exciting, uprated 2008 RM-Z450 and the Japanese factory is breaking new ground as the model will be the first production MXer to be fitted with fuel-injection!
In fact there will be a host of new features including:
Electronic Fuel Injection which is claimed to offer better roll-on power and improved low-to-mid range power with a Keihin throttle-body specifically designed for motocross. Fuel is delivered via an internal fuel pump and the bike uses a battery-less system.
Five-speed transmission makes the RM-Z450 more versatile for various terrains and features an all new link type shifting mechanism.
Intake port angle and cam timing are revised and result in reduced intake resistance and heightened intake efficiency. Exhaust port and cam timing are designed to regulate exhaust pulses for maximum engine performance.
Flywheel inertia increased to produce a smoother revving engine and improve overall acceleration feel.
Airbox is constructed as a separate unit which is sealed by a lid to prevent air leakage and improve overall intake efficiency.
Keihin fuel pump located inside the fuel tank provides stable pressure delivery to operate the fuel injection system.
Redesigned combustion chamber for better power output and improved low-to-mid range response. Narrower intake and exhaust valve angle guides along with increased squish areas improve air/fuel mixing and faster flame-propagation speed when mixture ignites.
Chassis:
All-new frame is lighter and has improved rigidity balance for incredibly agile handling and unmatched performance over bumps.
Slim riding position 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 rear shock absorber with a newly designed damper case and modified internal structure for a better controlled feel and increased bottoming resistance.
Redesigned rear swing arm. Thinner wall thickness swingarm to reduce weight and improve performance over bumps.
