"Fuel-injection technology has revolutionised motocross racing following its introduction on the Suzuki RM-Z450 two years ago," Perry Morison, General Manager, Motorcycles, Suzuki Australia said.
"Now, Suzuki is set to lead the pack again with the all-new 2010 RM-Z250, the first production motocrosser in its class with a fuel injected engine."
Now revving to 13,500pm, the new RM-Z250 features a 249cc, four-stroke, single-cylinder, liquid cooled, DOHC powerplant.
Pioneered on the RM-Z450, Suzuki's Electronic Fuel Injection (EFI) system incorporates a 43mm throttle body with progressive throttle linkage and a battery-less fuel pump.
The engine features titanium valves, an aluminium-alloy cylinder, with Suzuki's Composite Electrochemical Material (SCEM) cylinder coating, and Suzuki Advanced Sump System (SASS).
Suzuki says revised cam timing and intake ports have enhanced high-rpm performance, without compromising impressive low-to-mid range power and torque.
Radiator louvers have been re-designed, directing more air to the twin, side-mounted aluminium alloy radiators.
The Suzuki is also fitted with a new muffler.
The RM-Z250 has a five-speed transmission and a right-handlebar-mounted hot starter.
The Suzuki RM-Z250 has an updated chassis and suspension system, plus a redesigned lightweight twin-spar aluminium-alloy frame.
Suzuki's 2010 RM-Z250 will be available in late 2009.
