Those who have been saying that Suzuki is losing ground in the off-road field can start eating their words (at least partially) because the Japanese manufacturer has launched an all-new model for 2010 – the RMX450Z. Based on the RM-Z450 competition model, the new addition is a slightly more docile four-stroke dirt bike to take both on the track and on the trails. It retains the 450cc engine and brings the benefits of electric starting and those of a headlight out where Suzuki riders would have previously struggled with the DR-Z400S . Bikes such as the Honda CRF450X , Yamaha WR450F and Kawasaki KLR450R can already start worrying.

Suzuki Takes Covers Off All-New RMX450Z
Suzuki is excited to announce the introduction of the all-new 2010 RMX450Z competition-specific enduro racer to its product line up.
Set to arrive in Australia late this year, the RMX450Z shares the DNA of Suzuki’s championship winning RM-Z450 motocrosser, including a fuel-injected 449cc engine, and race-bred frame, suspension and bodywork.
Developed to maximise off-road performance, the new model heads Suzuki’s popular off-road range, which includes the street-legal DR-Z400E.
’The introduction of the 2010 RMX450Z adds some serious firepower to Suzuki’s off-road line-up," Perry Morison, General Manager, Motorcycles, Suzuki Australia said.
’It takes advanced technology developed by Suzuki in motocross competition, and puts it into a race-ready enduro package.
’The RMX450Z features the same 449cc fuel-injected engine that revolutionised motocross in the Suzuki RM-Z450, along with a host of other common components - it’s a high-spec off-road weapon."
Delivering exceptional power and torque, the RMX450Z is powered by a 449cc, four-stroke single-cylinder, liquid cooled, DOHC, 4-valve engine, sharing the key technologies of the RM-Z450.
Utilising Suzuki’s vast experience and knowledge on and off-road, the Electronic Fuel Injection (EFI) system ensures crisp and strong power delivery, lower emissions and impressive fuel economy.
A modified inlet tract and revised cam profiles enhance low and mid-range power, while the airbox features a hinged lid for quick air filter access, easier maintenance and better dust protection.
To meet the demands of trail riding, the RMX450Z has an extra coolant reservoir tank and relocated filler cap, along with a bash plate.
Wider primary and final drive ratios in the five-speed transmission help riders get the most from the impressive engine when off the beaten track, from tackling a rutted uphill goat track to open fire roads.
The trail is no place to be kick-starting, and the RMX450Z features an electric starter, while the starter and lights’ centrally-located batteries are charged by a larger magneto-generator.
Based on the RM-Z450 but optimised for off-road riding, an aluminium alloy frame utilises cast and extruded sections in a slim, lightweight, rigid and tough package.
The RMX450Z features a Showa suspension package derived from the championship winning RM-Z450 - the 47mm inverted front forks are fully adjustable for rebound and compression settings, while the rear shock unit offers fully adjustable rebound, compression and pre-load settings.
Spring rates and suspension geometry on the Suzuki have been developed for off-road riding, combining with an 18 inch rear wheel to offer razor-sharp cornering and a smooth ride across rugged terrain.
Slim bodywork, a low-profile aluminium fuel tank and a motocross-developed seat gives RMX450Z pilots a functional riding position to focus on the terrain ahead to optimise line selection.
The RMX450Z’s compact instrumentation offers riders the choice between two modes, a sports mode showing the basic information a rider needs in competition, such as a trip meter, timer and average speed, while a standard mode displays additional information including speed, time and information of two trip lengths.
An integrated tyre diameter calculator allows precise fine tuning for different tyres, giving racers accurate live data for speed and distance displays.
Suzuki’s trademark Black / Champion Yellow livery with black, white and red graphics accompanies the aggressive styling of the class-leading RMX450Z.
