2010 Suzuki RMX450Z

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 rider 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 tire 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.
Engine Features
•  The trail is no place to wear yourself out kick-starting a bike, so the RMX450Z comes with an electric starter, energized by a compact battery centrally located to reduce its influence on weight distribution and balance of the bike. To charge the battery and power the RMX450Z’s lights, a larger magneto-generator is fitted. It’s a win-win situation.
Fuel Injection
Fuel Injection
•  Suzuki pioneered fuel injection for motocrossers, and the RMX450Z shares all key technologies with the stunning RM-Z450. Fuel injection improves fuel efficiency, throttle response and reduces emissions, allowing the RMX450Z to be “green sticker” eligible in the state of California. On the every trail in the world, the RMX450Z’s fuel injection provides unmatched smoothness of power delivery and trail-ready reliability thanks to a KEIHIN throttle body with progressive linkage. This advanced fuel injection system also eliminates the need for re-jetting at higher elevations. To best suit the RMX450Z to life on the trail, the airbox features a hinged lid for quick air-filter maintenance and better protection from dust. Suzuki’s vast experience with motorcycle fuel injection both on and off-road help make this among the best systems available.
•  Suzuki has made minimal modifications to the all-conquering RM-Z450’s potent four-valve, DOHC engine for the RMX450Z. This lightweight engine now features a modified inlet tract along with revised cam profiles to increase low and mid-rpm power. Wider gear ratios in the 5-speed constant-mesh transmission that work with revised primary and final-drive ratios are ideally suited for a broad range of conditions, from scaling steep trails to high-speed open-terrain riding. The addition of a coolant reservoir tank increases on-trail reliability, while a relocated filler cap improves access. Because the trail can be a rocky place, a new engine protector plate is fitted. No stone was left unturned.
•  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

•  Sit on an RM-Z450. Now go sit on the new RMX450Z. Feels just about the same, right? That’s right. With an ideal riding position resulting from the motocross-developed seat, slim bodywork and low-profile aluminum alloy fuel tank, the RMX450Z allows the rider to concentrate on the terrain. A comfortable rider is a fast rider.
•  A durable, ultra-compact enclosure houses a full-function instrument cluster on the RMX450Z—and can be configured for two modes, standard and sport . The sport mode simplifies the display so the rider can concentrate on terrain; it shows the timer, tripmeter, average speed and tire-diameter correction. In the standard mode, the display also shows speed, time, two trip lengths, and voltage. An integrated tire diameter calculator allows precise fine tuning for different tires to ensure accuracy of the speed and distance displays. The RMX450Z also features a low fuel level warning light for confident off-road riding anywhere you go.
•  Suzuki’s light and effective aluminum alloy twin-spar frame construction is used in the RMX450Z, employing both cast and extruded sections for the utmost benefits of both: low weight, high rigidity, and high durability. The RMX450Z’s aluminum alloy swingarm is derived from the RM-Z450’s to maintain ideal balance, while the rear suspension linkage benefits from reduced free play. Its geometry combines the RM series’ renowned turning-on-rails abilities with optimized handling performance that all serious trail riders want.
•  Derived from the RM-Z450, the RMX450Z’s trail ready suspension features the same phenomenal action as the race bike. The RMX450Z suspension utilizes high performance rebound and compression damping adjustable Showa forks combined with a Showa piggyback reservoir style rear shock featuring two-way adjustable compression damping with adjustable rebound damping and preload adjustments. Spring rates have been optimized for off-road riding. Every aspect of the RMX450Z’s performance envelope has been carefully considered for serious off-road riding without compromising a millimeter of quality.
•  Footpegs include maximum clearance between the mounting bracket and footrest to prevent mud from caking up
•  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
•  Slim riding position opens up the cockpit for additional room to allow the rider to actively take control of the machine
