2010 Suzuki RM-Z450 and new RMX450Z revealed

Suzuki Australia releases revamped 2010 model RM-Z450 motocrosser as RMX450Z breaks cover for release later this year.

Suzuki has revealed two new dirt bikes today in the revamped 2010 model RM-Z450 and the all-new RMX450Z enduro racer, set to boost the manufacturer into the off-road market.

In an early release, the RM-Z450 motocross model is already available in Australia, with the RMX450Z announced overnight in Great Britain and scheduled to arrive in Australia late in 2009.

Two years after revolutionising the motocross world with its fuel-injected engine, Suzuki’s championship-winning RM-Z450 motocrosser has raised the bar again, with the new 2010 model boasting a host of upgrades.

In 2007, the RM-Z450 became the world’s first production motocross motorcycle to feature electronic fuel-injection, a ground-breaking move which has seen Suzuki lead race fields across the globe.

With Steve Ramon at the helm, the fuel-injected RM-Z450 won the 2007 team and rider titles in the competitive FIM MX1 Motocross World Championship.

The RM-Z450 is also Chad Reed’s weapon of choice, the Australian superstar currently leads the AMA Motocross Championship, having dominated last year’s inaugural Australasian Supercross Championship and scored regular race wins in this year’s AMA Supercross Championship.

With other manufacturers still playing catch up, the new 2010 model has received a range of significant upgrades, including a further improved engine, a new frame and new suspension, set to keep the Suzuki RM-Z450 at the front of the field.

“Suzuki’s RM-Z450 led the way with fuel-injected technology in motocross racebikes; it changed the face of the sport,” Perry Morison, General Manager, Motorcycles, Suzuki Australia said.

“On and off the track, other manufacturers have followed our lead, and the
2010 Suzuki RM-Z450 is here to move the goalposts again. It’s Suzuki’s best motocrosser yet, with major engine, chassis and suspension developments, and is ready to continue the winning ways of the RM-Z450.”

Further enhancing throttle response and power throughout its rev range, the 449cc, four-stroke, single-cylinder, liquid cooled, DOHC, 4-valve engine features a new cylinder head, piston, crankshaft, throttle body, cam shafts and valve springs.

Pioneered by Suzuki, the Electronic Fuel Injection (EFI) system is even better with a reversed throttle valve movement, directing mist away from the valve to produce more power and enhanced throttle response.

The perfect match for a potent engine, 2010 RM-Z450 riders will benefit from significant chassis and suspension development.

A new, more rigid, twin-spar aluminium frame is accompanied by a new subframe, linkage and rear swingarm, and enhanced, race-bred Showa suspension to help provide sharper handling, improved manoeuvrability and maximum traction.

With revised spring and damping rate settings at each end, 47mm inverted front forks are fully adjustable for rebound and compression settings, while the rear shock absorber offers fully adjustable rebound, compression and pre-load settings.

The new RM-Z450 also features a new radiator and significant electrical upgrades including ECU revisions, as part of the ultimate motocross weapon.

Now available in Australia, Suzuki 2010 RM-Z450 sports an aggressive look, with bold new graphics adorning Suzuki’s traditional Champion Yellow livery.

News has also come through overnight that Suzuki will be launching a new 2010 model RMX450Z enduro machine that will spearhead the manufacturer’s off-road campaign.

The all-new RMX450Z is based on Suzuki’s RM-Z450 motocross model, but features a revised enduro-spec engine and electric start, while also retaining the fuel injection system used on the motocross model.

Suzuki’s new off-road weapon will also differ from the motocross model by featuring revised suspension settings, an 18-inch rear wheel, a lighting system, side stand, standard sump guard and a digital instrument panel. spoke with Suzuki Australia today and confirmed the model will be available in late 2009, but it won’t be ADR compliant for 2010 as Suzuki will monitor the potential of the model first due to the current economic climate and the cost of compliance modifications for an Australian specification model.

More, from a Suzuki Australia press release:

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 Australia’s best seller to date in 2009, the street-legal

“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.

The brand-new, 2010 Suzuki RMX450Z will be available in Australia in late 2009.

Whilst Suzuki Australia understands strong market demand for this model, the 2010 RMX450Z will not be certified as a road going motorcycle.

The high cost of engineering to achieve ADR compliance in the current economic climate means a street-legal version is commercially unviable, however, Suzuki Australia will continue to evaluate its potential development moving forward.
