The Ultimate Fuel Injected 4-Stroke Weapon

The world's first-ever mass produced fuel-injected motocross machine, the ground-breaking Suzuki RM-Z450 is now available in Australia.

Suzuki has opened the door to a whole new era in motocross design with the introduction of the revolutionary new RM-Z450 fully equipped with advanced fuel-injection technology.

Drawing on the expertise gained with race-bred fuel-injection systems for the legendary Suzuki GSX-R road race machines and the championship-winning QuadRacer 450 ATV, Suzuki has now applied leading-edge engineering technology to the new RM-Z450.

Suzuki engineers have also used experience from developing Ricky Carmichael's championship-winning RM-Z450 to redesign the current model's chassis, suspension and brakes, offering sharper handling, smoother suspension performance and more powerful braking.

Powered by a 449cc, four-stroke, single-cylinder, liquid cooled, DOHC, 4-valve engine, the RM-Z450 features an all-new Electronic Fuel Injection (EFI) system which offers better roll on power and improved low-to-mid range power.

The 2009 RM-Z450 incorporates a battery-less internal fuel pump system which provides stable pressure delivery to operate the fuel injection and utilises a 43mm Keihin throttle body specifically designed for motocross.

The all-new, five-speed, constant mesh transmission on the RM-Z450 offers greater versatility and features a new link-type shifting mechanism.

The latest version of Suzuki's flagship motocross machine features an all-new, lighter frame with a new slim riding position, creating additional room for the rider to manoeuvre and actively take control of the machine.

Offering improved shock absorption with minimal weight, the Showa cartridge-style front forks are fully adjustable for rebound and compression settings, while the new Showa rear shock absorber has a re-designed damper case, modified internal structure and fully adjustable rebound, compression and pre-load settings.

Race-inspired, disc-brake wave rotors deliver better cooling performance and increased mud deflection, while newly-designed pegs have increased clearance between the mounting bracket and footrest to prevent mud from caking up.

Finishing the package, Suzuki's completely restyled RM-Z450 has hot new looks, with sleek, aggressive, aerodynamic bodywork, an edgy, new graphics design and a gold-coloured chain for a full factory look.

Built with lessons learned from racetrack domination, Suzuki's ultimate weapon is ready for launch.

Features

• 449cm3 4-stroke liquid-cooled DOHC engine featuring the first fuel injection on a production motocross bike.

• The fuel-injection system uses technology from Suzuki's championship-winning models - the GSX-R supersport bikes and the QuadRacer R450 ATV.

• The innovative lightweight battery-less electronic fuel injection system brings about better "roll-on" power and responsive low-to-mid range.

• KEIHIN throttle body built specifically for the motocross environment. Progressive throttle linkage improves controllability and efficiently puts the power at low throttle.

• 18-pin magneto senses feedback on crankshaft position, rotation speed and stroke for the ECU to calculate optimum injection and ignition timings.

• Single-phase all-charging system, with the magneto supplying all the necessary electric power.

• Suzuki Advanced Sump System (SASS) with separate crankshaft and transmission compartments allows a highly compact, short and low-slung engine.

• Suzuki Composite Electrochemical Material (SCEM) cylinder coating improves heat transfer, durability and weight reduction.

• 5-speed transmission provides extra flexibility for various terrains and conditions.

• Link-type shifting system offers smooth transitions through the gears.

• Hot starter positioned on the right handlebar, helping allow rider's left hand to focus on clutch operation.

• Slim chassis design while opening up the cockpit for additional room to allow the rider to actively take control of the machine.

• Lightweight twin-spar aluminum frame incorporates racing feedback to deliver corner-railing, whoops-blazing performance and agile handling on various terrains.

• Inverted twin-chamber SHOWA front forks and piggyback-reservoir SHOWA rear shock absorber, both designed focused on lightweight and better shock absorption.

• Lightweight rear swingarm to reduce weight and enhances terrain-traversing performance over bumps.

• Race-inspired disc rotors offer better cooling performance and more efficient mud slinging, compared to traditional round disc rotors.

• Factory aluminum fuel tank. Better fuel efficiency offered by fuel injection allowed a reduced, 6.2-liter tank capacity.

• Footpegs include increased clearance between the mounting bracket and footrest to prevent mud from caking up.

• Stylish front number plate, front and rear fenders, radiator shrouds and louvers add to the fresh 2008 look while improving cooling airflow.

• Gripper seat, with projected cross-shaped patterns on top surface to provide additional grip.

• Factory gold-colored chain adds the finishing touches to the RM-Z450.
