Your Competitive Edge Just Got That Much Better

In exciting news for budding motocross and supercross riders, the 2011 model of the championship-winning Suzuki RM-Z450 is now available in Australia, ready to race right out of the crate.

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

The 449cc, four-stroke, single-cylinder, liquid cooled, DOHC, 4-valve engine features the latest cylinder head, piston, crankshaft, throttle body, cam shafts and valve springs.

Pioneered by Suzuki in the motocross category, the Electronic Fuel Injection (EFI) System uses a reversed throttle movement, which directs mist away from the valve to produce more power and enhanced throttle response.

The RM-Z450’s rigid, twin-spar aluminium frame is accompanied by an advanced subframe, linkage and rear swingarm, whilst the race-bred Showa suspension provides sharp handling, improved manoeuvrability and maximum traction.

This potent powerplant also features a five-speed, constant mesh transmission and impressive brakes package to produce a race-winning package.

Built with lessons learned from racetrack domination, Suzuki's ultimate weapon can now be yours.

Features

NEW FEATURES:

• Meets AMA noise limit (94dB/A) & FIM (115 dB/A) and improve performance:

�– Meets 94db AMA & FIM (115 dB/A) race regulation while keeping smooth engine output.

�– Compression ration has been increased from 12.2 to 12.5 for higher output. �– Intake & Exhaust cam timing has been changed for better engine feeling with lower noise (94db).

�– ECU settings have been updated for more linear acceleration and improved over-rev.

• Easier maintenance:

�– Two optional couplers come with the unit to change the carburetion setting (Richer & Leaner)

�– Convenient fuel line cap for regular maintenance.

KEY 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 position 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.
• Lightweight rear swingarm to reduce weight and enhances terrain-traversing performance over bumps.
• Inverted twin-chamber SHOWA front forks and piggyback-reservoir SHOWA rear shock absorber, both designed focused on lightweight and better shock absorption.
• Race-inspired disc rotors offer better cooling performance and more efficient mud slinging.
• Factory aluminum fuel tank. Better fuel efficiency offered by fuel injection allowed a reduced, 6.2-litre tank capacity.
• Foot pegs 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 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.
