Electronic fuel injection for improved response. 5-speed transmission for smoother acceleration. Corner-railing, whoops-blazing chassis featuring a twin-spar frame built with racing feedback. The 2008 RM-Z450 - ready to revolutionize, with performance, technology, flexible usability, and the Winning Balance.
RM-Z450 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 wave 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.
