2012 Suzuki RM-Z450 Review
The 2012 RM-Z450 is an open-class motocross machine that’s ready to dominate the toughest of tracks. As a racer, you need quick, laser-accurate steering and confidence-inspiring high-speed handling all in one package. And you want a high performance machine with a racing pedigree that makes it competitive right out of the crate.
The RM-Z450 has been taking champions across the finish line ahead of the pack for years, fiercely competing across the globe from the World MX1 series to America’s prestigious AMA Supercross and outdoor motocross championships. It-s no secret that Champions Choose Suzuki!
Mount up. Because 1st place doesn-t come without a fight. Razor-sharp handling. Beastly torque. Quick-response braking. They-re not features, they-re the difference between podium and parking lot.
Our legendary RM-Zs put the track-and the competition-at your mercy.
The 2012 Suzuki RM-Z450 is now available and as only can be expected from this championship-winning motorcycle, it is 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.

Suzuki’s class-leading fuel-injection system uses technology derived from Suzuki’s championship-winning models. The RM-Z450, the first motocross bike to ever use fuel injection, has won both outdoor championships as well as a Supercross championship.
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.
