To ensure optimum performance, particular attention has been paid to the following areas, to hone and perfect their design and performance over the years to bring you the best RM-Z possible:
The 449cc, 4-stroke, fuel-injected, DOHC engine, with a compact and lightweight design, packs the right combination of dirt-slinging torque and arm-stretching horsepower, which powers the RM-Z450’s championship-winning performance. And for today’s riders, the engine does even more, thanks to a mix of new technology and proven engineering. The engine design means easier starting, more consistent launch off the line, and a smoother spread of torque and horsepower to make the bike more exciting to ride – and easier to ride to victory.
Starting the RM-Z450 has never been easier, with consideration paid to every component in the process, using feedback from our race teams around the world. The extra-long kick start gives great ergonomics for the rider, and has a long swing to minimise the effort required.

Cooling efficiency is maximised to ensure optimal engine output, utilising simple and direct hose routing with y-shaped connectors.
Suzuki Holeshot Assist Control (S-HAC) is a selectable launch modeâ€¨ system derived straight from factory race bike. The basic idea of Suzuki Holeshot Assist Control (S-HAC) is as follows;
S-HAC has two selectable modes so riders can choose the best option for the starting conditions.â€¨For hard surfaces or slippery conditions at the starting gate, choose A-Mode. In this setting, Holeshot Assist Control alters ignition timing in moment of launch and ride over the gate to reduce wheel slip and to deliver smooth launch, and it advances ignition in the acceleration sequence for stronger acceleration. Then one of three conditions will return the ignition to normal operation: after 6 seconds from start; when you shift to fourth gear; or when the throttle is closed (whichever happens first). When conditions at the starting gate provide better traction, and a more aggressive launch is needed, choose B-Mode. For these conditions, Holeshot Assist Control advances ignition timing to allow increased throttle response and stronger acceleration off the line. But level of ignition advance is optimised for each three sequence. The system returns the normal ignition map by same conditions of A-mode.
