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 249cc, 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-Z250’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.
Low crankshaft weight means reduced friction from oil agitation, while higher magneto rotor inertia weight allows a balance to be retained.

The cam chain tensioner is Teflon coated to reduce friction and increase durability. The design of the tensioner adjuster ensures a good range of adjustability.
Suzuki Holeshot Assist Control (S-HAC) is a selectable launch mode 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. 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.
S-HAC helps the rider in launching from starting gate for an early lead. It was introduced in 2014 with RM-Z450, now it is standard equipment on RM-Z250 with more advanced, detailed control.
The steering head pipe design of the RM-Z250 mirrors that of the RM-Z450. This along with the rib structure on the inside of the pivot parts and lower connection mean frame weight is minimised and chassis rigidity is optimised. All this culminates in the trademark great cornering performance of the RM-Z.
The KYB rear shock features integral adjuster system. That provides easy access to adjusters, rebound damping and compression damping High & Low speed are adjustable with the integral adjuster. While the cushion rod spacer shape allows for optimum absorption feeling.
The RM-Z250 comes with PSF2 front fork, the latest version of KYB’s Pneumatic Spring Fork. It weighs less than a conventional spring fork, and adjusting the spring rate is as easy with pumping air. Thanks to no-coil spring design, damper cylinder is enlarged. It results in greater damper response and more stable damper performance. Its high/low-speed compression and rebound-damping adjustments let you dial it in any track with ease.
