Performance Engine


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:

  • Piston, piston pin and piston ring
  • Camshafts intake valves
  • Cam chain tensioner/adjuster
  • Crankshaft and magneto

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.

Cam Chain

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)

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;

  • It changes ignition map for quicker launch. (Only in launch sequence)
  • It is selectable from two different modes to suit to different conditions.
  • Three-stage control for more detailed control. In the moment of launch, ride over the starting gate, and acceleration, each sequence is different; which requires different engine characteristic for quicker launch. Therefore, we set different maps for each sequence.

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.

RM-Z250 Holeshot

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 Perfect Balance

Model shown: 2016 RM-Z250

Chassis - Main frame

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.

Air Time

Model shown: 2016 RM-Z250

KYB rear shock

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.

PSF2 Front Fork

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.

Other Features

Front ForksModel shown: 2016 RM-Z250

Renthal Fatbar
Renthal Aluminium Fatbar® is standard equipment. It has more strength and less vibration than aluminium straight handlebars.

Brake Caliper

Low weight caliper
The front caliper of the RM-Z means low weight without compromising braking performance.

Rich Coupler

Rich/Lean couplers
For quick fuel adjustment setting to suit riding condition, two couplers are enclosed. One is for rich and another for lean fuel setting compared to stock setting. Customer can change fuel setting to best suit the riding conditions by just connecting either coupler.

Excel Rims

Excel aluminium rims & Dunlop tyres
Excel aluminium rims are made specifically to withstand rugged racing environments, including Supercross, Motocross and off-road conditions. Tyres are the latest MX52 series. MX52 series are designed with CTCS (Carcass Tension Control System) technology for optimised tyre rigidity.
