The winning balance

Success on the race track requires a powerful start and strong riding performance throughout every lap. A successful race bike is more than just a strong motor, a great chassis and controlled suspension. It takes a Suzuki RM-Z450 and the winning balance.

449cc Engine

The fuel-injected 449cc four-stroke powering the Suzuki RM-Z450 packs the right combination of dirt-slinging torque and arm-stretching horsepower. And for today’s riders, the engine does even more, thanks to a mix of new technology and proven engineering. 

Rich/Lean Couplers

Cooling Performance


The steering head pipe design of the RM-Z450 mirrors that of the RM-Z250. 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.

Showa SFF Air Fork

The Showa Separate Function Fork (SFF)-Air Front Fork, tested and proven by factory racers, is standard equipment on the RM-Z450. Eliminating the heavy coil spring from the right side fork, the SFF-Air Fork uses air – lightweight and microadjustable – to deliver a higher level of performance.

KYB rear shock

The KYB rear shock features integral adjuster system. That provides easy access to adjusters, rebound damping and compression damping (High and Low speed) are adjustable with the integral adjuster. While the cushion rod spacer shape allows for optimum absorption feeling.

Waved disc rotors

The waved shape of the brake discs are standard on the RM-Z450, designed to minimise weight. Also staying cool and clean through a day of tough racing.

Excel aluminium rims

Excel aluminium rims are made specifically to withstand rugged racing environments, including Supercross, outdoor Motocross and off-road conditions. The aluminium-alloy rims are designed and shaped to stay strong and to maintain their good looks.

S-HAC controller


Suzuki Holeshot Assist Control

A selectable launch mode system derived straight from factory race bikes. S-HAC helps riders in launching from the starting gate for an early lead.
