The 2023 RM-Z450 remains the champion’s choice, as its sleek, race-ready appearance, strong engine, and nimble chassis continue the Suzuki tradition of extraordinarily precise handling.

The RM-Z450 epitomizes Suzuki’s “Winning Balance” philosophy of "RUN, TURN, and STOP" with strong brakes for controlled stopping power, a wide spread of engine muscle with high peak power, and a strong, light, and more nimble chassis that remains the class standard for cornering performance.

Tuning the electronic fuel injection and ignition systems for maximum performance is easy thanks to Suzuki’s smartphone-based MX-Tuner and proven fuel-coupler system that is included with each 2023 RM-Z450.

• Included with the 2023 RM-Z450 is Suzuki’s MX-Tuner 2.0 that provides the ability to easily adjust the fuel injection and ignition system settings for optional race performance.
• Suzuki’s proven, easy-to-use fuel couplers are also included to simplify EFI tuning. For quick fuel adjustments to suit riding conditions, two couplers are provided. One is for a richer-than-stock and another for a leaner-than-stock fuel setting. Riders can change fuel settings in seconds by simply connecting either coupler to the wire harness.
• The RM-Z450 features an evolved and efficient traction management system. The Electronic Control Module (ECM) continually measures throttle opening, engine speed, and gear position and then adjusts the ignition timing and fuel injector duration to fine-tune the engine output to deliver the best traction for the riding conditions.
• The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help the rider's takeoff from the starting gate for an early lead. There are three launch modes riders can choose for the best option per their skill level and starting conditions. There are also three stages to Mode A and Mode B of the S-HAC system. This helps riders at the moment of launch, when crossing the gate, and through acceleration to the full speed. The S-HAC settings for Mode A on the RM-Z450 are specially tuned to aid the rider’s throttle control during launches.
• Mode A: For hard surfaces or slippery conditions at the starting gate. In this mode, S-HAC alters ignition timing at the moment of launch and the ride over the gate to reduce wheel slip to deliver a smooth takeoff. It also advances ignition timing during this sequence for stronger acceleration. After six seconds or when you reach fourth gear, the system shuts off and returns to normal ignition timing. Benefit of Mode A: For novice riders, and/or hard and slippery traction conditions, use Mode A for a more controlled launch
