2023 Suzuki RM-Z450

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.
