From the dealer's page
The 2021 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 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 2.0 or proven fuel-coupler system that is included with each 2021 RM-Z450.
