From the dealer's page

Completely redesigned for 2018, the RM-Z450 wraps a sleek, race-ready appearance around a stronger engine and a nimble chassis that continues the Suzuki tradition of extraordinarily precise handling. Developed using Suzuki’s RUN, TURN and STOP philosophy that creates a Winning Balance, the 2018 RM-Z450 has stronger brakes for better stopping power, a wider spread of engine muscle with higher peak power, and a chassis that is stronger, lighter and more nimble to raise the standard for cornering performance.
