Key Features

  • 49mm SHOWA SFF-Air TAC Fork
    49mm SHOWA SFF-Air TAC Fork

    The most advanced fork in motocross, the SFF-Air fork is delivered straight from the factory race bikes. It consists of 3 air chambers that riders can easily adjust by using a hand-held air pump to quickly optimise the bike to the conditions, just like setting your tyre pressures. The three-chamber fork uses an Inner Air Chamber that handles the main suspension reaction force (spring-rate), a smaller Balance Air Chamber opposing the main reaction force, and an Outer Air Chamber that supports the main reaction force.

  • Set-Up Made Easy

    For race-winning performance, a motocross engine needs to be durable, efficient and powerful. To win championships, that engine needs to come with the experience and know-how that you only get from Suzuki. The 449cm3, 4-stroke liquid-cooled, DOHC, 4-valve fuel-injected engine packs the perfect combination of broad torque and arm-stretching horsepower perfect for today’s racer. 

  • Factory-Inspired Piston
    Factory-Inspired Piston

    A motocross bike's single piston must endure an explosive environment and needs to perform with efficiency and durability. Through feedback from factory racing, the piston and piston pin were developed using Finite Element Method (FEM) analysis. The RM-Z450 piston pin has Diamond-Like Carbon (DLC) surface treatment, for less friction and increased durability.

  • The Best Chassis in Motocross
