Info Photos Specifications

Suzuki's flagship motocross machine is the 2027 Suzuki RM-Z450. Its foundation is the bike that captured the 2026 AMA Supercross Championship. The 2027 version adds new KYB suspension, RK Excel rims and an exhaust silencer that complies with AMA and FIM sound regulations, resulting in a ride that feels more compliant and handles precisely on the track.

• Proven 449cc engine: this fuel-injected, liquid-cooled single uses a four-stroke, four-valve DOHC design and produces high peak horsepower along with strong torque. The outlet tube on the air cleaner has been reshaped to improve intake efficiency.
• New KYB suspension: up front sits a coil-spring fork with adjustable damping and large-diameter inner tubes, and out back a fully adjustable shock with a linkage-type design, for plush absorption of bumps and for traction.
• Twin-spar aluminum chassis: the frame and the beam-style swingarm strike a balance between strength and lightness. Handling gets help from a new upper fork bracket.
• RK Excel rims and Bridgestone Battlecross X30 tires: each was developed at the racetrack, and each is strong and lightweight.
• MX-Tuner 4.0: using an app on your smartphone, you can adjust ignition and fuel injection settings.
• S-HAC and traction management: Suzuki Holeshot Assist Control along with traction management assist with drive and starts.
• Five-speed transmission: shifts precisely and is paired with a wet multi-plate clutch featuring a cam-release mechanism.
• Renthal tapered aluminum handlebar: thanks to its straighter bend, the bike is easier to maneuver.
