2023 Suzuki RM-Z450

The RM-Z450 wraps a sleek, race-ready appearance around a strong 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 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.

Suzuki Protection Plan is a comprehensive plan that covers all mechanical, electrical and computer systems on your Suzuki Motorcycle or ATV. Ask your local Authorized Dealer about Suzuki Protection Plan for extra peace of mind.

Motocross is a relentless game, and the technology and training needed for bike and rider to excel are too. Suzuki poured more than 40 years of open-class racebike engineering into the RM-Z450 to make it the hardest-hitting, sharpest-handling, best-balanced and most rider-friendly production motocrosser in company history.

Features may include:

• Great throttle response delivers high peak power.

• Evolved traction management system helps the bike hook up.

• Suzuki Holeshot Assist Control (S-HAC) gets you out front.

• Frame and swingarm balance lightness with strength.

• Chassis dimensions blend nimble handling with stability.

• Coil spring fork provides great performance and easy tuning.

• Showa BFRC (Balance Free Rear Cushion) shock settings delivers remarkable and controlled damping response.

• Bridgestone X30 tires bring outstanding grip.

• Large 270mm front brake rotor increases stopping power and feel.

• Compact rear master cylinder is designed to prevent mud from collecting on it and from catching on the rider’s boots.

• Aggressive styling blends function with Suzuki character.

• Narrow cockpit lets rider move with ease for maximum racing performance.

• Fuel couplers are included for quick and easy EFI Tuning.

• The 449cc, liquid-cooled, four-stroke, four-valve, DOHC engine is the latest incarnation of Suzuki’s proven and reliable fuel-injected powerplant.

• The engine has high peak horsepower with strong torque at lower engine speeds for excellent throttle response through the entire rev range.

• The cylinder head intake port shape creates a high amount of tumble flow to the incoming fuel/air to increase power output.

• The air cleaner’s large and straight opening creates a more direct air path to the throttle body to increase performance.

• Suzuki’s advanced fuel-injection system creates extra-smooth power delivery, high fuel efficiency, and superb reliability.

• The RM-Z450’s throttle body design locates the fuel injector, fed by a high-pressure fuel pump, so it sprays fuel directly at the butterfly valve to improve atomization of the fuel/air charge.

• This throttle body design eliminates complex control linkage, so the rider feels a more direct connection to the engine.

• The intake camshaft profile has more valve lift than the prior generation RM-Z450, increasing power at all engine speeds.
