2024 Suzuki RM-Z450 Dirt Bike 5-Speed 449cc single cylinder

• Strong, Usable Engine Performance* 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.
• Unmatched Cornering Performance* 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 deliver a remarkable and controlled damping response.* Bridgestone X30 tyres bring outstanding grip.
• Controlled Braking Performance* 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.
• Functional Styling* Aggressive styling blends function with the Suzuki character.* Narrow cockpit lets rider move with ease for maximum racing performance.
• Rider-friendly Tuning* Suzuki’s MX-Tuner 2.0 is supplied, providing quick fuel injection and ignition tuning through an easy-to-use smartphone application.* 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.

• Included with the 2024 RM-Z450 is Suzuki’s MX-Tuner 2.0 that provides the ability to easily adjust the fuel injection and ignition system settings for optional race performance.* Using a smartphone application that wirelessly connects to the MX-Tuner’s compact transceiver, fuel delivery and ignition timing can be quickly changed.* The MX-Tuner application can pre-program personalized settings into the ECM that can be activated by plugging in one of the supplied fuel couplers.* Racers and tuners can easily change settings to match performance-related updates.* The application can save a number of settings for different tracks or weather conditions, plus settings can be exchanged with other racers.* Real-time engine data and run-time information are accessible to help you stay on top of bike maintenance.
• Suzuki’s proven, easy-to-use fuel couplers are also included to simplify EFI tuning.* For quick fuel adjustments to suit riding conditions, two couplers are provided. One is for a richer-than-stock and another for a leaner-than-stock fuel setting.* Riders can change fuel settings in seconds by simply connecting either coupler to the wire harness.
• The RM-Z450 features an evolved and efficient traction management system. The Electronic Control Module (ECM) continually measures throttle opening, engine speed, and gear position and then adjusts the ignition timing and fuel injector duration to fine-tune the engine output to deliver the best traction for the riding conditions.* The RM-Z450’s traction management system is different from a street bike traction control system, as it does not measure rear tire spin. Because the needs of a motocrosser are different than a street bike, this system offers constant adjustment that maximizes traction at all times.

• The well-sorted, five-speed transmission enables precise gear shift operation. This precise transmission feel is the result of an accurately machined shift cam for exact gear selection. Specialized machining processes also increase the precision of the matching gears.
• The multi-plate, wet-clutch uses a rack-and-pinion clutch release mechanism for precise feel of the engagement and disengagement points while riding.
• The lightweight chain guide is shaped to accurately route the drive chain smoothly.

• The RM-Z450’s twin-spar frame and twin-beam swingarm design continues Suzuki’s tradition of delivering the best-handling motocross machines available.
• This aluminum alloy, twin-spar frame combines cast and extruded sections to achieve superior front-and-rear weight distribution while balancing strength and weight.

• Competition motorcycles like the RM-Z450 can only be ridden on non-public land in California per California Air Resource Board (CARB) regulations.
