• Narrow cockpit lets rider move with ease for maximum racing performance.
• Fuel couplers are included for quick and easy EFI Tuning.

Traction Control

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.

Fuel Injection

Designed for motocross use, the lightweight, battery-less, electronic fuel injection system is key to the engine’s efficient power delivery.

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.

Mode A:
For hard surfaces or slippery conditions at the starting gate. In this mode, S-HAC alters ignition timing at the moment of launch and the ride over the gate to reduce wheel slip to deliver a smooth takeoff. It also advances ignition timing during this sequence for stronger acceleration. After six seconds or when you reach fourth gear, the system shuts off and returns to normal ignition timing.

Benefit of Mode A: For novice riders, and/or hard and slippery traction conditions, use Mode A for a more controlled launch.

Mode B:
When conditions at the starting gate have better traction, and a more aggressive launch is desired. S-HAC will advance the ignition timing to allow increased throttle response and stronger acceleration off the line. The ignition timing alternation is in a similar sequence as Mode A, but with increased overall timing advance. The system will return the ignition to normal operation in three situations (whichever happens first): After six seconds, when you reach fourth gear, or when the throttle is closed. The system then shuts off and returns to normal ignition timing.

Benefit of Mode B: For skilled riders, and/or good starting conditions, use Mode B for a more aggressive launch.

Base Mode:
Standard power launch, no action required on the S-HAC switch.

• Hexagonal aluminum rails are used on the sub-frame for lightweight, a slimmer appearance, and easier air filter service.
• The sub-frame rails route inward to slim the bodywork, but also route upwards to provide additional space for the large air cleaner and the advanced BFRC shock absorber.
• Like the trim sub-frame, all of the bodywork is slim to enable the RM-Z450 rider to move freely in the cockpit, especially during spirited riding.
• The strong Renthal aluminum tapered handlebar has a straighter bend than prior models to help aid the rider during aggressive maneuvering.
• The light upper fork bracket was developed to complement the Showa coil spring front suspension and handlebars.
• For effective stopping performance and feel, a large 270mm, wave-style front brake rotor with a twin piston caliper are used.
• The trim rear brake master cylinder hugs the frame beam to reduce dirt contamination and the chance of the rider’s boot touching it during riding.
• Suzuki beak-inspired styling has a sharper front fender and radiator shrouds blending into side covers and an upswept tail, to promote the impression of speed while reducing weight and easing service.
• The functional styling and the motorcycle’s trim chassis permit a variety of rider positions that facilitate control and comfort.
• The seat base, inner fenders, and side covers were developed to reduce the amount of moisture and dirt that gets to the air cleaner. This helps prevent debris from contaminating the air filter element.
