FEATURES
SUZUKI HOLESHOT ASSIST CONTROL

MAXIMUM POWER WHEN IT COUNTS

Win the holeshot with 3 modes, including off, that match the engine’s power delivery to diverse starting conditions for maximum control.

A-MODE B-MODE
Perfect for smooth and controlled launches on less than ideal surfaces Increased throttle response and stronger acceleration
In A-Mode, the ignition timing is altered to prevent wheel slip. After 1.2 seconds, or when you reach third gear, the system shuts off and returns to normal ignition timing. In A-Mode the indicator light flashes slowly.

B-Mode advances the Ignition timing for more power off the line. The ignition returns to normal operation when:
    1. Throttle has been open for 4.5 seconds
    2. Shifting into 4th gear
    3. The throttle is closed

In B-Mode the indicator light flashes quickly.

SHOWA SFF-AIR FORK

BIG AIR UP FRONT

The SFF-AIR is 2.5 pounds lighter than spring forks with three micro-adjustable air chambers.

Riders can adjust the air pressure trackside with a simple hand pump using each chamber’s separate and easily accessible air valve. Complicated, expensive spring changes are history.

Inner Air Chamber Balance Air Chamber
Main suspension reaction force. Opposes the main reaction force.
Outer Air Chamber Quicker Damper Response
Supports the main reaction force. Adjust the damper in 13-ways, and compression in 8-ways. Damper size is increased, which results in quicker damper response.
REDESIGNED ENGINE

PRIMED FOR VICTORY

The 2015 RM-Z450 delivers easier starting, a more consistent launch off the line, and a smoother spread of torque and horsepower for podium finishes all season long.

• Fuel-injected 450cc four-stroke

• Easier starting hot or cold

• 30mm longer Kick lever

• Less rider fatigue

REDESIGNED FRAME

OPTIMIZED RIGIDITY

This time around the RM-Z450’s frame is lighter with increased handling in the corners and a plusher ride from start to finish.

• 4% reduction in weight

• Redesigned down tube

• Reshaped mainframe inner ribs

EFI COUPLER SYSTEM

CONSISTENT PERFORMANCE

Suzuki was the first to develop fuel-injection on the worldwide motocross circuit, and the 2015 RM-Z450 continues this legacy of innovation with its EFI Coupler System. Make the most of any track conditions by running richer or leaner with the choice of two fuel-setting couplers for precise throttle response.
