THE WINNING BALANCE.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. |
FASTER. HIGHER. HARDER.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. |

Traction ControlThe 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.

HOLESHOT ASSIST CONTROL The Suzuki Holeshot Assist Control (S-HAC) is a selectable launch system derived from the factory race bike to help the rider’s takeoff from the starting gate for an early lead. There are three launch modes riders can choose for the best option per their skill level and starting conditions. There are also three stages to Mode A and Mode B of the S-HAC system. This helps riders at the moment of launch, when crossing the gate, and through acceleration to the full speed. The S-HAC settings for Mode A on the RM-Z450 are specially tuned to aid the rider’s throttle control during launches. |
ModesMode 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.
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.
Base Mode: Standard power launch, no action required on the S-HAC switch. |
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. |
