RM-Z450

• 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. Specialised 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 traction management system features Suzuki Holeshot Assist Control (S-HAC) with three mode settings, which helps maximise acceleration to put the RM-Z450 out front through the three critical stages of a motocross start.
• The engine features great throttle response and high peak power.
• Responsive SHOWA coil-spring front forks feature strength, durability, and ease of daily maintenance, easy tuning, and a light, optimised upper triple-clamp.
• Showa Balance Free Rear Cushion (BFRC) shock better controls the stroke and smooth out reactions to bumps and chop, even under severe braking.
• Lightweight wheel rims feature a structural design that maintains strength while reducing unsprung weight, and an anodised black finish for tough looks.
• Bridgestone BATTLECROSS X30 tires bring outstanding grip that helps maximise motocross track performance.
• The frame and swingarm balance lightness with strength, and chassis dimensions blend nimble handling with stability.

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 tuning of the electronic fuel injection system.

ADVANCED ELECTRONICS

The RM-Z450 has an improved system that helps improve traction. It constantly checks how much the rider is opening the throttle, the engine speed, and what gear is engaged. Based on this information, it adjusts the ignition timing and fuel injection to give the best grip on different riding surfaces.

Unlike street bikes, which often track rear wheel spin, this system doesn’t monitor that. Instead, it’s designed specifically for motocross, making small adjustments all the time to keep the bike’s traction just right for off-road riding.

The bike also comes with Suzuki Holeshot Assist Control (S-HAC), a feature that helps riders get a strong start from the gate. It offers three different launch modes, so riders can pick the one that best suits their skill and the starting conditions. Each mode has three stages, helping riders control their throttle during the initial launch and as they accelerate to full speed.

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