Nothing Corners Like A Suzuki

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 latest generation RM-Z450. 

The RM-Z450 already has a heritage of 29 world and national championships to build on, including five AMA 450 Motocross, two AMA 450 Supercross,  three Australian Supercross   and three Australian Motocross Championships.  With this winning history comes a well-balanced engine, chassis and electronics package, plus dramatic styling.

The result?

The most potent, best-balanced and competitive RM-Z450 produced yet.

MX Tuner 2.0

Standard with every new MY24 RM-Z purchased, the plug and play MX Tuner 2.0 allows users to alter the engine mapping via the intuitive smartphone WiGET app, available on iOS and Android devices.

The WiGET app comes with several pre-installed factory-developed maps for easy tuning for different riding styles and track conditions.

In just a few minutes the power delivery can be altered for softer delivery settings for hard packed surfaces or dial-in maximum power for deep, loamy conditions and amazing drive out of the corners.

For the more experienced tuner, the possibilities are practically endless with the ability to create fully customised maps with specific settings for 36 points of ignition timing and 36 points of fuel injection delivery.

  • Power Everywhere

    The latest generation RM-Z450 engine has more low-end torque, a flatter overall torque curve, faster and yet more controllable throttle response, and more peak power than the previous version.

  • Refined Cylinder Head

    Cylinder head port shape was optimsied and the strength of the tumble flow increased by 25%. Improvements to reduce surface roughness within the ports make them smoother, and this contributes to greater engine output.

  • Mikuni Throttle Body With Undermount Injector

    The fuel-injector spray path aims fuel upward to hit the throttle butterfly valve directly for improved atomisation.

  • Optimised Intake Camshaft

    Features increased lift, improving intake efficiency and increasing power output at all engine speeds.

49mm SHOWA Spring Fork & BFRC Shock

The RM-Z450 is equipped with the latest SHOWA front and rear suspension components, delivering improved responsiveness and traction, enhanced ability to absorb impacts, better chassis stability, overall feedback to the rider, terrain feel and improved comfort.

Up front, an updated 49mm Showa coil-spring fork based on works A-type design replaces the previous air fork design.  Performance has been increased significantly and offers a more consistent feeling throughout a moto. Bike set-up and daily maintenance is also much easier for a wider range of riders. 

The Balance Free Rear Cushion (BFRC) rear shock design shares technology with Suzuki’s flagship GSX-R1000R sportsbike. The design balances pressure above and below the piston to better control the stroke and smooth out reactions to bumps and chop, even under severe braking.

Suzuki Holeshot Assist Control (S-HAC)

All the power in the world  won’t do any good if you can’t transfer it to the ground, and Suzuki’s innovative electronics work transparently with the rider for maximum acceleration on any type of dirt or track conditions.  Suzuki’s  third-generation traction management system, with a significantly updated S-HAC (Suzuki Holeshot Assist Control) system and more powerful ECM (engine control module).

The RM-Z450’s S-HAC system monitors throttle position and gear position in order to adjust ignition timing for maximum acceleration through the three critical stages of a motocross start: releasing the clutch, getting drive over the starting gate, and then powering  down the start straight.

Three settings are available:
A-mode: Intended for hardpack surfaces where controlling wheelspin is paramount
B-mode: For normal dirt conditions with good traction
OFF: For normal unassisted take-offs.
