RM-Z450

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 MY23 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.
