RM-Z450

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.

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.
