Suzuki RMZ250R M1 – TAKE FULL CONTROL

Suzuki RMZ250R M1: The 250 class in motocross doesn’t forgive the slightest weakness. That’s why we completely redesigned the RM-Z250 to achieve a higher level of performance in “Acceleration, Turning, and Braking” necessary to win in this ultra-competitive arena.

Intensive work by our engineers has once again made the RM-Z250 the leader out of the gate, with the engine featuring increased power across the board and class-leading electronics including WiFi tuning capability, a lighter frame and swingarm plus updated KYB suspension for even better handling, modern styling design, and a laundry list of other updates to make it the most potent motocross bike in its class.

MX TUNER 2.0

Standard with every new MY20 & MY21 RM-Z250 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 settings for easy tuning for different riding styles and track conditions. 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.

PREMIUM KYB SUSPENSION

The 49mm KYB coil spring fork replaces the previous model’s PSF2 air fork. Featuring a unique design that provides a progressive damping setup offering excellent compliance over small bumps while firming up deeper into the stroke to handle bigger hits such as harsh jump landings. Upper and lower triple clamp design has been optimised for rigidity while cutting 60 grams.

Out back, the rear suspension linkage ratio has been changed to firm up short stroke movement while optimising longer suspension action for better traction, and is 14.9 grams lighter than previous. The fully adjustable KYB rear shock has an improved range of adjustment with both high and low speed compression and rebound damping. The rear spring is constructed using thinner but stronger wire (feedback from MotoGP technology) and is 370 grams lighter than before.

MORE POWERFUL ENGINE

Cylinder Head Design

Centre-port cylinder head design contributes to increased output and throttle response by approximately 5%.

Dual-Fuel Injectors

The fuel injection system now features two injectors. Instead of using a single injector that can compromise low-end fuelling in order to supply enough fuel for top-end power, the primary injector delivers precise low-rpm fuelling while a secondary injector at higher rpm provides the extra fuel needed.

Increased Fuel Pressure

Increased by 17% over the previous model and promotes the effective mixing of air and fuel, resulting in improved throttle response.

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).

Suzuki’s RM-Z250 goes another step further with the fourth-generation system featuring updated ECU software. The RM-Z250’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.

ERGONOMICS

Renthal Fatbar Handlebars

Fitted as standard equipment , the top-shelf Renthal aluminium Fatbar offers more strength and less vibration than standard size aluminium handlebars.

FRONT BRAKES

270mm Solid Wave Rotor

The front brake disc diameter has been increased from 250mm on the previous generation to 270mm and the brake pad material has been optimised for more linear response characteristics as you brake harder.

ELECTRONICS

Rich & Lean Couplers

Riders can adjust the engine performance to suit varied track conditions, by plugging in either of two additional fuel-setting couplers to make the most of any riding conditions. Riders can also overwrite these plugs with new maps using the MX Tuner 2.0.
