385.6cc Four-Stroke Engine

Powered by a 385.6cc Four-Stroke Single Cylinder Engine. The reworked airbox from the MY24 refresh carries over to the new X-Pro Model, allowing better airflow to the engine, offering greater performance at medium to high engine speeds, while maintaining the torque at low speeds. This innovation now allows for ‘full-blooded’ power delivery along the entire curve.

Motocross Adapted Frame

A new frame adapted from the RR Racing and RX models has been designed for the new RR X-Pro line up. The new frame features a larger backbone section for less flex and greater durability. The frame redesign also brings a 20mm lower seat height to the RR X-Pro at 930mm.

All New Plastics Kit

The new plastics kit on the RR X-Pro range gives the rider more control of the bike by intruding less into the riders space when completing more difficult manoeuvres, and the new white panels sets the look of the bike apart from the rest.

Redesigned Suspension

An all new front suspension setup has been developed for the RR X-Pro lineup, with a ZF SHC (Separate Hydraulic Chamber) front fork system designed with customisation and adjustability in mind. The front forks are fully adjustable for preload, compression, and rebound damping, while still seeing a weight saving of over 250g.

The ZF Rear Shock has also been redesigned and matached to the new front fork setup. Providing a better overall balance and improved rideability. The progressive linkage improves overall handling.

Traction for All Weather Action

Wet or dry engine maps, and traction control settings can be changed on the fly, and the switch has ben moved to a more convenient location on the handlebar pad.

Through improved mapping, the traction control is now more precise in its operation, mitigating unwanted or overly invasive intervention.

Beta Brakes

Stopping power is provided by a 260mm Wave disc on the front, coupled to a double-piston caliper, and a 240mm Wave disc on the rear, coupled to a single-piston caliper. A new Nissin rear brake master cylinder has been added to provide improved rear brake performance. The new reservoir holds a larger volume of fluid, helping to cool the braking system down under extreme scenarios.

XTrig FlexFix Bar Mounts

New XTrig FlexFix Bar Mounts are standard on the RR X-Pro lineup. The new mounts are designed to reduce vibrations and provide greater rider comfort and grip, reducing rider fatigue.

Front Tugger Strap

The RR X-Pro lineup now features a front tugger strap as standard, to help riders lift the front end out of difficult sections or to aid in recovery

Cooldowns

Newly added to the RR X-Pro lineup is a coolant overflow reservoir, which helps to reduce the loss of coolant in extreme riding conditions.
