After twenty years of production, the Beta RR models have been transformed into a new breed of enduro bikes. Introducing the all new range of 2-Stroke and 4-Stroke models known as RR X-Pro! Not to be confused with the older brother Race Edition models, the X-Pro models offer the enduro rider with a large range of features and benefits suited for trail riding of all disciplines.

Solely designed to take on the toughest trails with features not found on most other enduro models including a new frame with a 20mm lower seat height, an all-new single spring front fork, elastomeric handlebar mounts, coolant overflow reservoir, as well as a rescue strap on the front fender. Topping off the list of changes is all new plastic that will set the bike apart from the others. 

The 2025 4-Stroke RR X-Pro models range from 350cc - 480cc each with their own characteristics.  

350:  This model is the easiest to handle bike in the range and favors high rev riding but retains a very linear power output
390:  Has ideal handling to power ratio and supreme traction
430:  A high performance engine that is at its best when the rider exploits the long gearing and significant torque
480:  Similar to the 430 but with even more torque and power suited for more expert riders

Features: New durable frame, single sided spring and fully adjustable front fork, lower seat height, larger rear master cylinder, XTrig FlexFix handlebar mounts, traction control, MAP switch to adjust power delivery, electronic key for safety and security, coolant recovery tank, front rescue strap, off-road light and meter package, electric starter, light pull diaphragm clutch with three settings, and easy access air filter box.
