Overview:
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 RR Race 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.
