300 RR X-PRO 2-Stroke

Overview:

"Rideability”: a term that Beta USA founded in 2009, originated from the moto journalists while testing Beta’s different models, terms such as “I moved up a class”, and “It feels so planted” were common so the marketing team decided to own the phrase Rideability. The 2026 Beta X-Pro models are the perfect example of this term. Riders of all levels appreciate the feeling that a Beta provides the rider, the overall balance of the frame and engine placement provides something that must be felt only through riding a Beta. It will not take riders long to understand how well balanced the X-Pro models really are. The Beta engineering team, based out of Florence, Italy continued throughout the Winter and Spring to further enhance the range, making small improvements here and there that ultimately improves the feeling even over the prior year.  

With the new frame introduced on the 2026 models, X-PRO handling has been improved even more with the addition of the larger real axle, now 22mm diameter, and a new front brake caliper, both adopted from the 450 RX model. These updates along with new, larger engine main bearings and a new second gear in the transmission on the 250 and 300 models, make for an improved platform overall.

Front Rescue Strap
Designed to aid when needing to lift the front wheel out a difficult situation

Rear Master Brake Cylinder
Larger volume of fluid over previous models to reduce heat during extreme braking

Lower Seat Height
Three quarters of an inch lower than the 2024 RR models. Newly designed seat shape with softer foam for a more comfortable ride.

Handlebar Mounts
