2026 Beta 350 RR X-PRO 4-Stroke

“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 2025 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.

As always, the range is made up of 8 different models, each with its own personality, to cater to the needs of a very diverse spectrum of riders. There's the perfect X-PRO for every rider.  Beta USA suggests riders who would like to discover the different models to reach out to their local Beta dealer to see when they will be holding their Beta “POD” demo day so the different models can be ridden back-to-back.

The 4-stroke engines received new maps to improve their delivery along the entire range. Whatever the displacement, Beta engineers improved their linearity and usability, to better manage the power available, at any speed.

Features May Include:

Swingarm

• The rear wheel axle diameter has been increased 2mm, for a total of 22mm. This new component guarantees greater stiffness and torsional resistance, resulting in better performance when the rear wheel is flexing or in heavy turns.

Coolant Recovery Tank:

• 200cc Coolant expansion tank prevents overheating by recover-ing lost coolant into the recovery tank, which will then refill radiators as the engine cools.

Battery:

• 4T models will have a new, lighter, more-performing battery, for safer starts under any usage conditions.

New Frame

• Adopted from the RR Race Editions and RX Models, the new frame provides a larger backbone that is stronger with improved control through less flex

All New ZF SHC Front Fork

• Lighter weight, single-sided spring, fully adjustable preload, compression and rebound dampening.
• Provides riders with a more planted feel

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

Low Seat Height

• Three quarters of an inch lower than the 2024 RR models.
• Better seat shape with softer foam for a more comfortable ride

Handlebar Mounts

• XTrig FlexFix isoelastic bar mounts reduce rider fatigue and vibration. Also allows for flexibility in handlebar adjustment
