Introducing the MY26 Beta RX 250 2T
Adding a lightweight, high-revving option for riders. With a completely new engine architecture, it offers explosive performance, nimble handling, and the ability to challenge in competitive race environments.
Head: The 250cc provides riders with a high-revving engine that competes with the likes of 250 4T bikes.
Cylinder, piston and power valve: Betamotor engineers developed new cylinders and pistons, designed specifically for the RX 250 2T engine. The power valve was calibrated differently between the models by adopting different springs.
Crankshaft: The RX 250 2T has a stroke reaching 72mm.Crankcase: new engine crankcases, with different internals Graphics: a modern race look, simple yet bold, the final touch to the Italian RX range.
Radiators: structurally strengthened to prevent deformation, even during heavy use.
Shared Features Across the RX Range
All 2026 RX models share the following upgraded features, ensuring consistency in quality and performance: The frame now features a cast-in brace to further strengthen the frame around the steering neck area, increasing stiffness.
Aluminum subframe offering light, yet stiff structure with the rigidity to overcome the demands of motocross. Access to the air filter remains unchanged and is tool free .Kayaba 48mm forks and 50mm shock, calibrated specifically for MX applications.
Nissin brakes with Galfer discs (260mm front / 240mm rear) for powerful, modular braking.
Xtrig Flexfit handlebar mounts for enhanced comfort and vibration dampening.
Electric start with lithium battery, lighter and a must for quick starts.
Non O-ring chain, lighter and smoother.
Two engine maps (wet/dry) on all 2T models
