2026 Altis Beta

<h3>2026 Beta 350 RX</h3><p>Beta has added two new motocross models to join the big brother 450 in the RX range. All-new 250 and 350 RX 2 strokes are the new bosses in town! Beta&#8217;s 450 RX has been racing on the world MXGP tour for four years and the AMA USA Supercross series for two and has proven to be a serious contender. The Italian Beta engineers decided to &#8220;Go Big&#8221; for 2026 and add not only a 250 cc bike to race in the proper classes but also added a 350 RX model as well for everyone else! All Beta MX models are designed with the trademark RideAbility in mind. A motorcycle that is overall easier to ride.</p><p>350 RX: All new for 2026, this new model replaces the 300 version for the 2026 season. New engine cases, bore and stroke, as well as a twin-plug head to ignite the special power only a big-bore 2-stroke can provide. The longer crankshaft, combined with the final gearing ratio of 14/47, provides a large amount of torque and overall horsepower that will turn some heads. This new 350 motocrosser will thrive in many different track conditions. Clearly in a class of its own!</p><p><strong>Features may include:</strong></p><ul><li>Kayaba (KYB) Suspension</li></ul><p>Fork (48mm) and single shock (50mm) are specifically calibrated on the new range models, focusing on their rideability and stability when the pace rises.
