2026 Beta RX 350

The bike for those seeking the thrills of a high-displacement 2-stroke, but with always manageable power delivery. The engine of the RX 350 2T is designed to deliver substantial and constant thrust from low revs; power delivery is progressive, making the bike easy to ride and suitable for a wide range of riders.

The RX 350 2T engine has been designed to offer you the best of both worlds, combining the advantages of a 2-stroke with power delivery similar to that of a 4-stroke, full and linear at any rpm. Power delivery has been optimised to be full and linear, with consistent torque from low revs. This allows for smoother and more effective riding, making the most of all that power with less effort.

The RX 350 2-stroke engine was designed with a specific goal in mind: to make the great power of a 2-stroke motocross bike fully exploitable by every rider. Exclusive solutions such as the dual-ignition cylinder head and long-stroke crankshaft work together to create a smooth, linear power delivery. This translates into a more fluid, less tiring and incredibly effective ride, allowing you to focus purely on the perfect line.

An exclusive feature of the 350, the double spark plug head ensures optimal combustion at all speeds. Smoother power delivery and greater combustion, especially at low and medium speeds, for easier and more intuitive riding.

The Nissin system with 260 mm (front) and 240 mm (rear) Galfer discs ensures powerful and modulated braking. It allows you to precisely manage the 250’s great responsiveness, ensuring decisive braking and total control to maintain maximum speed in corners.

The 14/47 final gear ratio was chosen to enhance the linearity of the 350 engine. This longer ratio allows you to make the most of the engine’s torque, reducing the use of the gearbox and ensuring a smoother ride.

The silent blocks on the handlebar reduce vibrations, increasing riding comfort. On a bike like the 350, this translates into less fatigue and a consistent, high-performance pace throughout the race.

The reinforced structure of the radiators ensures maximum reliability and constant cooling, even when the generous torque of the 350 engine is used for long periods. A guarantee of consistent performance from the first lap to the last.
