OVERVIEW

Serving as the flagship of the 2-stroke line, the 2027 RR Race 300 combines massive torque with cutting edge chassis dynamics for the ultimate edge in extreme enduro and cross-country competition. For 2027, Beta’s engineers heavily updated the 300 power plant by adjusting the engine head geometry and exhaust valve timing. This results in a more progressive response at low and medium revs, delivering highly controllable power and greater usability of torque without losing its aggressive racing character. Designed as a pure premix racer to minimize weight, the 300 also benefits from updated KYB suspension settings, reinforced chain guidance, and a redesigned front mask housing a powerful new LED headlight. It is the ultimate expression of Beta’s Rideability, ensuring the bike’s immense power is always highly tractable.
