OVERVIEW

divider

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.

POWER DELIVERY

UPDATED 300 ENGINE

Beta's engineers have refined the 300 2-stroke engines by adjusting the engine head geometry and the exhaust valve timing, with the aim of making the response at low and medium revs even more progressive. The result is more controllable power delivery during throttle control, without compromising the performance and racing character that have always distinguished this model. This leads to greater usability of torque across the entire rev range.
