Call for Price
Overview

The RR Race 300 is the top of the 2T range: power, torque and smoothness combined in a bike capable of tackling any obstacle. A model designed for the most experienced riders who are looking for absolute performance without sacrificing control.

The RR Race 300 2-stroke engine has been completely redesigned to enhance torque and progression at all revs. New crankshaft, updated crankcase with larger bearings and a redesigned cylinder with new ports. The cylinder head, now with a redesigned combustion chamber, works in conjunction with the dual spark plug system for more efficient combustion and optimal power management in all conditions. The result is a full-bodied engine that is manageable at low revs and robust at high revs, capable of combining torque and power with unparalleled harmony.

The RR RACE 300 is the ideal bike for those looking for a 2-stroke with benchmark performance, delivered in the simplest and most intuitive way possible, allowing every rider to get the most out of every cc of the engine. The engine’s usability will allow anyone to always get the best out of themselves.

ayaba AOS closed cartridge fork, ø 48 mm has anodised internal parts and specific treatments that minimise friction. Compression and rebound adjustments allow you to always find the ideal setting.

An aggressive and unmistakable look: the dedicated livery enhances the Race character with bold lines and exclusive colours, recalling the factory soul of Beta and making you stand out on the track.

The map switch button located on the handlebar allows you to select two engine maps: Full Power, which offers all the power and responsiveness of the engine, and Soft, which softens the power delivery, making it more manageable on slippery surfaces or when greater traction is needed.

The double spark plugs improve carburetion, torque and power, reducing fuel waste. The system also ensures continuous operation even if one spark plug burns out.
