The Beta RR Enduro project continues to grow and improve, boosted by successes on the racetracks and by the great commitment of the technical and R&D departments in Rignano sull’Arno. The RR Enduro 2015 models are lighter and more agile, and their great power and torque are more easily controlled. They are the ideal bikes for enthusiasts and the winning solution for victory-hungry racers.

The RR Enduro 2T 2015 range has also evolved, the 250 version featuring certain technical innovations and the 300 version featuring special parts from the Racing MY14 model. The objective here is to increase the smoothness and regularity of power delivery, seeking and obtaining an even more direct and progressive response of the engine to the throttle, making engine power fully available.

2015 Beta RR 2T 300 Features and Benefits:

The RR 2T MY 2015 engines have undergone some changes aimed at ever-better control of engine management, without reducing performance in terms of lightness and power typical of 2T engines with high specific power.

the engine takes over the complete package comprising the cylinder, combustion chamber and CDI coming from the 300 2T MY 2014 Racing version. In particular, the reduced width of the exhaust outlet and better exhaust outlet-flap coupling enable this engine to guarantee an increasingly immediate and precise response to the throttle, and an excellent linearity of power delivery without interfering in any way with the maximum power and torque figures. The combustion-chamber profile, together with the digital electronic control unit, make it possible to optimise engine output in every stage of operation seeking as the primary objective to make the increase in performance, due to opening of the exhaust flap, as gentle and progressive as possible.

A new silencer, for this version with an internal pipe of a smaller diameter compared with the 300 version, improves the precision of response to the throttle and increases peak revs.


The Sachs USD ? 48 fork developed in close collaboration between Beta and Sachs features numerous important innovations: a new design of the extension piston with “three slot” geometry in order to improve the oil flow and make it more direct so as to absorb violent shocks more progressively. To improve the general smoothness of the fork, particularly on the initial breakaway friction, a spring-support release system has been included to eliminate rotational friction, the design of the sleeves and sheaths has been modified increasing the distance between the slider DUs, also reducing their height. Finally, the spring profile has been redesigned to guarantee better insertion inside the sleeve. All the connections have also been adjusted, increasing precision.

Shock absorber

A new internal piston with oil passages that have been redesigned to improve its flow and reduce overheating during operation. This means that the shock absorber offers more stable performance, precise and reliable even under very intense use.

Handlebar pads

Ideal for the most extreme off-road riding and compliant with the standards required by FIM regulations.


The padding has been redesigned with softer foam.


The renewed look streamlines and adds character, maintaining the classical Beta colours.

“Since 1904 the Beta engineers have strived to provide innovative products that inspire, excite, and perform. 2015 is no different in that they continue to provide their customers with new models that continue to advance in both quality and features.” ----- Total Motorcycle

“The buzz from these bikes has really set the Enduro and Hare and Hound paddocks talking which compliments the talking that the bikes are doing for themselves! The new 300 RR is reportedly the best two stroke engine made to date with a new design power valve system that was fitted to the 300 "2014 Factory Model" produces some of the best Torque, smooth delivery and top power of any previous 2t Enduro Bike! Quite a statement but the proof is in the pudding and will be confirmed when the various testers from the worlds press goes to print over the coming months ahead.” ----- Edmondson-Racing
