Product Description

The Art of Rideability in the MX World

RX 300 2T is a bike that launched as an exclusive motocross bike for the US market in 2021, as well as in Australia in limited numbers but is completely new for the European market. The success of this project, aided by the ever-growing experience accumulated in the race field inthe MXGP World Championship with the 450 4T, have led the Tuscan brand to open the throttleon the evolution of the bike which today is configured as a fully-fledged motocross bike.

This limited production model will be produced for the first time outside the US & Australia, making the RX 300 2T a unique opportunity to add this bike to your garage, a model which for Beta marks the return to the motocross market and which will open the way for a new range oftotally new models arriving soon.

The RX 300 2T is a unique bike in its class, the perfect combination of power and control, andborn with a racing spirit due to it being dedicated to the race track. It still features the ease ofuse typical of the Betamotor family, however, fully focused on fun without compromises.

The all-new RX 300 was designed for the moto-minded rider looking for the style andperformance that can only come from Beta of Italy. The “factory bike sound” coming from themuffler sets this model apart from the rest of the brands on the track. Many of the Betaengineers come from a motocross background which allows them to exercise their talents.

The MY24 Beta RX 300 has been specifically developed for motocross riders through its extensive list of features that include:

  • Engine: the RX 300 offers a high level of performance, especially in the mid-rangeand top end of the power delivery, yet still providing excellent torque, thus offering anenjoyable and progressive ride which is always under control, focusing on the concept ofrideability in all situations.

  • Crankshaft: this component has been lightened with a reduced diameter married to the engine main cases, exclusive to the RX to provide faster acceleration at higher engine speeds.

  • Exhaust valve: an adjustable valve giving you the ability to change the power delivery to suityour needs, providing excellent tunability for riders of all abilities.

  • Carburetor: Keihin PWK38

  • Fork and shock: are Kayaba (KYB). This suspension package isexclusive to the RX model. Beta engineers worked closely withKayaba to develop the perfect settings based on the overall RXmodel’s geometry.
