Renowned Italian off-road brand Beta has made an unexpected move into motocross with the introduction of its 2021 model Beta 300 RX in the United States.

Specifically powered by a 293.1cc two-stroke engine, the new Beta 300 RX has been tuned for motocross, featuring electric start, a six-speed transmission and an adjustable power-valve.

The chassis includes a frame purpose-built for the RX model, as well as a KYB closed cartridge front fork and Sachs rear shock, which have internal settings that were developed by Beta USA’s in-house suspension department.

“We wanted to build an MX bike that utilised many of the characteristics that our off-road race bikes have, but with more power and stiffer suspension,” Beta USA president Tim Pilg commented. “The RX model shows how much fun a two-stroke can be. The sound and feeling of the bike is unmatched and I hope our future owners of the model will appreciate the effort put into the bike – it is truly special.”

Additional features of the RX include a lightweight lithium battery, 19-inch rear wheel, push-button seat removal, Brembo hydraulic clutch, Nissin front and rear brakes with oversize rotors, plated Arrow exhaust pipe, composite rear sub-frame and a V-Force reed assembly.

Interestingly, Beta’s RX 300 promotional edit includes Jake Weimer, the 2010 250SX West champion in Monster Energy Supercross riding alongside Beta USA Factory Team manager Rodney Smith – a five-time Grand National Cross Country (GNCC) champion and current factory Beta rider Chance Fullerton.

Beta has emerged as the dominant force in the Enduro World Championship during recent seasons, capturing the EnduroGP and Enduro 1 titles with Brad Freeman, while Steve Holcombe rode to the Enduro 3 crown in a convincing display from the Italian manufacturer.
