Beta, the boutique Italian motorcycle manufacturer known for its enduro, dual-sport, and observed trials motorcycles, is making a move into the American motocross market with the US-only 2021 Beta 300 RX. One might expect this is just a slightly modified Beta enduro bike, but there is more to the new RX than that.
- A 293cc two-stroke motor powers the 2021 Beta 300 RX. Rather than going up against the established 250 two-strokes, Beta is staking out unique territory with an open-class motocrosser. According to Beta, the motor in the 300 RX “has been tuned exclusively for moto in every way.” Like the enduro version of the engine used in the Beta 300 RR, the RX has V-Force reeds, an adjustable power valve, two power modes, a six-speed transmission with a Brembo hydraulic clutch, and electric starting.
