Beta’s second-generation 300 RX two-stroke features a few significant upgrades for 2022.
For starters, the seat height has been reduced one-half inch due to a new seat. The RX has a new diaphragm clutch that Beta claims provides a lighter pull while offering more progressive control. In addition, the new clutch, Beta says, has better engagement and disengagement and is now capable of transmitting more torque. And, you can adjust the clutch settings via three different spring options, by rotating the support plate behind the outer clutch cover. As a result, clutch engagement can be adjusted to release smoothly or more firmly depending on the rider’s needs.
Frame rigidity has been altered for improved rideability, and the KYB closed-cartridge fork has new internal settings. Beta says the 2022 300 RX will be available January 2022 but in limited numbers. MSRP is $9199.
