300 RX,Beta USA say the new seat drops “roughly ½” lower than the previous model and that helps turning and feel in the corners. Beta have been testing and taking feedback since launching the RX model last year and found adjusting some weld locations and lengths improved flex, which in turn also helps rider feel.
The new diaphragm spring clutch on the 2022 RX is already fitted as standard to the RR enduro models and boasts lighter lever feel and more progressive control. They say both “engagement and disengagement” have been improved, while the clutch is beefed up to be “capable of transmitting more torque”.
This new clutch also has three different settings so you can personalize the RX’s clutch feel to meet your riding style. It’s a simple process, you rotate the support plate behind the outer clutch cover and that affects how smoothly or firmly the clutch releases depending on the rider feel.
The other detail change is an upgrade to the KYB front fork valving has been updated to provide less bottoming and harshness.
