The main update to the 2015 MY Beta 350RR is the introduction of Electronic Fuel Injection (EFI), which ensures optimum fuel/air mixture at any altitude and temperature. As a result, the 350RR has a more linear, predictable engine response, no matter the riding style or the conditions one might encounter on the dirt track or trail.
The proven Sachs USD 48 mm fork and Sachs rear shock have been improved with new pistons, making for an overall more easy-to-handle bike. On the tech/engine side, it sports a four-stroke, liquid-cooled, 349cc engine mated to a six-speed manual transmission.
