2017 Beta 300 RR 2-Stroke

300 RR 2-Stroke


  • SACHS FRONT FORK: RR models arrive with the Gen4 Sachs front fork. This fork has been tested by the Beta engineering team many times over to improve the feel of the front end. We feel this is the best open cartridge fork on the market today.
  • OIL INJECTION: Electronic oil injection eliminates the mess of pre-mixing your fuel. System electronically regulates the oil flow depending on throttle position. This system reduces smoke by more than 50%.
  • ADJUSTABLE POWER VALVE: All Beta 2 strokes have an adjustable power valve that uses a 5mm allen socket. Riders can simply dial it in for less hit or back it out for more allowing the engine to be adjusted per the rider’s preference.
  • FMF EXHAUST: All Beta RR 2 strokes come standard with a nickel plated FMF exhaust pipe and an exclusive FMF muffler designed by the Beta engineers. This is an option on most other brands.
  • PUSHBUTTON SEAT: All Beta RR and RS models arrive with a push button quick release seat. This allows for easier access to the air filter, battery, and tool kit.
