Model Features:

The smallest bike in the Beta range, the lightest and easiest to handle of them all. In pure racing style, suitable for both young riders coming up from the lower categories and more expert riders looking for a fun bike.

Following intensive across-the-range development and technical refinement, the biggest new features on the RR my 2019models can be summed up as:


  • New engine control unit (ECU): guarantees a more powerful spark at high revs, improving combustion and engine performance.
  • Clutch actuator with wider diameter: gives the clutch lever a softer, more responsive feel.
  • Stiffer clutch cover: improves operation and produces a more precise bite-release action.


  • New ZF Sachs (ø 48 mm) fork with new adjustment system: allows positioning of the compression, rebound and spring preload adjusters on the upper fork cap; they can be reached while sitting on the bike and do not require tools. The fork also benefits from a new packing system which ensures greater stability and a slider with special anodizing that reduces friction and increases durability.
  • New fork clamps (yoke): stiffer and lighter.
  • New fork guards: designed together with the shoe to combine practicality and design.
  • Fully redesigned ZF Sachs shock: with more compact ø 46 mm piston, about 300g lighter. The new piston has been designed to ensure more stable operation as the oil temperature varies and increased sensitivity to enhance comfort and traction. The small upper base and reservoir have also been redesigned to rationalize the system and minimize weight and bulk. New spring is also lighter.
  • New graphics and colors.
