Features

S3 Extreme Enduro Cylinder Head Kit and Insert - Low Compression (Red) | Ref: XTR-BETARR-300-R

Designed by S3 for extreme enduro, this low compression cylinder head + insert kit is aimed at riders seeking more control on tricky terrains. Its design aims to soften the power curve and facilitate throttle modulation, allowing for smoother riding in obstacles and technical sections.

  • Improved traction and torque management for precise handling at low and mid-range RPM.
  • Softer engine: facilitates grip and acceleration over obstacles.
  • Lightweight design and refined finish: reduced unsprung weight and dynamic red look.
  • Targeted reduction of engine temperatures thanks to the optimised cylinder head design.

The kit includes everything needed for the transformation: Extreme insert, cylinder head, and O-rings. The entire set is designed to fit Beta RR 300 2T models (notably Racing, Enduro Racing, and the 2021/2019 versions listed below), providing a reliable option for extreme enduro riders and fine-tuning enthusiasts.

  • BETA RR 300 2T RACING (2021)
  • BETA RR 300 2T (2021)
  • BETA RR 300 2T ENDURO RACING (2019)

Installation is recommended by a qualified mechanic. Do not hesitate to adjust the carburation and settings to get the best performance from the low compression cylinder head.
