- Main advantage: increased torque and power without additional modifications.
- Usage: lightweight upgrade, enduro/cross, improving engine responsiveness at low and mid revs (depending on installation and settings).
- Contents: supplied with two complete sets of shims for precise timing adjustment.
- Installation advice: installation recommended by a professional with the appropriate tools and skills.
This Stage 1 is perfect for those seeking more performance without radically transforming the machine. Follow the installation recommendations and shim timing to get the best out of the camshaft while maintaining reliability.
