Stage6 HPC Crankshaft MBK Booster / Stunt, HPC (High Primary Compression) crankshaft for 12mm piston pin.

HQ full-circle crankshaft for higher primary compression in the crankcase. It is entirely made of hardened steel, with reinforced connecting rod. Stage6 opted for a full-circle design instead of the standard design with inserts; this way the crankshaft has greater rotational inertia at high rpm. Excellent balancing (45%) reduces vibrations that stress materials and may lead to engine failure.

 It is suitable for 50cc and 70cc racing and even "Hyper Racing"engines. We have had excellent experiences when combining it with our MXS 70cc racing cylinders.


  • excellent balancing
  • full-circle
  • reinforced connecting rod
  • 12mm piston pin
