You're looking for maximum power? Bidalot has it - Bidalot 80cc Tuning Kit Racing Factory 80-B 2015 Derbi Euro 2 including cylinder + crankshaft.

The kit includes:

  • Cylinder (stroke=44.9mm / conrod=90mm) with 6 transfer ports and bridged exhaust port
  • One-Ring Piston, d=47.6mm
  • High-Compression Modular Cylinder Head
  • HQ Racing Crankshaft (44.9mm stroke / 90mm connecting rod)
  • Gaskets for mounting

The crankshaft included in this kit is of superior quality and has a 44.9mm stroke (note - 90mm connecting rod), which, in combination with the 47.6mm piston, will result in exactly 80cc displacement.

With plenty of torque and plenty of power throughout the entire rpm range, this 80cc Hyper Racing kit can be used for track as well as for drag racing.

To unlock the full potential of the Bidalot 80cc Tuning Kit Racing Factory Derbi Euro 2, we recommend combining it with a large diameter carburetor (minimum 28mm), a Bidalot Factory 2015 exhaust and a Bidalot Factory or Stage6 R/T digital internal rotor ignition.

NOTE: you'll have to mill in the crankcase to make room for the 44.9mm crankshaft and the cylinder skirt (see instructions in manual).
