Crankshaft Stage6 HPC 45mm stroke / 90mm connecting rod Euro 2

High-quality tuning parts from Stage6: Crankshaft Stage6 HPC 45mm stroke / 90mm connecting rod Derbi Euro 2 (EBE050), perfect complement for racing and high-end racing cylinders.

Tuning specialist Stage6 developed this High Primary Compression (HPC) crankshaft especially for the Stage6 88cc cylinder kits (Big Racing + Streetrace).

The crank webs of this top quality full-circle crankshaft are slightly lighter, and together with the light alloy balance weights the balancing of this crankshaft is excellent. The connecting rod, specially designed for this crankshaft, offers significantly higher strength since it is 14 mm wide (instead of 12 mm); this reduces bearing wear while increasing stability even at extremely high speeds.

In this version, the connecting rod is 90mm long / for 45mm stroke.

This HPC crankshaft was built for tuned engines, and as a matter of course the Streetrace & Big Racing 88cc kits are not the pnly cylinders this crankshaft can be used with. You can combine it with all racing and high-end racing  cylinders that have to be run with a 45mm stroke crankshaft.

We recommend the installation of new crankshaft bearings, new oil seals and the use of the high quality Stage6 gear oil. You’ll find the recommended products at the bottom of the page.

Примечание:

• The crankcase must be milled open a little so the connecting rod can operate smoothly. Please check before assembly if and where exactly the case will have to be machined.
