Description
Stage6 HPC crankshaft stroke 45 and connecting rod 90mm for Minarelli AM6 engines.
The manufacturer Stage6 developed this high primary compression (HPC) crankshaft especially for the Stage6 88cc cylinder kits (Big Racing + Streetrace).
The crank arms of this crankshaft, of the highest quality, are lighter and together with the lightweight alloy counterweights, the balance of this crankshaft is excellent. The connecting rod, specially designed for this crankshaft, offers significantly greater strength as it is 14mm wide (instead of 12 mm); this reduces bearing wear and increases stability even at extremely high speeds.
Features:
- Connecting rod: 90 mm (original 85 mm).
- Stroke: 45 mm (original 39 mm).
- Pin: original (12 mm).
- Needle bearing: 12x17x15mm.
- weight: 1320g.
- Maximum RPM: 16,000rpm.
- 20mm shafts
It is recommended to always install new bearings when you modify the crankshaft.
Attention:
- Most Minarelli AM6 cylinders come standard with an 85 mm connecting rod. You must compensate for the height difference with a 5 mm spacer (except in Stage6 cylinders).
- The crankcase must be milled slightly to open it; calculate precisely in advance, place the parts and mark the correct dimensions on the case so that the passage of the connecting rod is clearly visible.
Attention! You must carry out balancing checks before installing in the engine, since manufacturers deny warranty for any balancing fault found after installation.
