Details44 mm R/T long-stroke crankshaft from Stage6 in the flow-optimised Pro-Flow design. Available with 90mm forged conrod. Just like the other R/T crankshafts, this one also has a reinforced 18mm conrod journal, silver thrust washers and high-quality Torrington silver cage bearing. Furthermore, the vario-side shaft has been reinforced to 16mm and can thus only be used with Stage6 Oversize, Malossi Overrange or Polini Evo Vario with the respective vario hub. Included in the delivery is a 14mm small end bearing. To be able to mount pistons with 12mm and 13mm small end bearings, you will have to order them separately. The crankshaft makes it possible to use the large-displacement R/T cylinders and also provides a bargain alternative to Malossi’s BigBore crankshafts.
Attention: 44mm stroke and 90mm conrod
The crankcase will have to be opened up to 76.6mm! The shaft at the variator side has a 20mm diameter so that Piaggio engines require a special oil seal, which is included in the kit!
