Crankshaft Stage6 R/T BIG BORE 44mm Stroke - 90mm Conrod

44 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 taper has been reinforced to 16mm and can thus only be used with Stage6 R/T 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 bearing, you will have to order them separately. The crankshaft makes it possible to use the large-displacement R/T cylinders.

Attention: 44mm stroke and 90mm conrod
The crankcase will have to be opened up to 76.8mm! 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!
