Stage6 Crankshaft R/T 44mm Stroke 85mm Conrod (Aprilia, Piaggio, Vespa 50)

Stage6 Crankshaft R/T 44mm Stroke 85mm Conrod (Aprilia, Piaggio, Vespa 50)

Description: Stage6 Crankshaft R/T 44mm Stroke 85mm Conrod for Aprilia, Piaggio 50, Vespa 2-stroke engines. Now available: the 44 mm R/T long-stroke crankshaft from Stage6 in the optimized Pro-Flow design. Available with 90mm forged conrod. Just like the other R/T crankshafts, this one also has a reinforced 18 mm conrod journal, silver thrust washers, and high-quality Torrington silver cage bearing. Furthermore, the vario-side taper has been reinforced to 16 mm and can thus only be used with Stage6 Oversize, Malossi Overrange, or Polini Evo Vario with the respective vario hub. Included in the delivery are two conrod bearings to allow for mounting pistons with 12 mm or 13 mm pins. The crankshaft, therefore, makes it possible to use the large-displacement R/T cylinder and also provides a bargain alternative to Malossi's BigBore crankshafts. Attention: The spigot mouth diameter for the crank webs in the crankcase is 77mm!!!

NOTE: This does not include crank bearings, sold separately.

Temperature Modification May Be Required: You'll need to heat the aluminum crankcase area where the crankshaft bearing side will be placed, in order to fit immediately the freezing Polini Crankshaft bearing side. Users assume full responsibility and risk doing so using this Polini Crankshaft.
