Now available: the 44 mm R/T long-stroke crankshaft from Stage6 in the optimised 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!!!

Attention: 44mm stroke and 85mm conrod
