Description

High quality racing crankshaft with extended intake timing to get more mixture into the cylinder per crankshaft revolution. This increases the power over the entire speed range and the engine can continue to rev up.

straight in conjunction with high-revving cylinders a good measure to mobilize the full power and to be able to use larger carburetors from 19mm on the Smallframe with less stroke.

In addition, with the racing shaft, displacements over 100ccm can also be fed with mixture.

TIP:

For cylinders from 75cc displacement onwards, order a wider upper connecting rod bearing directly! (see Accessories)
