Crankshaft -TAMENI Racing (rotary valve)- Vespa V50, PK50 S (Ø=19mm cone)

Crankshaft -TAMENI Racing (rotary vane)-
High-quality racing crankshaft with extended intake timing to get more mixture into the cylinder per crankshaft revolution. This increases power across the entire rev range and allows the engine to rev out further. Especially in connection with high revving cylinders a good measure to mobilize the full power and to be able to use larger carburetors from 19mm sensibly on the smallframe with less stroke.
In addition, with the racing shaft, displacements over 100ccm can also be fed reasonably with mixture.

TIP:

For cylinders from 75cc displacement directly order a wider upper connecting rod bearing!
