DescriptionCrankshaft -MAZZUCCHELLI Racing- (rotary valve) 57mm stroke- Vespa PX200 DescriptionIn order to achieve higher speeds, one should reach for the racing shaft. The extended intake timing results in a much freer engine revs. This measure is especially noticeable with high-revving cylinders. The quality of the crankshafts is very good and so they resist even the highest revs. Especially for engines with a larger displacement, they are an optimal supplement to extend the usable speed range. These engines turn out freely, which leads to a significant increase in top speed.
