Crankshaft -TOP RACING Evolution- Piaggio 50cc 2-stroke
Part no.:
BGM034023
Description
The TOP RACING EVOLUTION crankshafts are racing shafts of the highest quality.
The completely forged shafts are finely balanced full metal shafts. Both the crank webs and the connecting rod are forged. This gives the shaft an unbelievable resistance.
In order to achieve the highest possible weight, enormously important for a low-vibration engine run, the shafts were not provided with plastic paddings. Instead, the crank webs were designed directly as solid web shafts. It may not look as colourful, but it has only advantages.
The solid cheek shaft, by increasing the precompression, results in a better filling level of the cylinder over the entire speed range.
The bearing is in no way inferior to this top quality. Thus the SSC racing bearings resist even the most extreme speed orgies. The double slotted conrod with silver cage, as well as double lubrication holes in the upper conrod bearing, is able to withstand even the most brutal continuous loads.
The holes to achieve optimal balancing are balanced with copper and aluminum weights.
Thanks to its very high weight and the selection of the balancing weights, it achieves a first class running culture.
