TOP RACING Evolution crankshaft for Piaggio 50cc 2-stroke
The TOP RACING EVOLUTION crankshafts are racing shafts of the very 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 incredible durability.
In order to achieve the highest possible weight, which is extremely important for low-vibration engine running, the shafts were not fitted with plastic paddings. Instead, the crank webs were designed directly as solid shafts. It may not look as colorful, but it only has advantages.
The full cheek shaft increases the pre-compression, which results in a better filling level of the cylinder over the entire speed range.
The bearings are in no way inferior to this top quality. The SSC racing bearings can withstand even the most extreme speed orgies. The double-slotted connecting rod with silver cage and double lubrication holes in the upper connecting rod bearing can withstand even the most brutal continuous loads.
The holes are balanced with copper and aluminum weights to achieve optimum balancing.
Its very high weight and the choice of balancing weights give it first-class smooth running.
