§ Crankshaft, connecting rod assembly BIDALOT Racing Factory long stroke 44.90mm for mécaboite engine DERBI euro 3 & 4

Normally reserved for the BIDALOT RACING FACTORY 80cc high engine, you can obviously use this crankshaft on other high engines. This crankshaft is really of very high quality, BIDALOT has selected the 44.90mm stroke as the most appropriate, the connecting rod and the silks (worn) are of original size, therefore 90mm and Ø20mm.

This vilo is obviously cut in the best steels (based on forged blanks) and has undergone several treatments. It is very well balanced (you need to preserve the original balancer / balance shaft with this linkage).

It is equipped with an ultra-reinforced connecting rod machined in the mass / polished finish with increased / studied lubrication holes. The big end cage is increased, that of the feet also with a size of Ø12X17X16mm against 12X15X15mm of origin for less friction and more solidity.

The connecting rod obviously rests on an increased crank pin with honeycombed anti-friction wedges. Really a real and beautiful exceptional piece reserved for the most passionate and connoisseur among you.
