Crankshaft, connecting rod assembly TNT Racing race 40mm for mécaboite driving DERBI euro 3 & 4

Here is the crankshaft reinforced in full masses TNT RACING for DERBI euro 3, 4 engine without balancer therefore cannot be mounted on DERBI GPR. It is quite simply the cheapest on the whole market with the TEKNIX model. To be mounted with an original engine or a small 50cc or even small 70cc kit!



Its balancing is quite well worked (internal machining), the connecting rod is well reinforced yet much cheaper than an origin and in full masses for more performance. The steel used is not of the highest range, the finish is not much better than an original (for the price that goes without saying). It is clearly a good little cheap vilo which offers solidity, money and performance gains.
