Crankshaft, connecting rod assembly ITALKIT Sport 40mm stroke for mécaboite driving DERBI euro 1 & 2 except GPR

The ITALKIT crankshaft is a sport model reinforced in 40.00mm stroke (original size), it is the entry level of the Spanish brand, made in Italy, cut in the best steels and this ultra cleanly, it does not have balancing specific and not full masses either, it will be very interesting to accompany a DR or TOP PERFORMANCES BLACK 70cc cylinder, the DERBI euro 1 and 2 engine having a large low engine volume. We would however not recommend it on very powerful cylinders , it could also be interesting to refurbish an original engine. It is cut from good quality steels, it has a reinforced connecting rod equipped with an increased needle cage Ø12X15X15mm. It takes over the special lateral machining for lubrication (coupled to the lateral grease nipples of the original am6 casings at the valve outlet).
