An excellent PARMAKIT Racing brand crankshaft, reinforced with full semie masses, designed for maximum pre-compression with large diameter kits, in 44mm long stroke, 90mm connecting rod, for Ø12mm piston pin, it will therefore increase your displacement (unless you have an original PIAGGIO / GILERA 75cc motor scooter). You will need to assemble it with the kit provided for this purpose. The 90mm connecting rod (long) certainly reduces pre-compression but greatly reduces wear on the piston.It is very well balanced, its bristles (bearing housing) are of original size.
However, you will have to machine your crankcase in order to pass it. It comes with its reinforced needle cage, it also has an ignition key which is already adjusted in relation to the long stroke for more performance, the connecting rod is really reinforced to the maximum and over-lubricated. is specially designed for the large diameter 50mm 85cc kit for long stroke but you can use it on another cylinder with a 12mm axis if you wish, however be careful, the 90mm connecting rod with another kit will surely cause you a problem, you will need therefore install a shim or several base gaskets to perfectly adjust the height of the cylinder.
