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

A competition crankshaft from PARMAKIT RACING for motorcycle DERBI Euro 3 and 4. This crankshaft is in original race (40.00mm) with an original connecting rod size 90mm. Thanks to its extra large connecting rod, its increased crank pin and its ultra reinforced cages, this crankshaft will withstand your most efficient kits without worry. The connecting rod was mounted on anti-friction wedges. The lubrication has also been revised as much as possible. Thanks to its full masses, it will increase your pre-compression and therefore performance. It has a keying to facilitate the installation of the ignition. The balancing is very good (balancing marks by internal machining). The masses are cut from a high-end steel like all PARMAKIT crankshafts.
