We are constantly extending our catalogue and trying to make new, interesting products available to you - MVT Crankshaft "SRace" MBK Booster / Stunt (Minarelli vertical with 12mm piston pin) with 43mm stroke and 80mm connecting rod.
It is a full-circle crankshaft meaning that primary compression in the crankcase is increased which in turn means more torque. The connecting rod is polished, this gets rid of stress risers and reduces premature breakage. The balancing is much more precise than on a stock crankshaft so your engine will run smoother, especially at high rpm, and is more reliable.
Suitable for up to 18,000rpm. We recommend using it with racing engines (43mm stroke).
Main bearings and oil seals are not included, sold separately.
For Minarelli vertical / 43mm stroke - 80mm connecting rod - 12mm piston pin - 12x16x16mm small end bearing (included).
