The 52mm EVOLUTION crankshaft by bgm is a low-price alternative to the MALOSSI HPC crank. This racing crankshaft is made from selected materials and provided with SSC race bearings, so extreme rpm ranges should not be much of a problem. The fine balanced full circle crankshaft certainly found our strong approval, not least because of its reasonable price tag.
Fine balanced full metal HPC crankshaft, 52mm stroke, gudgeon pin = Ø16mm
Double groove con rod, double boreholes in the upper con rod bearing, crank webs fine balanced with copper and aluminium weights, continous gearing on the vario side provides highest stability
SIP TIP: Do not forget to replace the old bearings and oil seals!
