Longstroke crankshaft Malossi 55mm stroke
This crankshaft is based on the Malossi MHR crank, whose stroke is raised by 3mm using a excentric crank pin. The original con rod is revised and upgraded with a special high performance big end bearing. Super durable!
Longstroke crankshaft BGM 58mm stroke
Starting point is a 55mm BGM crankshaft. Just like the one mentioned above refitted with an excentric crank pin.
Very special solution: The crank case has to be machined, porting timing radically reworked.
Retrofit service
Certainly you can send us your own crank shaft (even if defective) for retrofitting. This might save you some dough. |
