Product Description
MAZZUCCHELLI crankshafts go to the top of the class due to high quality manufacturing. Exact twist and turning resistance by this new series is made possible by using the best materials the market has to offer. All 54 mm crankshafts are outfitted with a stable connecting rod with mathematically precise partial polishing and a “Silver Bearing” (remarkably acceleration stable) for the lower connecting rod bearing. Crank webs are outfitted with additional balance wells sealed with pertinax inlets to improve gas flow. Both crankwebs have Ø 87mm. The crankshaft is available with a 20/20 or a 24/25 cone, and with a 97mm or a 105mm piston rod. The longer con rod changes timings, too. You should level out the longer stroke (51mm -> 54mm) and the longer piston rod (97mm -> 105mm) by means of a thicker base gasket!
