Product description
Racing Crankshafts play a major role in tuning. Being very aware that your crankshaft carries a major load in your motor, we??ve decided to carry the high quality shafts from the italian manufacturerMAZZUCCHELLI
. Minimal tolerances, high rpm potential, low bearing play and extreme durability are the basis for optimal motor tuning. Racing shafts offer, aside from longer valve timing, polished gas flow areas and piston rods. The chamber capacity is raised and reduces turbulence
Full Circle Crankshafts are operated with a reed valve inlet. The crankcase compression is raised, the response to acceleration is raised, and the speed range moves up. In any case, the compression plate has to be completely removed, which involves massive milling. Of course, you can let our crew in the shop do the job for you! All crankshafts are delivered with a new little end bearing!
