crankshaft Airsal Xtrem 45mm 80/88cc for Minarelli LC

For the 88cc / 80cc Big Bore cylinder kit from the Airsal Xtreme series, Airsal offers this 45mm bore crank. 45mm bore means the crankcases need to be altered slightly, otherwise the crank cannot rotate freely.

High alloyed 18NiCrMo5 steel, hardened using a special process. High compression and silver needle bearings provide excellent running up to 16,000 RPM. Great balanced crank for high end performance engines.

Made in Europe. Reinforced design means a separately available set of variator sleeve and fittings is required.
