Crankshaft Airsal Xtrem Hub 44mm

For 88cc / 80cc Big Bore cylinder kit from the Airsal Xtreme series, Airsal offers with 44mm bore crank. The 44mm 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.
