Crankshaft Airsal Xtrem 45mm 88cc for Piaggio / Derbi D50B0

Description

For the 88cc 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.
