The image below shows short-stroke Norton crankshaft.  This 80mm stroke crank is made by modifying a Triumph crankshaft.  The stock Triumph spline is used for a Triumph drive gear (not supplied).  If a belt drive is being purchased ask for a Triumph drive gear to go with your Norton clutch.  Main bearings are ground at 30mm to match Norton main bearing sizes.  This crank weighs about 5-1/2 pounds less than a stock Norton crank. This one-off 80mm Short-stroke Norton crankshaft is $1000 USD. Another one will not be made.
