This is a VERY high quality, complete crankshaft for original type Italian, Indian or Spanish Lambretta engine casings. It has a HUGE 62mm stroke and is fitted with a 110mm conrod.
The casing will need to be reemed out to fit the crank but this is a simple job for any specialist scooter or engineering shop.
If you want a torque-monster engine, using a standard type casing, then this is the crank for you, period.
