Lambretta Crank pin 22x22x22 x 41mm, 3rd oversize, Race-Tour MB

Lambretta crank pin to suit most of the latest Lambretta GP crankshafts with a 22mm crank pin hole to tighten cranks up on assembly.

This is extra oversized in the crankpin area for loose crank which keep spinning.

These are 41mm wide offering more interference fit tightening up the crank webs to help stop them from spinning.

These are ideal for Yamaha 110 - 115mm con rods and Rotax 120mm con rods, with a 16mm wide big end bearing using 0.5 - 1.00mm crank shims.

With the slightly wider pin its always best to check the gap between the crank and mag housing on assembly.
