High manufacturing quality, CNC finish.
The levers also fit on Vespa PK S and PK XL1 models (not for XL2 models with choke lever on handlebar).
For use in PK models, the lever must be supplied with a washer in the holder at the top and bottom. The PK lever mount is slightly wider than PX and with a 1.5mm washer at the top and bottom it is almost free of play.
