Bought this a couple of years ago from a well known European Specialist along with a Veglia Tacho for my Italian made Ducati 250 narrowcase but it has never been used, was test fitted only, as I had a change of heart and decided not to fit as I used the Rev Counter itself on another bike. It was not cheap at the time and it is very well made, really lovely looking item. The fixing screw for the drive to cover has been left long and will cut down flush once fitted. Comes with all fittings to suit drive off camshaft, check your camshaft has suitable cut outs at its end.
