I agree, the thing about vincents is that, despite their age, they are quite capable of being used on todays roads and (assuming that the bike is in good shape) they are quite fast and fun to ride. So why not ride the damn thing! The bike has been restored so it's not like there is a hope of preserving the original factory patina, paint and parts can be replaced as long as their is enough demand for parts to be made. I for one am thankful that all these parts are available because my shadow really needed a lot of them, and for that i really have thank all the people who ride and restore their bikes and generate a need for parts, and of course the people who actually get them made, kemps, voc spares co et al.
we will see what happens.
