Unless you are after Titanium Gold or Carbon Black-Chrome Coating or DLC (Diamond like Carbon) Coating it's just as well to purchase new if they are available.
DAM Classic Racing carries a range for Laverda, Guzzi, Ducati, and other Japanese classic like early Honda etc. and can order in most brands no problem. We haven't got everything on the shelf all the time, but they are usually only 1 or 2 days to order in.
