Good choice, a Jota
The trouble is, they are old bikes now, so whatever it looks like, you just dont know what the engine condition is. You really dont want to spend 17k on a bike and find it needs a 5k rebuild..I just spent 8k on wk to mine, owned since 2000, albeit that included Mikuni carbs, new conrods, pistons, crank rebuild and some other upgrading stuff..tubeless tyre conversion, modern fuse box, reworked forks etc. It is a fabulous thing now
I would call Keith Nairn of Laverda Scozia for a chat..you never know, he might know of something suitable and can price work on a bike that needs it. Hope you find something suitable, good luck with the search.I am in Kent btw.
