I've installed these on my laverda and am happy with them on that bike (the GPS speedo is cool - cost me about $450 for the pair delivered), but don't think i'd put them on my Norton. the laverda has ND gauges - funky sort of modern looking jap things things, at least by 70's standards - where as the veglia and the smiths are much more classic - the green globes are really one of the best looking instruments on a british bike thats not a chrono. if they give up the ghost (and mine have), you can get them rebuilt to a high stand for below the cost of the speed hut units - but call me a traditionalist all that glitters isn't gold :roll:
