I think Twin Works make a spacer kit for the GSXR1100 wheel, which as far as I can tell has the same dimensions as the second version of the Bandit 1200 wheel, which is the one I'd use- the first ones had slanted spokes, teh second one looks identical to the SV one.
I've got a pair in the garage which I've been supposed to be making a spacer kit for for about 6 months, but something always comes up
You've got 2 choices with sprockets- either use the Bandit 1200 set entirely, which would work I think (I'm sure the front sprockets will fit, though I've never done it) but the only drawback of that is that it's a heavier 530 chain, the SV doesn't need that. Will you notice? I doubt it frankly. The chain length and tooth numbers are ideal for the SV. So there's the cheap option if it works. Alternatively, Renthal among others will make you a Bandit sprocket in a 525 or 520 pitch- 525 is standard for the SV, 520 is for people whowant a minor weight reduction and don't mind losing chain life.
Rear disc off the SV fits.
