I never go on the motorway, very rarely on a dual carraige way, so that's not really an issue for me. So you have a 48 rear then? What size chain did you need?

I used 112 links, but it's actually a bit too long and I probably could have used a 110 as stock. Bear in mind the nekkid has 10mm extra in the swingarm. I reckon 110 links will be about spot on. (you can always order 110 and chop 2 off if needed)

A faired curvey SVS is 15/44 as standard, the nekkid curvey is 15/45.

Yes

It will with a super-open pipe

I would have thought the sportier one would have the extra tooth? Or one less due to better aerodynamics?

[yorkie_chris]

One less for higher top speed on the S. One more on the nekkid to make it more revvy and fun in town and on tight roads.

so can you if a naked chain and sprockets on an s or would there be a problem im on about one of the complete sets of evilbay for £70

[yorkie_chris]

Yes it should go on fine. However ask petevtwin how many links of chain to use, as using the 110 from the nekkid will use up 10mm of adjustment.

[embee]

The naked swingarm was longer, and the chain is an extra 2 links so it'll end up too long on an S. You can shorten the chain, of course.

As I said, you can just fit an extra tooth on the front with a standard SVS chain length, similarly I would suggest one tooth extra on the rear with a standard front will fit as well, though I haven't personally done that. One tooth either end is equivalent to putting roughly an extra half pitch into the chain wrap around (nominally) half the sprocket, so a quarter pitch out of each of the top and bottom chain runs, i.e. moving the wheel forward a quarter of a chain pitch (5/8" pitch or about 16mm so 4mm wheel movement).
