tyre rubbing exhaust

MARTIN H · 13-Jul-2006, 22:16

No, I stuck with Diablos both 180 and 190. I do recall noticing in the past that certain manafacturers tyres were wider than others for any given width. I think Dunlops were always wider (or appeared so) than others. If the tyre is slightly wider than another make it makes sense that if its profile whether it be a 50 or 55 is accurate then the rolling radius of the tyre will be larger and so nearer to the exhaust.

I spoke to a few people when I had trouble with mine and nobody has heard of this problem before. JPM reckons I must have a short wheelbase 996R!

well i cant really make much sense of it, as thinking about it the bostrum rep 998s came with dunlop 208s or were they 207's anyhow the problem exists.

potential soloution of a 16.5 rear rim being considered

had similar problem with tyre not cleraing hugger but that was defo hub positioning....it was at 7 oclock not 4 oclock...just chnaged from 180 to 190 so I'll have a look later, might explain why I'm so slow of the tyres rubbing

Are you running a full 998S exhaust, or 998S downpipes with a different link pipe and cans

What tyres are you running???? if it is a Dunlop then you will find that it grows when hot and used at speed due to the profile of the tyre & it will rub the exhaust even a 45mm system, try a differant tyre & see how you get on.

the doner bike was a 748r i took the engine out and fitted a 998s engine.
i used the 520 chainodf the 748r. now running 14-37 sprokets so as it clears.

I remember reading somewhere about differing lengths of swing arms on some of the ducatis. Not much in it, only mm, prob enough to make a difference. I also recall that the exhausts were different too on the 748r...ill see if i can dig out the info from my library at home.
