[QUOTE="Andy"] You don't want a 190, you want a 180. The 9R will handle better on the narrower section rear tyre, trust me on this, I've tried both widths.[/QUOTE] Actually, I thought about that (having seen yours with the 180 fitted). Mind, the 190 was the same price as a 180 at the place I got it done, so it wouldn't have been any cheaper. This is the first time I've ridden the bike with new tyres, so I might try a 180 next time, now I've got a baseline to compare it to. Bridgestone's website only seems to recommend 190s for the 9R, mind - not that that would stop me.
