Yeah the standard sizes work very well, albeit that the world has moved on and most manufacturers aren't developing new rubber in those sizes.

Get yourself a pair of Dunlop GPR70's if you want sommat sticky, or GPR80's for something that will last a bit longer. The 70's are good enough to get the fairing and exhaust down on...
