When Paul Young tested the 190 rear he said it didn't suit the bike and he was slower with it on. That was a Pirelli 190 rear. I've always stuck with the 180s with me running the Pirellis or Metz but this year I have a set on Dunlop D212 GP Pros to try in a 190. Not tried em yet but the first thing I have noticed is how much taller the front is. The tyre is still a 70 profile but rubs on the mudguard (fender) and thats before its hot and expanded at speed. So I've had to ditch the front mudguard for testing in two weeks time in Spain. I'll report on the tyres when I get back.
Anyone got a quick fix for the mudguard?

With the taller rear tire raises the tail, reducing your rake and trail. That's why it seemed to "turn in" faster. Not necessarily a good thing.

Less rake and trail = less contract patch = less feeling = crash!

Dunlop claims no expansion. I don't have any issues of rubbing when they are up to temp. It IS a squeeze with warmers. lol

Mudguard fix: You can get new bolts with finishing washers. You'll have some play like 3 or 4 mm... not to much but some. You could also try to ream the holes a little on the bottom. my .02

Ditch the little plastic fork protectors. Then you'll be able to lift the mudguard up a few mm. Sounds odd, but it worked on my bike when I got D211s and the front rubbed.

I'm super-curious about how your 190 goes in testing.

Well too late now I actually grabbed a set of warmers from a member here for a 180 because it was a good deal.

From what I hear they are THE DOT tire to run although I really enjoyed my Supercorsas on my Ninja in 190 size.

If I didn't already have a spare set of DOT race Supercorsas in 180 size sitting in my garage I would've purchased a set of 190's.

I have tried lifting the mudguard on different bolts etc and removing the guards. Still no joy. I've made a new mudguard up and drilled the holes as low as possible and it just clears but when you get any rubber or grit on the tyre as you come back into the paddock it rubs like buggery on the mudguard. I'm now making a completly new one which will be flat on the sides, brackets on the fork legs and a couple of Dzus fastners inbetween it all to hold the mudguard on. Wont have time to get it done before testing though :-(
Thank you for your inputs guys.
