First 150 mile on the new Michelin pr4's yesterday. Faster turn in, rear seems to sit higher, and its not just the new tyre. Still feel a little harsh on the front but not as bad as the Bridgestone's, I'll play about with the pressures a bit, just running 36 42 the first time out. Greased up the rear link while the wheel was out. I'm getting that 1-2mm rear vertical play in the link now, 18k miles. No mot here till 4 years so ride on.
