I had them on my RD. They were really great, and confidence inspiring when they were new. The front tire developed a weird wobble when there was still a lot of tread left. Something in the casing must have parted. Considering what they cost, I was pretty disappointed and when I replaced them, the back tire was pretty worn at that point, I got the BT45s. I'm pretty happy with them, but the sizing is very small. The 90/90/18 front tire I have on there now rides great, but looks like it belongs on a moped. If I were to do it again, I'd get a 100.
On my /5 i finally wore out the Lasertech that had been on it for years, and by the widespread recommendation on here, I got the Michelin Pilot Activ. VERY happy with it! I look forward to getting the rear to match.
