Anyone ever run a 120/60 upfront? How did it affect the handling and turn in?

No one I know does.

I'm at 4k miles on the bridgestone S20's. I'd guess that they are at about 2/3rd's of their life, but steering is starting to get a little heavy, from some flattening in the front. I did not have that with the Q2's. My ride so far has been just commuting with a few bends, and lots of highway miles. I have pushed them where I could, and they are very much confidence inspiring. I really much more enjoy riding on tires like these, then I do on your ordinary ST tire.

I think in the dry the Q2's have the edge, in the wet, the S20's may be slightly better. Both of these tires do transitions real nice, and it's pretty easy to go deep.

Mileage wise, the Q2's actually may fare a bit better, but right now, the S20's are still slightly better priced.
most importantly, from what I recall, the Q2's handle better throughout their lifespan.
Interestingly, the Q2's started cupping very quickly to the eye, but it never seemed to affect handling at all.

All this puts me in a bit of a pickle. I'll need to buy tires in January, but that will also be the start of the more rainy side of the year here.

i think I may buy another set of S20's, since what is in my future is wet and straight, and towards May, when more mountain riding in the dry is expected, switch back to Q2's

BTW, I always run 36F, 42R. (That's psi...) (No, I'm not from around here, but when in Rome...)

Count me as another fan of the PR3's. I have them on both bikes and as I have a 100 mile round trip commute I have gotten to test the longevity of these tires. For a little background, I weigh 250lbs plus with all of my leather and my VFR is a bit of a heavy beasty at over 500lbs wet.

As my RS has been taken apart, I have my VFR and that is what this review is based on. I LOVE THESE TIRES!

I have ridden rain, cold, hot. Canyons, freeways and street. I implicitly trust these tires. I have gotten 9800 miles out of this set and while the rear was worn almost smooth in the middle, I still found that they gripped. I have ridden these tires harder than any set prior and they have never given me pause.

As stated before, I have varied my rides as much as I could and I haven't babied them. I have accelerated as hard as my bike can, I have hit the brakes as hard as I dared. I have done 300 plus miles in one day and short two mile rides. Wet or dry, hot or cold, these tires were there for me like a lifelong friend. I have scraped the footpegs on both my RS and my VFR, both times on rough old pavement and these held the road. They grip more than I am currently capable of pushing them and that is nearly knee down on the VFR. I have had them at high speed and slow speed. I can ride my bike at 1 mph ( I love seeing how slow I can go and keep the bike up without putting my feet down) or track speed. The little extra that I pay for this peace of mind and just plain fun is totally worth it to me.

Now, as to how they lasted for me. At about 7000 miles I pumped them up too much, about 38 front and 40ish back, PSI of course. I rode about a week this way and this squared them off. I dropped the pressure and hit the canyons as much as I could and this helped re-round the rear, but the front stayed squared, though not as sharply. Both the front and rear wear was fairly symmetrical, but of course the rear did have the lion's share. The reason I say it was fairly symmetrical is that on previous tires the wear rate of the front was much less than the back. Interestingly enough, the middle sides of the front were actually worn more than the middle, but again, I was pushing them pretty hard at times.

I have BT016 Pro tires slip the front, but never had I had that happen with these. I have had the confidence in these tires to increase my lean angle as well as exit speed and they just stick. I have gunned it on corner exits, while leaned over and nothing but the rush of acceleration.

At times, they do feel like they wander a small amount on the grooved California concrete freeways, but it is such a minor thing it is only something I occasionally notice, really it's really a non issue.

I have skidded the front tire at the end of a hard stop, but it always tracked straight. I even lifted the rear a little on one of my practice hard stops. Again, no drama.

Michelin has my money with these tires. I'm hooked. I do wish I took pictures of them before I had them changed, but I only had my 3Mpx phone camera and it wouldn't have been that great of photos.

If you are debating these over something else, don't. Just buy them, they really are that good.

Now, for the funny part, at least to me. As all tires wear slowly and the changes in the profile of the tires is something you automatically adjust to, I literally was laughing at how different, actually weird in a fun way, it was to go from a squared tire to normally round ones. When I was coming home I was taking it easy but there is a sorta curvy road just before my house. I had been so accustomed to the hesitation and the sort of sudden drop into a turn that only a squared tire can give you, that it was a totally new sensation for me to be on a tire that just leaned over. I could literally feel the profile of the tire and it was such a cool, odd sensation that I was literally laughin in my helmet. I felt like I was on a ride!

Changed out my PR3's. I have no clue what the actual mileage on the tire is though. I had them on for a while, switched them out with Conti Motions after rainy season last year, then switched them back once the Motions wore out near rainy season. It was 16k miles total on both tires. I doubt the Motion's made it more 6k so that's maybe 10k commuting miles. Not too shabby. There were starting to get scary in the wet, the shoulder on the front wore off most of the tread.
