Sigh, that's how some of these internet romances go. One day you're hot, the next you're not. Such is the fickle heart.

I almost sold my 2011 because of a high speed wobble that I got after I hit a softball sized rock and blew both tires and rims. The wobble wasn't there before, and now it wouldn't go away, happened at about 130mph plus. I finally figured out that it was the PR2's that I had put on after the crash, they were much "thinner" than the B-023's that came with the bike. After going back to the B-023's, the bike is dialed in at 150mph and I am glad to say I'm keeping my girl (Connie.) If I didn't want to ride at those speeds, I would've bought a bike that didn't share the same engine as the zx-14!
Interesting.  You are suggesting the PR2's have a stability problem. That is heresy on this forum. As far as I can recall, in 5 years only you, me and one other has ever posted anything negative about the PR2. By the way, I also blew a front rim hitting a softball sized rock.

I think what he is posting is that he had a problem with one set of PR2s.
As for the heresy, I think you'll find that most of us PR2/PR3 devotees will abandon them as soon as something better comes along. I know I will.  ;D

Personally I haven't tried the BT023s as I haven't needed to.
I changed from the BT021 because they were not just bad, but bordering on dangerous.
A great many other people agreed whereas I have only heard of a few people who prefer the BT021 over the PR2.
My personal experiences of the Exedras, BT45, BT-020 and BT021 have led me to the conclusion that Bridgestone don't make tyres for me. They seem to sell enough so I guess that some people like them.

In the past I was a Metzeler Z6 devotee on the C10 and before that I was an Avon Azaro devotee and before that a Michelin 89/90/100 devotee. I go where the performance is. I'm not a brand junkie.

I once broke a rim by ramming it into the side of a Volvo 240 at 60Mph. Does that count? <LOL>

What's up with you guys? Target fixation? You're supposed to drive AROUND those rocks.  :o

In my case it wasn't target fixation, I never saw the rock. More like looking in the wrong place, gazing at the scenery, getting cocky on a familiar road, failure to follow sipde. GONGGGG!

I've often wondered how the sponsored pro's actually avoid target fixation

I think a lot of things could cause a high speed wobble. I was at about 135mph on Thursday afternoon. I did it with a quicker acceleration than I usually would and in 4th gear which is also rare. I let off the throttle and wobbled hard. Let off the throttle just a bit more and shook worse and doubted saving it. I immediately throttled upward closer to 140mph, pushing hard out on both bars and let off the throttle a little slower this time. And all went good. Thank God!
I think it had a lot to do with the 200 lbs of work gear and the rate of forward pressure when I started to slow down. I'll have to open it up again when I have a lighter load on it. This was the first time I've ever had issues at high speed.
I got home and did an oil change on me and the C-14. We feel better now.

Wow, if I rode two up at that speed, it would be the last time she rode with me, ever!    :o

I have a C-Baileys Euro and it was in the down position. I leave it down all the time this time of year unless it is pouring out. I won't go over 120 again until I have a lighter load, so I can get a better feel of what is triggering it. I did have an extra compression bag tied to the back seat with a cargo net. But I still am thinking there was too much forward momentum to let off the throttle that hard.
I have hit 150 with the screen up on my old bike 2008 C-14 with no issues too.

Running with a light load in the bags (prob. 200 #'s of man and gear), PR3's, stock windshield in the down position, pretty calm day, hit 135 mph and cut the throttle. Experienced a wobble. That's the second time it's happened in pretty much the same scenario since getting the PR3's. Never happened with the OEM's.

I might start blaming the PR3s as well then. Although I do love them.

Those experiencing the PR2/PR3 high speed wobbles, would you reveal if the rear tire is a 50 or a 55?

I have PR3's and zero wobble. The bike is rock steady at any speed. 27,000 miles on a 2010.

- imho , at very high speeds , the rider's position/posture on the bike is very important.

- elbows bent , forearms parallel with the ground and a light hold on the grips.

- try that and let the bike do her thing
