Are these Pirelli tires, on the CR, a bit squirmy? I feel like I am going to fall over, or be blown over, when I am riding. I have checked the tire pressure, and fiddled with the suspension setting, but I still feel less than planted when riding. Anyone else have this problem? | ||

I like the way these tires feel , seem pretty planted to me ! | ||

The Corsa III is a great tire. Something else is wrong. Set your suspension up according to the manual, ride a bit, and tell us what your feedback is. | ||

What bike did you ride prior to your Buell? The Buell is so light as compared to a Cruiser, or a top heavy inline a good side winds effect can be felt. I feel this often when I have ridden my Dyna. Don't sweat it it has plenty of lean angle. | ||

I set the suspension according to the manual, then dialed back compression, and rebound dampening, which helped some, but sometimes I feel like I am riding on ice. Before the Buell, I have owned Honda CBR's, and a Hyosung GT250R. I always felt planted on those, but for some reason, not on the Buell. | ||

I have the Corsa III's on my XB...and I love 'em... | ||

Hmm. Lack of damping would make the suspension feel pretty squishy and could be confused for tire sliding. I see it at the track all the time: less experienced riders thinking they are getting rear tire slide are actually just significantly compressing the rear suspension and the lack of damping makes the bike "wallow". In my opinion, the manual's settings for sag are a decent starting point, but the bike needs MORE damping, not less. | ||

How much tire pressure are you running?? | ||

I found the Corsa III very sketchy cold and also when they were getting towards the end of their lifespan. I only went thru one front and 2 rears, however. That's all I could stand. IMO, there are better tires for less cost. I would put up BT-016s or Q2s a couple notches higher as far as performance and value. (Message edited by fresnobuell on March 30, 2010) | ||

When you say planted, what are you referring to? Planted in a straight line? Planted when cornering? Or Planted when leaned way over? If it is just in a straight line or mild cornering, it is likely that you are just not familiar with the pretty steep rake of the 1125. Compared to just about any Honda, it will feel quite a bit twitchier but it will get around corners faster. | ||

On a less important note, the tread pattern on the corsa IIIs looks pretty lame. If you put them side by side with the Q2s--they look downright silly. I also prefer ultra sport tires that don't have any siping at the shoulder--seems to me it makes sense to get max rubber on the road at max lean angle. Just a preference. | ||

I have a set of the new Pirelli Angel ST EMS waiting to go on my 1125R tomorrow. they look pretty sick an from what I've heard they are stock on the 2010 XB and 2010 1125R. Again, just what I've heard that when they were released, Buell went from the corsaIII to the Angels. | ||

My 2010 1125r has Corsa III's on it. They feel just fine to me. Haven't touched the suspension yet. Blocking out a couple hours for that just in case. | ||

> On a less important note, the tread pattern on the corsa IIIs looks pretty lame. Because the appearance of the tread pattern is such a significant differentiator in the performance of the tire. (roll eyes) The Diablo Rosso goes full "slick" on the sides, but it's performance is no where near what the Corsa III gives. It's hard to imagine Buell putting the Angel ST as the OEM on a proper sportbike. On the Ulysses, sure, but not the 1125r. On the Buell US site, the Corsa III is still indicated as the OEM tire for the 1125r. | ||

Fast1075: 31 lbs. front, 34 lbs. rear Ratsmc: I am referring to straight line travel. It actually feels pretty planted in the corners | ||

I had the same feeling with my corsa III's. The bike felt like was going to wash out from under me. I switched to pilot lower 2ct's and never looked back!!! A friend told me the rep says to run the corsa's about 3-4 psi under the recommendation | ||

My 1125CR is not squirmy at all, in fact it feels surprisingly planted. I find very little to fault about the handling of this bike at all. | ||

Because the appearance of the tread pattern is such a significant differentiator in the performance of the tire. (roll eyes) Just a note on the looks of the tire--notice I qualified the comment as "less important." It might be absolutely meaningless to lots of people, but for some, aesthetics IS a consideration regarding anything on their bike. Its GREAT you like the Corsa III. I personally (and lots of others apparently) happen to feel like it's an overrated, overpriced tire that happens to look like shit on top of everything else. | ||

My 1125CR is not squirmy at all, in fact it feels surprisingly planted. I find very little to fault about the handling of this bike at all. Mine feels fine at moderate turns..I don't really take tight turns at super high speeds(been only riding for almost 3yrs) but only at high speeds 130+mph the front end feels squirmy for me..maybe it has to do with my weight..152-154lbs dunno But my suspension was setup by a shop for a semi aggressive rider. It felt night & day from what the manual called for. Feels much better. I can't recall the price..but I want to say it was 50 bucks for the suspension tune. | ||

If aesthetics are what drive you, go with the Diablo Supercorsa:  Not only does it look great, but it's a fantastic tire, to boot! The SC3 is pretty durable for what is basically a race tire. The Bridgestones require setup changes to retain the 1125r's brisk handling. The front is taller which changes the bike's rake and trail, and the way the swing arm interacts on the tail end as well since it's "riding low". Also, the Bridgestones have a very round front tire, so it's going to steer slower. Some like this as it adds stability to the bike, but on a tight point-n-shoot course or road, it makes the bike a muscle experience. In terms of net cost, I've found the Bridgestone actually costs more to operate. While they are cheaper to purchase, they don't last as long. I get less than 2 full track days out of the 003, vs. 4 with the Corsa III. After the track days, I rotate them to the street bike where they last a good 400-600 miles of street use. (Here in Texas, we don't have curvy roads, so a worn out track day tire is perfect for the street.) As for pressures, I recommend the Corsa III at 32 HOT front and 28 HOT for track and 32 HOT for "street" pace. Either way, the OEM recommendation of 36R 34F is a bit over inflated in my opinion for a rider less than 200lbs. The Corsa III wants to get it's carcass flexed to put heat in the tire, so you want to run a rather stiff suspension and a lower inflation and then go at it with straight up and down acceleration and hard braking to warm them up before hitting the twisties hard. The Bridgestone is somewhat the opposite. They have such a rigid carcass you really depend on your suspension for ride, not just weight distribution like with the Pirelli. Mount an 016 on a manual tire changer and you will QUICKLY come to appreciate the flexible nature of Michelin and Pirelli tires. Food for thought. I go through about 15 sets of tires a year, and I've tried just about everything on these bikes. | ||

Okay, since we are talking about straight line, I am not sure I could find a reason to point to the tires. My guess is that the primary issue is the geometry difference between the Honda and the Buell (I have 2 Hondas right now) Hondas are built to feel stable. That said, there are things that can be done to get it to where you want it. As has been mentioned a good suspension tuner can sort all of this out. There is a small chance it is the tires but you want to sort out the suspension before trying different tires as you could be chasing ghosts going that direction. The suspension tuning is cheap and no matter what you are doing with the bike it is always a good idea, particularly before replacing parts. |
