Who has ran a 190 rear tire on a stock XB12Ss or similar bike? Looking into running some race tires at the track and can get a good deal on a set but the rears a 190... I am concerned about any rubbing or clearance issues with this tire. Thanks! | ||

190s work great. Many here have run them without issue. | ||

I have a 190 on my Uly and it fits fine. I got it on the cheap.... couldn't pass it up | ||

No problems with my Scg... | ||

I've had two sets of 190's and had no problems. I am, however, back to the 180's and do notice a big difference. The 180's seem to be quicker and smoother. I've run my 190's on the track also. They were on my SCG. | ||

Thanks... I am just trying to decide between brand new 180/120 Pirelli Dragon Supercorsa Pro (SC2 front and rear) race tires or a set that was used for like 4-8 laps (might've been at race pace idk but the rider said he wouldnt even call them take offs, just broken in) with a 190 rear... but that set is the DIABLO Supercorsa (SC2 rear SC1 front) which is Pirelli's latest and greatest race tire. I have never used race rubber but I hear conflicting things about how good the Dragon's are... I just think new rubber (can see how they wear initially to get the suspension set, never been heat cycled etc...) would be best and I like the idea of sticking with a 180... The 190 is a 190/55 though not a 190/50 so it shouldn't slow down steering. | ||

Be AWARE, there are clearence issues with a 190 tire on 08 and later XB models. Ask me how I know... As for race rubber on the street, just remember the race tires may not reach operating temps on the street. (Message edited by Paint_shaker on February 02, 2010) | ||

Jraice - from the 07 Pirelli catalog, the min recommended rim width is a 5.5 for the SC2, so you are good to go from that standpoint. The max width is 191mm, compared to max width of 179mm on the OEM rubber. That being said, you need clearance for 6mm more on either side of your tire. I'm assuming max width means exactly that, but you might want to call Pirelli (1-800-Pirelli) and ask if that's no kidding, max width for a 5.5" rim, hot tire. Tire height is darn near the same, 652mm's vs. 647mm's, so only a couple mm's change in ride height. | ||

Paint shaker... these are for track use only. I have Dunlop Q2's (great tires for spirited riding) for the street And Vospertw...thanks for the info but I think I'm going to stick with the 180's for now and maybe experiment with 190's in the future... Going to try out the Dragon Supercorsa Pro's and in the future try the Diablo Supercorsa (newer DOT race tire) or the new Diablo Superbike Pro that will be available in April, its a slick but with a new compound that requires less tuning for setup, wont cold tear as much and is not effected as much by heat cycling... still with the grip of a slick race tire. | ||

I ran a 190/50 for a year. I had to remove the lower belt guard, because of clearance issues. I have read, not actually seen, people having problems with the 190/55. It is a little taller that the 50 series. I seem to remember the tire hitting the front of the swing arm. That shouldn't be a problem on the Ss, because of the longer swingarm. With all that said, I just bought new tires with a 180 rear. The 190/50 had a flat profile. At the end of its life, it was getting harder to keep the bike down in corners. But, boy do like the way the 190 looks. | ||

You're screwing with corner-carving geometry by going to a wider rear tire. The wider rear tire will affect turn-in and steering effort. (although the affect is admittedly less pronounced on the longer wheelbase Buells.) Think about the tires' centerline. The more you lean over, the more off-center the rear tire becomes. (relative to the narrower front tire.) A wider rear tire than OEM will exacerbate that off-centeredness, and the trait is already prominent with OEM Buells; no point in making it worse. You'll be forced to counter-steer harder to counter the increased off-centeredness. You lose more with a 190 than you gain. Those fatter tires can easily seduce; its best to resist. On a bike with such favorable power delivery, it isn't a matter of traction, but rather handling that'll produce the edge.

You'll have to re-set your ride height because of the nearly 3/4 inch rise in the rear. If you think steering is interesting now, just wait until you put a 190 on the rear (steepening the front more). If you don't have a ride-height adjustable shock (Ohlins or Penske or Elka) - you can try pulling the front end up on the forks to compensate. (Message edited by slaughter on February 07, 2010) | ||

Thanks guys... Going to stick with a 180. Will be running Dragon Supercorsa Pro SC2 race compound front and rear. If I can get one of the new trackday compound rear's I'll run that with the SC2 front (easier setup with the trackday compound which would be good on my local left turn biased track which eats up tires quickly with any setup that is not 100 percent perfect). |
