I'm wanting to buy some racing tires. I was directly looking at the Dunlop gpa, but they only come in 190's..so now lets  so now are 190's ok to use with the 1125. Will the 190 rear affect handling...what other racing slicks should look to use. I'm currently using pirelli diablo rosso corsa. Love the tires but i'm riding to hard on the track not to buy into the safety of racing tires and warmers. Where should I look to buy these racing tires? I got to fill and see first hand, the rear end coming around. It turned out to be a violent ride almost high side, getting her straight.. Thanks mike | ||

A few years ago when Latus was still running 1125's Ronnie Sanner (who is still the crew chief for Latus) told me to always run a 180 on my track bike for handling reasons. YMMV | ||

Where should you look for racing tires? I always get mine at the track. I trust them more with balancing and taking care of my wheels. | ||

wow, soon as you get to the track, theres sign in, tech then riders meeting. First bike on the track 10 mins after the riders meeting which leaves no time for having the tires mounted. So what's the trick! lol | ||

Apologies, I didn't see anything in your question about a street tire that you could ride to the track and use for trackdays. I thought your question was about where to buy track tires. What exactly is your question? In the top line of your OP there is reference to something like a question ("so now are 190's ok to use with the 1125."), but there is no question mark. Is that a question you are trying to ask? If yes, my first reply stands. About the 8th sentence in your OP (it's hard to tell from your grammar exactly where your sentences start and end, so I'm only guessing on the count) you said "Where should I look to buy these racing tires?". I assumed this was also a question that you were posting so I included my second reply. For me the answer to the trick really is to buy them at the track. You get the freshest tires because people at the track buy more track tires than street riders at some place like Cycle Gear or a motorcycle dealer so stock is turned over more often, and the best advice I've ever gotten on which tires to use on the track was at the track. So, what really is your question? | ||

Thanks for answering my questions to the best of your ability. Yeah I have learning disabilities. Its always tough to express my thoughts and questions threw words. (Message edited by 1125rcya on July 30, 2012) | ||

Sorry to hear about your disability. It wasn't evident in the sarcasm of your first reply. Good luck with your trackdays. | ||

Race DOTs or slicks can be purchased at the track or from the vendors that go to the races (some are online). If you are not racing, race DOTs are probably all you'll ever need. 190 vs 180- A wider tire will obviously affect handling. To what degree and if you are able to tell I don't know. I've raced both and although I found the differences subtle, I am happier on the 180. What is your level of track experience? Race DOTs or slicks will not automatically keep the rear from coming around. There are many factors to consider. Is your suspension set up properly? Do the tires have the proper PSI? Are the tires worn? Are you getting on the throttle too early? Are you on the race line? Is the bike at the proper lean angle? All things to consider. FWIW, Race DOTs start about $310 a set and generally include mounting and balancing if purchased from the vendor at the track. (Message edited by Paint shaker on July 30, 2012) | ||

I have a picture somewhere of what a gpa looks like on the stock swing arm, it's not pretty. I don't you or your bike and you don't have mods listed in your profile so again I caution you about the gpa's and a stock 1125r swing arm. | ||

Be careful of the construction if you're running a belt drive. The 190 CAN rub on the swingarm. If you have the chain, it's no sweat. Some of the Dunlops have more flexible construction and will expand more at speed. | ||

Oh yes... not sure on the 1125s, but 08 and newer XBs can NOT use a 190 rear!! It will rub enough to cause the oil tank portion of the swing arm to fail!!! Don't ask how I know this... lol | ||

The XB with chain drive does well with the 190 (and ride height adjusted with a "real" shock) - but yeah, I'd bet without adjustable axle, it'd be impossible. I race the 190/55 on the XB - but my axle is a full inch farther back than stock (for handling). |
