Will a 190 fit on the 1125 and if so, will it affect its handling and cornering abilities much? | ||

Short answer is: Yes and yes. There are quite a few threads relating to tires as I'm sure you're aware. Kinda like 'which oil is best?'. The profile will affect handling more than the size (180 vs 190), IMO. What are ya thinkin' as far as brand? | ||

Dunlop Qualifier or Michelin Pilots | ||

I ran a Dunlop D211 GPA last week end in a 190 and it worked well.It clears the stock can but not the Drummer with no weight on it.That has been fixed and Kevin is a great guy to work with! | ||

Thanks NM I might go with the Dunlop. I wonder how long it will last me. The stock Corsa III tires flat spot really quickly | ||

As far as the wider tire, I wouldn't do it if you are the type of rider that gets down to the edge of the chicken strips. I did it on my XB9 and did not notice much handling difference but the power of the 1125 makes it too touchy. I took it off early. The michelin pilot road3 takes a long time to flat spot and handles amazing. Amazing enough I wouldn't take it off to do a track day. I got over 10k out of it riding the corners aggressively. Several sportbikes in my group are running them now. | ||

The one thing I'd keep in mind is that if you switch from 180 to 190, there will be an effect on chassis geometry. Before you switch over, put old and new tire side to side and compare overall diameter. In general, a 190 will have the effect of raising the back end. To get back to neutral geometry, you will need to either lower the rear (adjust rear shock), or raise the front (lower fork tubes in the trees) or some combination of both. A 190 is not necessarily wider than a 180, but will be taller. FWIW, I have run both Dunlop Q2's and Pirelli Superbike Pro in 190 for track use. | ||

I wouldn't suggest the D211 GPA on the street.It is a race tire and does not work well until it heats up.Works really well on the track with tire warmers. | ||

I tried a 180 on a 5" wheel and almost crapped my pants when the back end slid on me, during a track day. Running a wider tire on a rim not designed for it changed the tire's profile and decreased the amount of rubber contacting the road near full lean. So, if you're the kind of person who has 1/2" chicken strips or bigger on your rear tire, you probably won't notice the handling compromise of running a 190 on a 5.5" wheel, but if you run the tires all the way to the edge, that wider tire could cause something bad to happen. | ||

Why would you want a wider tire? | ||

I just spooned on a set of Pirelli Diablos on my 1125R. I'm able to compare the Diablo's versuss the BT016's side by side (my other bike has the BT016)'s. Same tires on same width wheels, the Diablo's are noticeably less wide and has a more V-shaped profile. I'm thinking these two tires have similar diameter though. But the handling on the 1125R is lighter now with the Diablo's than the old BT016's that were in there before. It seems the 1125R prefers the more V-shaped profile tires. Makes sense since the bike shipped with Diablo Corsa III's. My point is, going with a wider tire looks better, but it may have the effect of slowing down the bike's steering. In general, wider tires will do that. In addition, the width of your wheels is optimized for 180 size. If you put a 190 size tire on it, the tire will actually have LESS contact patch since the narrower wheel will "squeeze" the tire more. This will have the effect of making the rear end feel LESS planted. Your choice. I wouldn't waste the money. Put on 180's. | ||

Thanks for that wonderful insight guys. I guess I'll stick with the 180. Just wanted a beefier appearance in the rear but don't want it at the cost of handling dynamics. | ||

I think you are making the right choice there Snackbar64. Personally, I can quickly tell the difference in tire profile on all the bike's I've owned. I'm very picky about the handling on my bikes. Any little thing like a tendency to fall into corners or a "tippy" feeling at low speeds, annoy me. The one I hate most is the resistance to steering under braking! I will take handling dynamics over power any day. My experience with my XB12R and my 1125R is, these bikes are very sensitive to tire choices/profiles, and even tire brands. |
