hey guys im new to the forum but ive been looking at the treads for some time. any ways i have a 1125cr and was wondering if any of u are running a 200 rear tire or if it will even fit thanks for any help you can give me thanks | ||

Even if it will fit the swing arm...belt, etc....which I doubt it will. The wheel is WAY too narrow for a proper fit. Think about it for a second...wider tire...requires a wider wheel...! And if you have the balls to widen the wheel, you can make the tire fit into the swing arm also. Moving the belt out..etc. Mike | ||

I 190 is wide enough to keep from spinning up the rear too much on corner exit. In addition a 200 tire is going to have slower turn in than a 190. Therefore, style, if you even like the looks may be the only reason for a 200, at a detriment to performance. Just my thoughts. Sorry for not really answering your question, but 200 vs. 190, makes me have a question too, why? Jay | ||

And by proper fit u mean that it would not ride properly or that it could not be mounted | ||

I think, by proper fit, he means that if you try to fit too large of a tire of a smaller than desirable width rim, you're going to change the tire profile. | ||

Two weeks ago at my last race day I switched from a 190 back to a 180. Not only does it feel better it's faster in the corners. Controlling wheel spin is why they make the throttles adjustable. Also, last year Ronnie Saner the crew chief for the Latus race team told me to ditch the 190 and go back to a 180 for better lap times. I guess if you're just running a bigger tire for looks it doesn't matter. If you do get that 200 put on a CR, please post pics. I'm sure it would look bad ass and I'd definitely want to see it. | ||

I saw that with the 190 I have a choise between a 50 or 55 is that just height? And yes I do like the looks of a fat tire but I do ride pretty aggressive so I don't want to sacrifice ride quality to much | ||

the 50 or 55 is the aspect ratio. its the percentage the sidewall is of the tire width. so if you get a 190/50ZR17 tire your sidewall is 95mm, and if you get a 190/55ZR17 it'd be 104.5mm. The stock tire is a 180/55ZR17 so the sidewall is 99mm on a stock tire, which is right in the middle of the 190 options. you either lose 4mm with a 190/50, or gain 5.5mm with a 190/55 | ||

Ok well thanks that clears up things bit for me | ||

Rusty374, PM sent. Tell me what you think. | ||

I have the 190/50. Good enough for fooling around on at highspeeds. Im not a track guy (yet) but for city action its fine. | ||

Any time I have ever changed a rear tire on a bike to a different size, handling has suffered. That includes going down in size--I went from the stock 190/50 to a 180/55 on my GSX-R1000 and it made the bike more resistant to turn-in and require more effort to hold a line mid-corner. On the other hand, I have gone from a 120/60 to a 120/70 on both my CBR600F2 and my SV650, and both times was happy with the change--turn in was quicker and the bike felt more stable when leaned over due to the fatter contact patch from the taller aspect ratio. The only reason I can think of to go with a wider rear tire is aesthetics since it negatively affects performance. If you prefer looking good and going straight over better performance and twisty roads, then get a wider rear. Otherwise stick with a stock-sized rear. | ||

I had the opposite experience on my 04 GSXR1000. When I went from a rear 190/50 to a 180/55 I noticed it turned in slightly quicker. (Slightly narrower, but slightly taller.) | ||
| Thefleshrocket |
Kidder, funny, my GSX-R1000 was an '03. The main reason I got fed up with it and sold it (to one of my brothers, actually, so it's still in the family) was because it wasn't nearly as nimble as my SV650S or even my SV1000S. I could understand the 650 being more nimble since it was about 20 lbs less and had a much smaller engine, but the 1000 was about 50 lbs heavier than the GSX-R and it was still noticeably more flickable. The Gixxer still has the 180/55 on the rear and I told my brother to go back to a 190/50 once the 180 is worn out. I'll take it for a spin after that (he lives 5 hours away) and see how it feels. | ||

Well iv found out that a 200 will fit according to the measurements they gave me and they also told me because of the wheel width it pulls the tire in a little on the edges therefore the change in profile pushes the tire a little higher in the center thus making it handle about the same as a 190 | ||
| Arcticcr |
Rusty374, when you say it fits, are you taking in to account that the tire will expand at speed? | ||

They say it will be fine I'm going 2 order it next week so when I. get it on ill send picks tell u guys what I think | ||
| Thefleshrocket |
I bet you will think it will feel fine, but I think if you think that it will be because you are more of a straight-line person than a go-around-corners rider. | ||

here is my experience..... I fit a 200?55/17 on my old XB12 and it fit fine and worked very well, cleared the belt no prob. So if the rear wheel on the 1125 is the same as the XB which I believe it is, atlease if the width is the same it'll work. I'm going to be trying it out very soon. I tried a 200/50/17 and it did NOT work on the XB because the tire became square when shoving it on such a narrow rim. the 55 series has a taller side wall which lets the tire round out more instead on becoming square. hopefully everyone gets what I'm saying? I've tried it. does anyone know if the rim width is the same on a XB12 compared to a 1125? | ||
| Rieguy187 |
oh yeah and the 200/55/17 was a dunlop harley tire for a vrod that used, there is a pic on my profile still, I'm going to put one on my 1125CR | ||

When you take a tire and force it onto a wheel that is too narrow for it, it will make the tire pinched and it will have more of a U shape rather than a ( contact patch. Picture the ( rotated 90 degrees counterclockwise. What that means is that the bike will actually have a smaller contact patch when going straight. It will probably have a fatter contact patch under extreme lean angles but the bike will have a tendency to fall in when leaned away from upright due to the steep tire profile. Anyway, we can tell you until our fingers get callouses that this is a bad idea, handling and performance-wise, but it sounds like you just don't care. Fair enough, it's your bike. | ||

Knowing that the bike can hold a 240 wide tire, has anyone tried using the rear and front wheels (18") from a V-Rod on a 1125R? Is there a compatibility issue with the bearing and/or rim width for both the front and back? Haven't heard of anyone doing this, but it would seem like it should work. Any feedback would be appreciated. |
