55 Wide Tires ?

Hi there everybody, i was wondering if you could help me with a question i am wanting to fit 190 x 55 wide tires to 05 model R1 but heard that there may be issues over the width hitting off the frame and that you may have to adjust the chain, are there any views on this or any of you riding 55 tires with no adjustment. :rock :fork

190/55 should fit just fine just fine :-) 55 is the aspect ratio referring to the tire's height in percentage proportion to the width...Basically saying that the tire is 190mm wide and 55% of 190 is the sidewall height. Your stock tire is a 190/50, so the 190/55 is 5% taller. Basically to make sure you'll be okay, look at the area where the tire comes closest to the U of the swingarm...If you have 1/3" to 1/2" of space, you should have no problems.

55 is the height :secret:. It's a percentage of the width (190). As far as your question, sorry...I have no idea.

The 190/50 was one of the first things to go on my bike. As others have already mentioned, the 55 is not in reference to tire width.

Hi there thanks for some of the quotes i should have said the U of the swing arm my mistake some have said you need to go down the front sprocket which i do not want to do i as like the top speed that it has got again i know that 06 and onwards do not a have a problem as the swingarm was made longer in this model and that it might only be 04 and 05 that might have the problem many thanks :rock :sing:

The 16 tooth front may be a good mod anyway because of how steep first gear is. And with a 190/55 you'll be looking at a minor reduction of final drive. Wouldn't amount to more than a mph or two (plus these things are too dang fast to use top speed anyway). As far as fit, you should be good. Close, but it shouldn't rub.

Are you building a track bike?

I have had several friends run the 190/60. I even bought a scuffed set, but never got around to mounting them. I run 180/55 Dunlop D220 for street/hiway use, and I just burned up a set of Dunlop 208 GPa's with a 180/55 rear at the convention. Stuck like glue (except for once... my bad, not the tires). Like I said, if you run a 16 tooth sprocket, you will be fine with the 190/55.

here is a pic of my street bike with 190/55 btw you want to say 55 profile

here is a pic of my street bike with 190/55 btw you want to say 55 profile no im going 60 profile Dunlop 209GP 190/60/17 :thumbup i may have to add two lengths to the chain!!

no im going 60 profile Dunlop 209GP 190/60/17 i may have to add two lengths to the chain!! thats cool the ones i have are sportmax 209GP, the new tire they came out with. :thumbup

dont mean to jack the thread, but I have a similiar question. I would like to mount a 200/50/17 rear tire on my "stock" R1. its a 2004. Will I have issues with rubbing?

hi there again just to ask has anybody ever fitted a 190 x 55 to a r1 04 or 05 plate with changing sprockets or moving the chain

so will a 190/60 make the bike turn faster or slower on my 07 R1, which came stock with 190/50's

I remember when my friend tried to fit a 190/55 on an otherwise stock 05 R1, the tire rubbed the lower center of the swingarm...:dunno I just switched from a 190/55, but I have a 16 tooth front sprocket and it was still pretty close...

It will improve "turn in". Not necessarily faster but easier. Unless you are down a tooth on the front it is going to be a tight fit. Make sure you have enough room for the added height. Ride safe.

it will be fine i run a 190 55

55 is an excellent tire im runnin a 60 on my o6 r1

I am buying some 209 GP's 190/60/17's from a guy on craigslist as we email. They are the ones made in Britan, not US. So, I do hope they work. Otherwise, it will be a bit of a hassle. Have a track day on Monday at Thunderhill in Ca. I went from stock 190'/50's to 190/55's. And now this 3rd set will be 190/60. I am looking for a quicker turn in.

By increasing the rear tire aspect ratio, you are essentially raising the rear ride height, but there are other ways to achieve this as well. You could raise the rear ride height by altering the rear suspension (longer or shorter dogbones, not positive which on *your* bike). You can also increase turn-in by lowering the front of the bike in relation to the forks (move the top of the forks up relative to the triple clamps). There are some other options, but they are generally expensive (reducing rake by altering the upper triple clamp... for example). You should ensure that the suspension preloads are set correctly. A really good description of how to check and set the front and rear preloads are shown in Lee Parks book Total Control: High Performance Street Riding Techniques. It also goes into suspension adjustments and some other aspects of machine set up. You may be trying to solve a problem with tire aspect that could be resolved with a simple suspension adjustment. I'd also recommend Nick Ienatsch's book Sportbike Riding Techniques. Very helpful and easy to read.

more than anything, a 55 profile is supposed to be an advantage over a 50 profile due to the larger contact patch when leant over.

hi there all Just to let you know one of the best mods i have done is changing the rear tyre to a 55 profile instead of the 50 profile. 1. The first big change is the way the bike tips into each corner it is very light which may put you off the first time that you ride it as it seems very unsteady but if you jump on a 600cc bike then jump back on your own bike you will see this is ok this why i changed this as i felt the 600 changed direction much quicker than my own, i have changed the suspension many times to try and adjust to the same direction as the 600 steering, i am not a mechanic but i have learnt a few things about set up this does work very well. 2. The next change was to line it holds when you have tipped into the corner it seems to hold the line much better it also seems to change direction through mid corner if you have to pick the bike up then lay it back down or if you are going through a number of S bends left and right direction changes are a lot easier with no rear grip issues at all. 3. I have done a few miles on the bike so the chain has expanded so there are no issues on the part that it may hit your swing arm i have also done a lot of miles on the bike on the one day so if the tyres heat up the are no issues were the tyre expanded and hit the swing arm and i cannot say that if buy a new chain and sprocket that there might not be an issue if you are using OEM sizes i have been told that if go down 1 sprocket size there will not be an issue with this and just to let you know this problem is only with 2004 and 2005 models with the shorter swing arm the 2006 model has a longer swing arm so you could put on bigger tyres the OEM set up. I have noticed that i have a much better feel of what the front end is doing and inturn i have more confidence in the front and have went in much faster than i have before, i have been riding a bike since i was 8 years old, as i do not think that i am some kind of greart racer i do think i am quite a confident rider. The only extra i have on is a akrapovic y piece so it has nothing to do with any extras fitted except for the 55 profile. I hope this helps anybody thinking about this change as i had thought about this for a long time, yes it will feel totally different from what you have been used to that is why you will love it. Cheers and happy riding. :fork :fingr:

190/55 shouldnt be a problem. that size should have came stock...so much better in the turns. i believe the tire is 3/4 of an inch taller with the 55s vs 50s heres a pic that i found useful. http://i97.photobucket.com/albums/l211/brnrber/tiresize.jpg

First of all I know this is an old thread, but I have read this paragraph 2 times and I must be retarted cuz im not getting it.. CAN SOMEONE TELL ME FOR SURE if I have a 2004 model with everything STOCK as far as chain, sprockets... WILL I HAVE ANY PROBLEMS fitting a 190/55 in the rear? "rubbing whatever" thanks

"rubbing whatever" thanks No, you should not have any problem with the stock driveline. Dunlop lists the 190/50 as 24.81 inch diameter, and the 190/55 as a 25.38. There is a .57 inch difference in diameter, which would equate to a .285 change in height. Should be fine.

I ride 190/55's with no problem at all.

thanks folks!

No problem. Hope you will enjoy your change as much as I did.

thats what everyone say so im very excited, now just need to find a good deal on them and i'll place an order!

will a 200/55/17 or 200/50/17 fit on a stock 07 r1

i ride with a 200 rear metz. no problems

Wouldnt that be reducing trail? :corn Lowering the front will affect both rake and trail. But raising the back with a tire height increase will affect rake, but possibly not trail. Generally there will be about a 1mm reduction in trail for a 4 mm change in height. Make sense? :dunno

Lowering the front will affect both rake and trail. But raising the back with a tire height increase will affect rake, but possibly not trail. Generally there will be about a 1mm reduction in trail for a 4 mm change in height. Make sense? :dunno Thanks Dan, I got it. Wondering if the poster did :)

Thanks Dan, I got it. Wondering if the poster did :) No telling. It's one of those tricky areas like squat/anti-squat with suspensions that takes some looks. With a good ride height adjustable shock, I'd take the larger rear tire. But for the stock suspension, I would go 120/70 front 190/55 and keep the fork tubes flush, and maybe even a little less sag in the front, maintaining a good balance of damping between the front and rear; before I played with the geometry much. The R1 is an extremely well balanced chassis by design. We just have to get it there to appreciate it.

Am I going to have a problem with a 190/55 with a -1/+2 setup on an '07?

Am I going to have a problem with a 190/55 with a -1/+2 setup on an '07? nope

Am I going to have a problem with a 190/55 with a -1/+2 setup on an '07? You shouldn't have any issues with it from what I've read here on the subject.

55 is the height of the tire, not the width. You should have no problem with that tire, just get used to the way it turns it, you will feel like the bike is fallin in a turn, you will get used to it, then love it! :thumbup dont forget about the 100 mile break in period. then tell us about it.

Thanks for heads up. I knew about the width...just wanted to make sure that I would still have clearance. Once I'm done with the new 190/50 that I have on there right now, I'll be making the change.

Ive had my R1 for less than a year, I have a full connection with my bike, but the first time I had other than stock tires i put an old Dunlop 209 190/60/17 on her and i swear my first turn i went into I thought I was going to drop my bike, I ended up off the throttle and kicked my leg out supermoto style :lol, I was freakin schered!!! It took all but a few good turns to get used to. the 55 feels so awesome bro. like always have fun with it!

This I found a few years ago. Now is floating around here, and again. :)

And there you have it. Good find xdonniedarkox!

It would be cool to sticky the image somehow by a mod :yesnod

Hmmmm.... im about to get a new set of tires... maybe ill kick up to a 190/55 also.

Thanks for heads up. I knew about the width...just wanted to make sure that I would still have clearance. Once I'm done with the new 190/50 that I have on there right now, I'll be making the change. You won't have a problem. I'm running a 190/55 with -1/+2

Maaaaaannnn.... a 55 tire makes a HELL OF A DIFFERENCE!!!!!!

you will not have any problems, i run a stock 05 R1 with ccs and my bike was hard to turn in, once i put the taller 55 on the rear and a taller profile front the bike turns in alot quicker, it does make a lot of difference,and i havent had no rubbing any where from the tire, for the street i dont think it really matters if u use the 55 or not.

yup! i run a 190/55

I put a 190/55 on my 04 about 2 weeks ago. I didn't intend to switch from 50's, but I got such a great deal on some race takeoffs, I couldn't pass it up. I really like the handling and the way it falls into corners. I'm still getting used to it, but I think I'll have a hard time switching back to 50's after this. The only fitment issue for me was when I took my kid for a ride. My license plate is up under the the passenger foot pegs and the tire rubbed on the bottom of the plate with the extra weight. The tire is slightly closer to the hugger and the swingarm under the hugger. I can see where it might be too close if I had a new, tight chain and had to adjust the wheel a little forward.

hi there again just to ask has anybody ever fitted a 190 x 55 to a r1 04 or 05 plate with changing sprockets or moving the chain I have gone through several 190/55 tyers fitted to 04 R1.No mods.Bike turns nicer and holds a tighter line on corners.

Well, I have a few hundred miles on my first ever 190/55 and i do like it. The difference really is significant.

does tire design make any brand better, example pp's come with taller crown.

190/55 rock setup rocks. I run that on my 06. Zero modification, slapped right in. http://photos-f.ak.fbcdn.net/hphotos-ak-snc1/hs195.snc1/6569_96263068470_518403470_1930533_4567893_n.jpg

Ok here is a question that has not been asked. I just bought a Michilen power one 2ct 190/55. I have an 06 LE that has a ride height adjustment and the stock setting is the heighest setting. Since this tire increase the height, should I decrease the ride height to maintain the bikes stock geometery?

Since this tire increase the height, should I decrease the ride height to maintain the bikes stock geometery? If it's a bit twitchy and wanting to tuck, I'd lower it a couple mm (usually you get between 2 - 4 mm per turn of the ride height adjuster). Best to get a ride height measurement before and after adjusting to track what you've done. I don't think the ride height difference is that great, and I know of several that run the 190/55 tire with no real problem, but depending on what sag numbers you like there could be a difference.

I will take a few measurements before I throw the new tire on. I would hate to mess up my suspension when I paid to have it set-up last time I was at black hawk.

I will take a few measurements before I throw the new tire on. I would hate to mess up my suspension when I paid to have it set-up last time I was at black hawk. Honestly, if you changed tire type or size since the last suspension setting, you already have a reason to at least have it checked.

I put a 190/55 pp 2ct next to a 190/55 bt-16 and noticed the crown to be almost the same while at local dealership. So far best price I can find for 190/55 is with qualifier. maybe I will slap on 190/50 then next year go with the 190/55 assuming prices will be cheaper.

Well, I put the power one 2 CT's (55 rear) on tonight and went for a ride. The bike turns in way easier. My R1 is an 06 and it appears to have plenty of room between the swing arm and the tire. I just wonder how much the tire expands at 170 indicated or so on the front staight at Road America???

It should accommodate 190/55 with no problems. Tire expansion should not be a problem.

I have a 190/50 17 on the back, this will be the first time I put a tire on the back, can u go wider or is that it, and my wife rides with me 50 percent of the time and she isnt big at all, just wandering if u can or not, Thanks 07 R1

No.

I run a 190/55 size tire on my 2005 R1 - works great, no problems. I have Diablo Corsa III (dual compound in rear) tires on the bike. Switching from the stock 190/50 to the 190/55 size is one of the single best mods I have ever made on my bike (perhaps 2nd only to changing the front sprocket to 16 teeth in the front). After changing the tire, the turn in on the bike went from "okay" to fantastic. The 190/55 has more of a round profile, whereas the 190/55 tends to be a bit more like a drag tire (a bit more flat in the middle). The result is that - with the 190/55 - the bike leans over and turns in far more smoothly than before. When I first took the bike out after getting the new tires on, it was shocking what a change it made - it was almost like a whole new motorcycle. Aside from the change in handling, the bike does sit a touch higher in the rear - but not overly so. You'll notice there is a hair more lean when you put the kick stand down. The tire is a little larger and as a result it lends a little more confidence when cornering the bike. Probably also gives a touch more clearance on the rear pegs, but don't quote me on that (I run my Sato rear sets up pretty high as is :-) Anyway, I can't say enough good things about the 190/55 size tire on the R1 - if you have any question about whether you should run the 190/50 or 190/55, go with the 190/55 hands down. It makes the bike a joy to ride and there is really no downside. If you are worried about the height change on the bike (as far as touching the ground, etc.) don't. It's not enough of a change to notice or worry about. What the 190/55 brings in the way of benefits far out weigh any concerns one can think of due to the larger size. In a word, it's a great mod to the bike if your R1 came from the factory with a 190/50 size OEM tire. Ray

So i could put a 190/55 on the back of my 07 R1 with no problem ?:fact

So i could put a 190/55 on the back of my 07 R1 with no problem ?:fact You should be able to. You can on the 04-06 R1 no problem. The 09 comes stock with that size tire. I don't have any direct experience with the 07 model year, but I would imagine it's basically the same as the rest of the bikes. The 190/55 should work okay just like on the 05 year that I own. The 55 isn't that much different than the 50, just a bit taller and a slightly different profile. Ray

The difference is this: 190 refers to the width of the tread. 55 is the sidewall ratio ( Sidewall height is 55% of the tread width ) which would make the sidewall and therefore the tire taller than a tire with a 50% aspect ratio ( 190/50r17 ) which would only have a sidewall that was 5% shorter yeilding less ability to flex and apply the treadto the ground.

All excellent points. I also will only run 190/55 size tires on my bike. Another point for people to keep in mind is that the 190/50 OEM size tire tends to be a bit more like a drag bike tire - in other words, it tends to have a little more of a flat profile compared to the 190/55 which is more round. What struck me most between the two tire profiles is that with the 190/50 size, there is more of a noticeable transition when you corner - you can feel the bike roll off the flat part of the tire and onto the side of the tire. On my bike, this caused sort of a "folding" over feeling in the turn-in. I'm not sure of the technical term for this, but it just feels like too much turn-in from the bike when you corner (especially a slow corner, such as a 90 degree turn). Anyway, with the 190/55, because the profile of the tire is more round, you don't have as much of this transition occurring. The result is smoother cornering and more confidence in general on the bike. The 190/55 is also a slightly taller/larger tire, so you have a larger contact patch on the ground. I personally run the Diablo Corsa III tire, which is a dual compound in the rear. Anyway, one of the best modifications I have made to the bike. At first I wasn't sure about changing the size, but now I would never go back. Ray
