i have a 08 r1, bought it used and came with a 180/55 rear... if i get a 190/55 would i need to change the front also? im looking into getting pilot power 3. im assuming i would have to adjust my suspension too? any advice would be highly appreciated. chain is 520 i believe, whatever stock length is and still have stock sprockets

I have fitted and chewed out enough 190 - 55 tyres on my 98 R1 to have done 160,000ks on it with no problems, BUT, there is little clearance between the original sized chain fitted, AND, I always keep my chain adjusted correctly. This is because if it is allowed to get too slack, and if worn then sidways inertia will throw the chain to, and away from, the centre line of the path that it is suposed to travel between the sprockets.
Wheel misalignment is also an issue with the chain path, also. I ALWAYS string line the rear wheels!
Tire pressures play a vital role in tire wear, I weigh 105kilos, and run 35lbs front 38 rear, in the wet and cold, bumping them up by 1lb in the dry. (Bridgestones)

Scanned through all the pages.

Saw where 2 people asked about 200/55 fitting stock swingarm with 17 wheel on the rear but no answers.

I want to run a 200/55/17 Michelin Power Supersport on my bike. Will this be fine?

Also, anybody have experience with this tire?

the 180 tire isn't correct for an R1 wheel. You should be running 190....no you don't need to change the front wheel...you may need to adjust sag some (front and back) as the ride height in the rear will change.

When reading tyre sizes, you need to remember that the numbers mean -
17inch - wheel outer bead, or tyre inner diameter.
200 (mm) is the width.
60 or 55 or whatever it is, is the tyre height, as a percentage of the width of the tyre (aspect ratio).
So that not only does the change in aspect ratio affect the handling feel (side to side), it changes the gearing, and the amount of rubber in contact relative to the angle that the bike is tipped over!
On the rear, if you are an extreem leaner, then a taller aspect ratio helps over at extreem angles, because it will not try to hold the bike up, when well over and wanting to tip it further!
On the front, a lower aspect ratio speeds up steering, as it changes the line taken into the corner by steepening the steering angle, as it drops the front end, slightly, and it also changes the point of contact as the lean progresses.Taller tyres on the front will tend to scrub when subjected to acceleration into, and out of corners, as the drive pushes them wide. This scrubbing is more pronounced on longer wheelbase bikes.
Jacking, or dropping the suspension can help you get the correct settings to suit your style!
I have a perchant for earlier R1's, as I love the short wheelbase, and I have found that fitting a 190 section tyre on those models leaves little clearance for the chain, but just enough, if you run the standard 530 width 'O' ring chain and sprockets, given that my 98 R1 came from the factory with a 180 wide rear tyre.

I still have my 98 model R1 (160,000k's) which was from the second delivery of R1's sent here to Australia, is was delivered from the factory with a 180 section rear tyre as standard. I changed to to a 190 section and stayed with that. I wanted to try a 200 section when they came out, but was concerned about chain to tyre clearance.
I cannot vouch for the later model bikes, as although I have ridden them (all), and love the look of all of them, (apart from the flat plane crank models), there has always been an aspect about the early models that held my interest. Mainly, that being the longer stroke engine power delivery, and their simplicity of fewer electronics, and of having carburettors that can be tweeked at home.

Can anyone give me the actual Outside Diameter of a Dunlop Rosso Corsa 190/55-17?
I have two 06 R1s and was looking at putting these tires on both.
My standard R1 with stock gearing and an LE with a 53 rear tooth sprocket.
I want to make sure they will fit on both.

I think you mixed tire brands. Rosso is Pirelli... I run Dunlop, so no help from me, sorry...

You are correct. Don't know why I type Dunlop. Brain fart!
The standard R1 has Dunlops Sportmax and the LE has Pirelli Corsa tires. I love those Corsas. Very soft and they stick like glue at 32 psi.
The standard R1 has the original Dunlops on it and they are hard as rocks as they are now almost nine years old with only 3800 miles on them. I thought I'd try the Rosso or Rosso II tires on it but I see that they have a slightly wiered size fitment of 55 instead of the OEM 50 aspect ratio.
I just want to make sure they fit.

Yeah they will fit fine. I have 190/60x17's on my 04 (D211GPA Pro). It just means the tire is a bit taller in the sidewall area.

they'll fit. You might need to deflate the tire to put the chain on. I put a 190-60 ( basically the same as a 200 ) Dunlop GPA on my 01.
