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.

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 . It's a percentage of the width (190).

As far as your question, sorry...I have no idea.

Assuming that everything in the driveline is stock, no adjustment is necessary. 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

I know for the 190/60 all my friends run a 16 tooth front. 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.

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.

Will I have issues with rubbing?

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...

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.
