200/55/17 to 190/55/17

It should be fine. Based on my previous experience of changing 190s down to 180s I would say it will actually be an improvement in handling giving a faster turn in. Did it on my 998s and my zx7r.

 

what size rim is on the 1199?

 

and how wide is the rear. 5.5, 6 or 6.5?

 

I'm surprised it's not 6

 

190 fine

 

The traction control might need resetting as you will have changed the circumference of the rear wheel.

I know it does affect the Aprilia RSV4's but i seem to think they may automatically recalibrate by themselves after a while. Don't quote me on that though.

 

Wouldnt it affect the ride height by a nano-fractional-millimetre? (55% of 200 is more than 55% of 190) Not that you would notice, but the TC is probably ser for 200...

 

I feel it would make it more sensitive or less sensiteive. Adjust the settings to suit...................

 

I think that one size drop is a sound move Rockmeister going by earlier models (some might say N/A). Handling etc aside, you could look at a tyre manufacturers bible* for actual physical differences between the two but you can come up with a figure that's close enough using the theoretical dimensions provided :- Height will drop close to 5.5 mm and rolling radius will be just over 98% of previous (200/55/17).
* I have a Michelin one somewhere if necessary.

 

It works fine. I have a customer who's changed it and already put good miles on the setup. It may need one click down on the traction, but as with everything it's a personal thing. Try it and if you find it's cutting in too much then make the adjustment. The "55" profile is a % of the tyre width, so as well as a slight decrease in width, the sidewall height is affected slightly and this change in circumference is the thing that is picked up by the DTC. Bear in mind that the designated sizings are "nominal". Different brands, or even tyre types, differ quite a bit although being the "same" width/profile.
Just for the record, the Panigale runs a 6" rear rim. The manual is incorrect :wink:

 

This is similar to the conversation I had with a few people when searching for a new tyre for the Desmo which was listed as a 200 section.

Here is the list of the tyre sizes etc at that time. These were all listed as the actual measured widths for a 120/70/17 and 190/55/17 on a 6" rim:

[TABLE="class: tborder vbseo_like_postbit, width: 100%, align: center"]
[TR]
[TD="class: alt1, bgcolor: #F5F5F5"]Make/Model/Front size/Rear size/Front weight/Rear Weight

Bridgestone BT 003 RS, 120/189mm, 4,2/6,6kg
Continental Attack street, 117/185mm, 4,3/6,6kg
Metzeler Racetec K3, 115/191mm, 4,1/6,4kg
Michelin Power one, 118/197mm, 4,1/5,9kg
Pirellin Diablo supercorsa SP, 118/197mm, 4,2/6,1kg
Dunlop GP Racer D211, 119/196mm, 4,6/7,0kg (in this case rear is labeled as 200/55/17)

[/TD]

[/TABLE]

As you can see the Dunlop D211 labelled as a 200 section tyre is no wider at 196mm than the Michelin Power One listed as a 190 section. Likewise, 195/65/17 Dunlop NTec slicks are far narrower than the GP Racer which are measured at 196mm.

So I think that the traction control system is going to have a hard time differentiating that easily between all these. It will work all the same with them all, but not as perfectly as with the OEM tyre. But it will still work. Mine got confused when I switched the stock tyres for the Dunlops, but you only get an odd amber light.
