190/55/17 vs 190/50/17

Hey guys

Question: Has any1 ever gone from a 55 to a 50 rear? If so, what are the pros & cons associated worth the change?

Reason Im asking, is that I got a killer deal on a 190/55/17 and wanted to pick ur brains if it would be a mistake? I do mostly twisties, sweeps etc on public mountain roads.

Thanks guys

Huh... you just contradicted yourself, I assume you mean 190/50/17  :027:

Anyway, if you're an average rider, and most people are despite what they say, then the rear might feel a little more planted on general cornering. However, if you are a serious rider then it will be a lot worse as you're pushing right up to the side wall. Turn in will also be slower. Never tried a 50 on a S1R but it could feel like a 55 thats done 2000 miles. Personally I wouldn't do it but it probably won't be the end of the world.

The warranty on the new tyres will also be null and void as you've fitted a non-standard size that differs to the manufacturers recomended size.

I've also got a Fireblade that has 190/50's and many people go the other way and swap to 190/55's, so...  :164:

Thanks for your advice.
On all the replies on this subject that Ive read, it is also more or less than what uve mentioned. I also had 50's on my 2008 Fireblade.
To give u an answer, I only do road riding and occasionally lean to meet the edge.
The tyres on special are Metzeler Sportec M3's.

On the subject, will any of the electronics like DTC or ABC be affected if the bike is fitted with 190/50/17?
Thanks :084:

I also wanted to get a 50% for my rear, but my dealer's service department said it will throw off the electronics control, and NOT to do this.

My dealer accidentally put a 50 series on my 1600 a couple of years ago.  I rode the bike over 1000 miles before discovering it.  No codes and the handling difference was pretty minimal, and I do ride the curves pretty hard. But its not something I would do on purpose. 

When I had my Concours 14 I went from a 50 to a 55. Im not going to say night and day difference, but it was noticeable in a good way

I had an issue with 190/50/17. My DTC was constantly being set off. When i switched back to 190/55/17, bike was perfect.

I do not recommend it.
