Tyre

Not really the case compared to a 180/55. The 190/60 is 10mm wider for only an extra 5mm of height compared to the 180/55, so minimal difference.  Compared to a 190/50 deffo better turn in. 

But also factor in that a 190 carries a weight penalty so increased gyroscopics and unsprung weight, both of which have a negative effect on handling.  

I think most tyre preference is in the head especially for a road rider on a 120 ish bhp bike but if it makes you ride more confidently then I guess it’s worth it. 

Food for thought but a 190/60 supercorsa weighs about 6.35kg and a 180/55 about 5.23kg. The weight difference is not far off the difference between standard Rsv wheels and oz forged wheels. 

Yes, but i am not sure how accurate your source is(not that i have one that i am sure they have the correct numbers).

It is interesting for me too to know the tyre weights, but i googled the EAN number from your screenshot and i let me to bg.mynetmoto.com
There the numbers look reasonable at first glance, but not when you try to compare the supercorsas

Here they state

5.8kg for 180/55 SP V3 Supercorsa

which does not see to be right.

Well for people that may not  know Micah , he's one of the best engineers in the business.

Him and twi others made a Rotax twin do over 200 mph ,Team Punisher.

And Spoonz is right about the height difference,I use a 200 in mine , 2005 Factory and i would not go back to a 190 but mine is a gen 2 and can take  .

Depends what you want to o with the bike ,with  my Maxton shock  it turns quick , probably too much for people.and all the people that say the 180 is better,i say it is personal choice,on the Aprilia trackday i went under them 180s  .

But the bike was much higher as was my R1 after fitting 200 tyres .

I would use 200s all day long  , and I was told it would not handle ,but not a problem.I believe the bike tipping in quick is down to suspension setup than the tyre size . If you leave the suspension alone and don't adjust it for the tyre then maybe.

I had the R1 set up at MCT and it has all Ohlins suspension, when Darren set it up ,he asked me what tyre size I will using ,200 slicks 60 threaded 55 or 60.

Anyway it had 190 s in it ,when I brought it back I took it for a ride with the 190s and I had to pull it into corners ,phoned Darren at MCT and he said phone after you put the 200 s in ,I did and it turned so quickly it took me by surprise,that's why i say it is down to geometry and setup of the suspension,Also there was a lad on here who was using 200 slicks and had no problems.i will be using 200/60 SC2 in about a month in Spain ,I hope I can get my feet on the ground �£👍
