found a 190/55 for 100 bucks brand new. but i spent the extra 40 and got a 180/55

 

i had Pirelli Diablo Supercorsas on my 600RR.They handle great but when they start to wear they go fast.I also had dunlop qualifier's and they where also pretty sticky but wore really fast and took forever to heat up riding in cooler temps.Pilot powers are great all around tires and not expensive IMO...but back to you ? yes it will fit but it seems a lil harder to get the bike to lean when going from 180 to a 190

 

Plenty of people race 190s on their 600s.
if you get 190 get a 190/50 this will make your bike drop into turns crazy...
