I agree the 200's are overkill. From my experience a 190/60 is the optimal tire, super tall sidewall and plenty of width. The 200's add complication related to wheel size and fitment, which doesn't make anyone faster. Over the last few years, superbike racers the world over have switched to 190's and gone quicker, not slower... so there's something to be said about that profile.In all honesty, I think the 200 is purley for looks (a fat rear) and the benifits of a 190 are only obtained at the pointy end of the track day junkie / racer spectrum.
I'm getting new tires installed even though the original tires have only 1700 miles on them and appear to be "good".....because it's a 2005, so we know that they are at least 10 years old......they warned me that an old brittle tire could bite you in the ass. so to speak.When I bought mine the previous owner had put a 180 on the bike. I went with a stock 190-50-17 and like it better. Bike feels more stable. That's just me
