Well looking at the Bt 016's everything I have read says they are a wicked street tire. They make a 190/50 and 190/55 so thinking going with the 55 series. The B king comes with a 200/50 stock, its not a bad tire.
I ran a 180/55 for awhile on the Busa, liked the turn in but found the edge to easy. I also ran a 190/55 take off and loved the profile. So I am thinking going with the 55 series to get more sidewall contact, it is the size that gp bikes run. Now I am not riding like that, but its still a nice thought lol. So should I go with the 190/50 or 190/55 hmmmmmm there about the same price as well.
