I have a set of these on a 2015 BMW R1200R, it straddles the line between sport bike and big heavy touring bike at 500lbs wet. Before the GT's I had a set of standard road 5's and had zero complaints. They lasted 14k miles and had phenomenal grip wet or dry. Switching to GT's I've put about 500 miles on them so far. The big difference I can tell is the stability and nimbleness of the bike is markedly better. You can feel that the tires are stiffer because it changes direction much more easily than with standard 5's, yet at the same time bumps are actually noticeably smoother. In summation, if your bike is on the heavier side, these tires work exceptionally well. I can keep up with and often outrun my friends on sport bikes with much stickier tires. I expect these to last the same as standard 5's if not longer. Couldn't be happier with them.
