I wring my klr's necks pretty much all the time, it's fun to try and ride a slow motorcycle fast. I have a 2nd gen with the 685 kit a pipe and jetting, if it makes 5 more horsepower I would be shocked, but it does rev smoother. The basic motor design was conceived in the early 1980's and on paper it should do better, but it doesnt. I ride as fast as I can on the street and I'm pretty slow off pavement. I think of it like a kit bike, I have done so much to mine that it seems it's more me than Kawasaki, motor aside. I can see thinning the heard, ive got like 5, but only one road worthy, but I can't see completely getting out of KLR's all together. It is often my go to bike and I currently have a Moto Guzzi Stelvio NTX and a second gen Yamaha FZ-1, the Guzzi is no powerhouse, its way faster than the klr of course and will roll at 100 mph all day long, but the FZ-1 makes 140 hp and its not heavy and its serious fast. Ive has a 1700 vmax and they make 185 hp stock, that thing was 33% again as big as a normal motorcycle and it behaved so well, looked and sounded so good and it was really fast too. I also had a 2005 Triumph Rocket 3 with a turbo that made 230 hp and 230 ft pounds of torque, and that thing was a ravening beast, it revved like a 2 stroke, and would power wheelie at 100 mph, which was terrifying. They were neat bikes but they aren't in my garage anymore, but there's that dusty old klr that I ride more often than not, with no plans to sell it. Im trying to get my ass down to Argentina and ride back, time, business, wife, blah blah blah, but if I make it it will almost certainly be on a klr.
