I bet they do when they're taken care of and maintained properly, My old kx was pretty bagged out lol but yeah I had to be ready and have my weight in the right spot. At 6'1 and around 150 pds even now bikes ride like they don't even notice I'm on , My last street bike was a Suzuki SV1000S hehe 325km/hr and still had almost 5000 rpm left ;) (at 5am in the summer time on what felt like an abandoned highway... so as safe as possible) I'll own street bikes/dual sports and XC mountain bikes again but I'm done with the crazy stuff for sure (Not me but the MT I used to ride)
