In the '70s, I was a teenager with a Kaw Mach 500, 3 cylinder 2 stoke with a hellashush power band at 6000 rpm. That was hell on wheels in those days as far as power goes. Had a factory tire that was 6 inches wide and flat thread patterned, just like a car tire. I can still remember on the tire sidewall a warning note about cornering speeds printed in the rubber. Great forward grip but would come out from under you in a corner on hot or wet pavement in a heart beat but wet grass,, don't even get me started. Car tires aren't made to lean in a corner and grip, made to stay vertical and sidewall flex while keeping the surf thread flat to the pavement. Heck of a highway tire but not for backroad twistes. Worked with a guy that put a car tire on a Ninja. Pulled out of the office and gassed on it will still leaning, just like he had done for a year. After several stitches and the cast came off his arm he put a bike tire back on.
