I think any one who missed the days when they had the open class would want it back if they knew how awesome it was.Before Yamaha got the ball rolling to kill the big bike class,it was THE class to watch,the best of the best,the fastest of the fast.My friends dont have any interest in riding my 500 (the ones that admit it are scared of it),and the one guy that did compared it to "a Army tank with a rocket engine".I hate to see Kawasaki kill the last 500 prouduced,but to give them credit there the only manufacturer to keep the 500 around,and that says a lot about the original desighn!
