I dont think i agree about this people dont ride for fun anymore :/
Obviously high level competition riders might get abit anoyed if they dont do something because its there life and carear, but that doesnt there not having fun riding.
i dont ride street much but on the street rides ive been on all people do is have fun !
and its pretty obvious why the bikes arent the same, if the bikes never got better then niether would the riding, If you like the old school style then its not like you cant buy bikes that are like they used to be, and if thats what you like then get one.
But for many people being on a bike like that and other people being on all the new better bikes being able to do bigger and better things would make it really not fun !
