Im looking at getting an 89 zx10 with only 10000 miles freshly restored, i wasnt going to get a 1000 but i want something big enough to stunt and not hurt the engine. I just sold my 09 gs500f i put 2000 miles on over 2 month and had a 2 stroke honda cr85 dirt bike before this and was just getting good at the balance point before that. Question is, am i crazy for wanting a bike this big? I feel like i could handle going slow in the streets but i dont want to kill myself before i turn 20
