They had heavy duty springs, exhausts, bar kits etc. You dont need all this massive suspension and big wheels to have a good 50.
But if a MSO kinda thing is what you want go out and get one, you will still have fun and thats the whole idea.
But im a Honda guy, i owned a China Back in 04 when they first came out. Sold it within a few months and got a Honda, I have owned a few now and i'd never ever ride anything else. They are just that good. Ive expeienced both and came out knowing what is the good choice for sure.!
