Hello all! I'm just getting into motor bikes and I am interested in what size motor to get. 80cc must go faster then a 50cc, right? If that is true then what is the advantage of a 50cc? Also, I read the california laws forum and it seems like its not legal unless you have a motorcycle license, but others are saying that it doesnt matter. I live in south lake tahoe and I just wonder how all of the environmental people will handle a motorized bike. Any comments would be great. Thanks.
