This website tells me all the things I need to know about dirt bikes from all its types of motors to why the dirt bike is shaped so strait and thin. this website is also super helpful with all the dirt bikes I need to study for this project it has a Honda XR 100 and it shows many different motors and there specifications all the way down from 1990.I think this website can help me see how big motors have changed since back then.This is why this website would be a great way to help me choose what I’m going to do for my project.
