To the guy who was wondering if i knew anything about motorcycles, yes i know a bit being a dirtbiker, and cyclist myself.
what exactly do you want to know? most is the same, you have the engine, works around the same principle, just setup a little different, a smaller gear box, a frame, wheels brakes, and sometimes a few luxuries in between.
if you are interested in more about motorcycles then type "~motorcycle" in your post somewhere...now i have to ask, what do you want me to go over next? (ask any questions at any time, also)
-drivetrain (where the power goes after the engine produces it ect.)
-wheels, tires, and geometry around that in general
-how your engine powers your heat, ac, sunroof, radio, recharges your battery ect.
Il take any other suggestions you want!
EDIT: MAKE A VOTE IN MY POLL TO THE RIGHT!
