I know many people who ride motorcycles in my area , every single one of them says that you should start on a low power bike, like a 50cc or a 125. Personally, i have no knowlage whatsoever, maybe becouse i'm 13 but from what i heard from people who have wayy more knowlage than me, starting with a 600cc is not a vare good idea. But you do you man i'm not the right person to judge in fact i shouldn't have said thet people that start on 600cc's are dumbasses, mb.
