I just recieved notice that my factory warranty is going to expire. What's weird is the time period. I bought the bike on 11/28/08 and the expiration notice says its going to expire on 04/01/11. By my calculations thats about 28 months. I went through my original paperwork and cannot find the actual warranty, they must not have given it to me. Does anyone know what the length of the factory warranty is?
