i freakin hate 450r's soo much they are the most crappiest quad ever they look so gay and they aren't even close to the power of a yfz or a banshee...my freind has one and all he does and can do is wheelie....pretty gay
they don't have to be lined up but most people like them that way just turn them on the bolt patter thing then if they still wont line up then turn the hub on the axel
although the banshee is stock that is still gay i think they are a bunch off old guys who just want a comftorable quad they don't care about speed and hp
