Alright, here is the deal, I am doing a complete rebuild on a 2001 rm 250. Factory connection called w my suspension and said it's not off of an 01 rm 250.....but they were busy and haven't had time to figure out what bike the suspension actually belongs to. Today I started putting all new new bearing in the bike, as I was going thru putting new bearings in the linkage, all was going well until the beginning until I went to install the bearings in the swing arm where the linkage connects... Bearings are to small, spacer is to small.... Also leading me to believe the swing arm matches up to the mystery rear shock. Sooooo is there any way to tell if this is off a 2001 rm 250? Markings or anything? Need 2!!! !
