I have used the search and I am tring to find one post with the information I wan't. About a year ago there was a post about improving the rear suspension on an 05 by using a RMZ450 rear shock. I just need to know what year modle was used. Got the bike down for some upgrades and I should have wrote down in my notes the comment about the rear shock mod. Can anyone help me find that needle in a hay stack post or may have the information I need. Don't say get another bike, got 5 bikes and my son and I love it. This is my son's #1 bike.
