The stock 2008 MTX front end has a number of issues. From personal experience and what I have read here it just doesn't work for trail riding and in spite of what Yamaha wants to admit to it isn't even set up very well for boondocking. The problems I believe stem from a high center of gravity, skis designed for powder not trails, shocks with poor rebound dampening and a front end geometry that is too aggressive for most riders. Here's what I have done.. Changed to woody's dual carbides, changed the upper and lower a arms to timbersled bark busters, and changed to fox float 2 air shocks, 1 inch shorter than stock. (In site of what Hrt Offroad claims) The bark busters and dual carbides got rid of most of the darting on hard packed trails. The fox floats are adjustable and have much better rebound dampening to take care of the sudden tendency to want to roll over in corners and in deep powder. The high center of gravity you will have to get used to. It requires a more aggessive riding style than any sit down sled I've ever ridden. I've got almost 1,000 miles on mine and am just getting used to how to ride the thing and I think I've finally got it figured out. I'll never go back to a sit down sled. Oh, and by the way I've already relplaced the subframe once. I haven't started working on the rear end yet, but the stock track need to be replaced and it bottoms way too easy on big bumps. It probably needs a different shock. On the other hand the engine is absolutely amazing.
