Hi I've has my 09 nytro MTX for only two months and have already bent the right font end and the tunnel jumping and playing around I didn't think i was that hard on it to warp the tunnel or pusht he right ski back and inch, I looked at my buddies new polaris dragon and his whole sled looks a lot stiffer and more built than my nytro. Anyways i see alot of pics of aftermarket tunnels and boards that look a lot stronger and stiffer than the stock ones can any give me some websites that have some good tunnels and boards. I thinks i'm going with the timbersled front end.
