Thought I would post a quick review of my updated suspension for people to look at. Bike is a 2010 YZ250, just had the suspension revalved by Factory Connection. I am an intermediate rider, race MX almost exclusively with a couple of mountain rides a year to mix it up. First off I will say that the stock suspension was never that bad for me (last bike was an 06 YZ250). But I did find that the back end kicked around more than I liked in braking bumps, and it did not track through the whoops as straight as I wanted, so I sent it off with my list of complaints and I will say that I am pretty happy with the results. It is not a WOW upgrade, but it is definitely noticable. The back end definitly calmed down, which I was happy with, and I could ride a little faster comfortably. They put a lighter high speed compression spring in, and I already had swapped to lighter pressure springs up front which happened to match what they recommended. Bottom line is the back end is quite a bit better, the front only marginally. One thing that suprised me was the sag. Their recommended sag was 108 in the back and sliding the forks up only 4mm in the front. I was very skeptical about this, but the bike seemed to turn just fine. Will I ever pay the $680 again? I don't know. It is kind of like any upgrade, sure it will make you a little faster but you will never be the fastest. As long as you are having fun, placing should be secondary in my opinion. I do know that this has allowed me to go that little bit faster, which hopefully doesn't translate into a little bit harder of a crash. I have only been to the track once too, so I will try and report again after a few races.
