I finally picked up my first KDX and am really looking forward to it. It is pretty clean, seems to be mostly stock and well maintained with a few aftermarket parts sprinkled in.
It does show some signs of a previous more serious rider. The rear spring is blue, which I take to mean Race Tech. The airbox cover is long gone. It has an FMF pipe (though I am not sure which one) and pro-taper trials bars. The seller even included a new FMF muffler, pads, sprockets and chain.
After a quick look-over last night, I plan to change the air filter, install new chain & sprockets, install pads, buy some spare plugs, change the oil and loosen up the preload before my maiden ride on some tight single track. I expect to lower it, but will only start planning mods AFTER I have some seat time on it.
As an aside, I have owned many bikes, but only a handful of two-strokes. I am really looking forward to something that fits me and my riding well as I have gone through a number of bikes to single track that just didn't cut it. I especially like that this KDX costs 1/4 of the new Beta X-trainer, that I was also considering.
Will be interesting to see how this stacks up to the Freeride 350 I owned while overseas.
