I went for about a 30 mile ride today through some seriously rough crap. Rocks, mud, deep mud, sand, water, roots, swamp and everything else I could find. I frickin' love my KDX. I was riding with 3 others who were on ATV's and they just could not keep up. The only time I had any problems was when we got into some serious bog territory. I don't mean the generic term "bog." I'm talking at least a half-mile of floating bog. You could have one foot on semi-solid weeds, and the other would be over the riding boot. That's the only time I got stuck...really stuck. Took about an hour to make it through that one. All of the ATV's got stuck too so I didn't feel like an idiot. The rest of the time, it was me riding "casually" for about ten minutes, then I'd stop and wait for five minutes for the wheelers to catch up. I figured it would save gas that way. Better than idling behind the ATV's.
Today, the KDX took whatever I threw at her and came back for more. What a bike!
