Hey guys just got back from my first singles track ride. What an intense and heart pumping way of riding! I ride snowmobiles A LOT in the winter, and powder riding all day including getting stuck for half of it doesn't relate to the work out I got just by spending a couple of hours at this singles track. Either way, for my first time, the 'ol KDX held up just fine against all the WR's. Even the guys that have rode for years I wasn't much further behind than 4-5 bike lengths. I felt pretty good with throwing it around. Except now I need a new front brake lever:) Sand...you know how that goes haha.
