click "enter", go to "Pimp My Ride" section, see post "New KLX250S".

Bonus is his pics of the KLX way in the air!

 

Sdunne is / was a member here a while back also. He ended up getting a YZ250F if I recall since he was into MX racing and the YZ is obviously more suited to the task though he did race with his KLX250S and gave it a good run. I think he placed just outside of the top 10 out of about 40 riders, I think - all with hopped up MX bikes so he faired OK. I watched one of his races where I met him and his wife and he definitely has some skills and was racing against some pretty good talent.
