A rather neat and long video of bopping around the boonies on a Kawasaki KLX150.  Sometimes smaller and slower is better on single-track.  Especially if you aren't a skinny 20 year old and need to get up and go to work the next day. 

 

 

Looks like a fun rally.

Cool video. The KLX150 is a great choice for off-roading in Thailand, it's an absolute bargain and under certain conditions it could match or even out perform a lot of the larger offerings.
