It's a few years old, but I'm still amazed ever time I see it. Make sure you watch the WHOLE thing. Makes motocross look wussy. I still don't understand why it isn't popular in the USA.
After every race season, I always consider selling the race bike and getting a SM. This year is no different. I actually have the race bike posted on a supermoto board looking to trade for a street legal or race prep'd bike. Racing is loosing it's appeal to me, not to metion the cost and the fact that I only did 2 race weekends this year. Sometime I even consider selling the race bike and picking up a few dirt bikes so the Wife, Son and I can head up to the U.P of Michigan and ride the logging and O.R.V roads. But a SM would be a blast to ride and race. Problem is there isn't that much racing here in Wisconsin that isn't a one day deal or done on a weekday.
I just purchased a Yamaha 2002 WR426 to make street legal and then to turn into a supermotard. Looking for a set of 17" wheels that I can switch back and forth, for when I want to ride dirt and then street. Bike is a hoot.
