Shane Watts was the man back in the late 90's,early 00's in US off road.He started on a 125 and won,which had never been done before.People then said he could only win on a little bike so he then proceeded to work his way through the entire line up and I think won on them all except the 380 in one year-if I remember correctly anyway.
He was known for a few other things as well-starting races on tires that already had one race on them because he didn't see the need to change them,not running handguards ("you ride around the trees,right?")and trying to pick up every other racer's girlfriend/wife.I think he was in every pro riders head over here for a couple years.
The no handguard thing got him in the end as he got his left hand so smashed up surgery removed alot of the bones in it and effectively ended his career-at the top level anyway.
He currently runs an off road riding school.A couple of the local guys attended it last year in Maine and couldn't say enough about it.
A local off road bike club is currently in negotiations to bring him to New Brunswick or Nova Scotia this year and it appears it will likely happen.
Here's a vid one of the guys shot of one of his rut riding drills.They said it looks good here but before everyone got the hang of it,it was like a high-siding drill
