This make 3 wins this season for Webb and Beta and several more podiums. Had he not been injured earlier, probably would have won the championship.
Other than Stillwell suspension, I bet the bike is close to stock.
I had an article that showed each bike and mods. Can't find it . Here's one. It breaks down his 350RR from 2010. Similar stuff on the 2 stroke.
