he won a lot which i would argue isnt the same as being faster. Mike had, essentially a factory honda cr85, while the team green bikes were a level below as far as equipment. Mike also was very strong at holeshots and in a 5 lap race, if you get a 10th place start, and the guy who gets out from puts down a lot of room in between that 5 laps just isnt going to allow you to catch up.
Now in a 30 min moto, when you have 12-15 laps....
Ryan also, in having to work harder to win, and work through the pack, developed skills that, when given more time to get up front he can cut through the pack and pass for the win. Go watch 2009 Glen Helen, it was what always happened in amatuers except they had 30 min instead of 5 laps. Mike holeshot, had a sizeable lead and villopoto caught him late in the race to pass for the win
