Say's that when they test and link the bikes up to a computer that measures rpm's and then ask the riders how much of the time they were wide open they say everywhere and computer essentially say's NEVER.
Not that they weren't going fast but wide open....not so much.
Mathes will tell you.
And I really enjoyed the Dubach podcast. Dr. D seems like a cool dude.

You would have to go to the desert or a grand prix course to collect 'wide open' telemetry for dirt bikes.
And Dr. D is like a human dyno- dude has more seat time than almost anybody, and can test better than any computer!
Now a good Pro rider.......sheeeesh...fergit about it! especially those lites riders! They are on full throttle more than they are not.
Doug is a stud and a legend.....but I don't care what that friggin' computer thing said.
Being wide open....and going full speed are two completely separate things here.

Wide open doesn't always mean popping off the rev limiter for any decent rider. Sounds to me like if you really wanted to know how often someone was wide open you'd have to have your computer linked to something else. Like the throttle.
What i was trying to say is....full throttle happens all the time.......full speed.....I would think very , very rarely. AND....is that full speed in top gear or in 2nd?
Us MX guys don't hardly ever ( maybe never ) get one of these bikes going full speed on any big outdoor MX track....let alone an SX track. GNCC and worcs riders will tell you differently though.
Measuring RPM's on a dirt bike tells you nothing about full throttle! Now if they were to measure how much fuel is shooting through the EFI and what the max amount is.....that will give you a better idea.
It's physics........to get to full speed.......you need full throttle , to get to full speed right? We are all on our way to full speed before we have to shut it down to make a corner , or not over jump something.
Understand what I'm saying?
What the Dr. was saying was the dyno and wide open don't really matter so much when building a pipe, a tranny or whatever.
It's usability. If you are hitting the stop all the time you need bottom end.
If you are hitting the stop rarely, you got the grunt and may need more top end so as to not need to shift. Because shifting up to get more top speed and then having to immediatly click down to enter a tight turn is not optimum on tight tracks, sx tracks.
So he tests bikes for this and makes his pipes according to those real world needs........and he says dyno #'s are for marketing programs not motocross tracks.
Jus' sayin'
Shake and bake!!!

If someone could pass on my thanks to Doug for that little gem. Gave me many a holeshot in 125's. Cheers
I'm betting all you guys that say you spend so much time with your throttle pinned, would be really suprised if you had a computer telling how much time you actully spend there.
