That's about 1/100 of the full story in the development of that bike not to mention they had to remove an engine bolt on the SP2 chassis to help get more flex into the chassis, but I see that little tidbit of info is not mentioned anywhere
I read a somewhat similar interview a few years ago with Edwards chief mechanic, and it was the SP1 bike where the removed the upper rear engine mount bolt to induce frame flex.
They also made some cuts in the swingarm to make it flex more under throttle to keep the tire from spinning up all the time. Essentially the SP1 was too stiff.
All these improvements were engineered into the SP2.
The SP1 and early SP2 were down on top end compared to the Ducatis, but during the Suzuka 8 hour race, they made some changes which added top end, which Edwards used to advantage in the later half of 2002.
I wonder what all they changed? We'll probably never know.
Was watching the video of the 2002 Imola race and noticed that Edwards never exceeded 11K on the tach.
This was different than Ducati, which I heard was revving theirs to 12.5 to 12K. It also trashed their engines after each event as well.
