Colin Edwards talks about his favorite...

CE: The (Honda VTR1000R or RC51) SP-2, 2002. The 2000 bike, I mean, I won the championship, but it chattered its brains off. 2001, we got a bigger rear tire, front tire stayed the same, chattered even more. Every track we went to it chattered. And I’m sitting there looking at (Troy) Bayliss in front of me. Come out of the corner, I’d see that thing flex and just walk away from me. And I’d come in and I said, ‘Man, mine’s just going sideways. It’s like ice.’ And I said, ‘When I look at his bike I can see it. I mean I can see the bike flex. Mine’s not doing that.’ And about midway through 2001 they were already in the development stage. I went to the last race Sugo, I said, ‘Let’s test the ’02 model.’ And I got on that bike and it would do whatever you wanted to. You could just throw it in and grab a handful and everything worked and no chatter. Rear shock that worked good and we never changed. And all we did that whole year was click, click. We never changed fork springs, we never had to do any of that. I never had a year before and I never had a year since that I could do that. That bike was just magic.

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

Nice post, interesting to hear it from that perspective.

Duct tape can't fix stupid...but it sure helps muffle the sound

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.
