The California Superbike School is now on my bucket list. From the video, I'm convinced Keith Code's ideas are based in demonstrated fact and philosophical consistency.
Where I found myself disagreeing with ideas in the movie it was because of the street and track application. For instance, weighting the pegs on a heavy caliber superbike is a poor way to man the helm. On a 250 pound dirt bike it's a different deal. You can dominate the bike, standing on the pegs and shifting your weight to one or the other, but Code isn't teaching dirt technique on 250 pound bikes.
He talks about the faults of "crossed up" cornering, where the rider's body remains vertical. At parking lot speeds counterweighting, with the body remaining vertical, is of great help. Also, back on that 250 dirt bike I pine for, weight on the outside peg stabilizes the bike. It's safer and more effective to lean the bike under you and nobody drags their knees or hangs off to the inside on a supercross track. But he's not teaching parking lot maneuvers or dirt strategy.
I'd also point out a flaw in body-vertical turning I've never heard mentioned. I got back into street riding after a hiatus with a Sportster in need of serious nurturing. That was back in, lemme see, 1988 or so. The bike wasn't that old (an '84) but I'm convinced it started life as a factory lemon and suffered further abuse from an owner without a clue. It needed much laying on of hands.
My last experiences had been on dirt, and I found the Sportster really loose, to use a polite term, in corners. Then I discovered if I leaned with the bike it latched up.
Camber thrust is the turning force from leaning a crowned tire, and I believe that by artificially increasing the lean I was turning on too much camber thrust for the radius of the turn. The tire had to squirm instead of just roll.
Or I could be yet another idiot with a crazy opinion, that wouldn't surprise me, but I am pretty sure the techniques in Keith Code's film are spot-on and based on disciplined thinking.
And those techniques will save your butt. I can't wait to get into one of those courses. Fun stuff.
