How exactly do they measure lean angle? I assumed it was based on the center-line of the bike but in their animation it looks way off... more like they're measuring the rider's angle. Is it just a bad demonstration or am I missing something?

Yep, looks way off. I use the accelerometer in my iPod 4th gen to calculate mine (using Harry's Lap Timer) but due to bad vibration and wheelies it can be off too. You could throw a gopro capture in gimp and use the angle calculator against the horizon i.e. approx 54 degrees:

Thanks man and nice pic! I had Harry's Lap Timer app at one point but never had a chance to use it. I've since switched over to an android phone.

Take a look at the point of contact on the tire with the pavement. It's at that point they are showing the angle from, where the actual contact patch is. If you move the right angle to the dead centre of the tire, it would line up with the centre of the bike as well... At least, that's what I'm seeing :P

The line should be parallel to the tire and it is not. It's clear to me that the bike itself is not at 64 degrees but the rider does seem to be. I agree the video is somewhat misleading.

Cool nonetheless.
