It's not stated in the curriculum so no, I wouldn't go there with noobs. If more advanced students wanted to discuss it because they had heard it elsewhere, then I would still probably only discuss it with them and not with the entire class.

And the problem is? (The reason is they need to learn where it is, and they don't have to let go of anything to do it.)

They're teaching friggin' beginners, dude. It might not be important to you, me, or anyone else reading this, but it sure makes the n00bs feel better. Don't believe me, come on over, I'll put a new rider on a bike that's too tall and I'll let you help them pick it up the first dozen times.
IIRC BRC curriculum does NOT require you should be able to flat-foot the training bike, but it sure is a good idea when teaching someone who hasn't ridden before and you'd be pretty stupid to deliberately put someone onto a bike where they couldn't reach the ground. Your typical overweight middle-aged female has more than enough trouble with a 250 rebel. I can't imagine putting them on a tall bike. That said, I have had some good students who were sufficiently "altitude challenged" to have to tip-toe a nighthawk but wanted to ride a "proper bike" instead of a cruiser style. They are usually NOT the ones that have trouble anyway.

You appear to suffer under the common delusion that the BRC was ever meant to be the end-all be-all of motorcycle safety. It's not- it's supposed to be just enough knowledge and skill to get out and learn more on their own. This is why I when it's compared to other places.

Mmm. Loved my engineering dynamics text book back when I was working on my mechanical engineering degree. Showed absolutely positively why and how a wheelie on a motorcycle is a physical impossibility. I found it laughable, the rest of the class took it as gospel.

Teaching students to delay using 70-80% of their braking, in the name of safety, is appalling, imo.

And for the record the claim wasn't applying the rear brake lowers the tail. The claim is that applying the rear brake first reduces the nose diving you get when applying the front brake. A claim I do not agree with. Simplly put, X amount of braking force on the front wheel imparts Y amount of force along the coil springs of the fork tubes, which results in Z amount of compression of those springs. Regardless of the rear braking activity. Physics 101.

Applying the rear slightly before the front helps settle the bike and prevent some of the dive towards the front. It works, try it.... at least on all bikes I've ridden. One potential variable is they were all chain drive so I can't speak on shaft or belt drive. Another is that I've never had linked brakes or abs - YMMV.

The detail I think you're missing is that the front does not work completely separate from the rear. One part of the system affects how the rest of the system responds.

Other than that, its interesting how your class says you can't wheelie a motorcycle and that's bs... but physics 101 says braking on front and rear are completely separate with no interaction and this is gospel.

Well, the Wolf seems to have the same black half helmet and Marlon Brando jacket as the "Sheep."

Ahem...

A Wolf in Sheep's clothing, perhaps?

Yep.

Damn, I didn't have my camera or cell phone but a guy and I rode a bit up Highway 143 East of Robbinsville,NC to drag a Harley back on the road with his Jeep. The bike was only down the side of the hill a little bit so it was a no big deal with little damage except a bent up crash bar,etc. The little pirate guy was shaken up but able to ride his Hog away.

Anyway, he said he must have hit a rock and had to lay er down.
No sign of any rocks, just a normal curve on a clean asphalt road.
