You could bend the pivot mount or maybe crack the lever and not be able to see it. Looking at mine there seems to be a place it could crack and you not see it. Hard to tell.

I would remove it and bend it and examine it closely before re-installing.
I’d examine the switch and linkage too as you never know when a big shock occurs.

Thanks, popgun. That's exactly what I was wondering about. I won't try to bend it back until I get home and can detach it.

As I’m approaching my freeway exit I get over with plenty of time and fall in line with other traffic slowing for the exit. We had collectively slowed to around 50mph when my bike went into a violent wobble that must have lasted 2 or 3 seconds. My feet were thrown of off the pegs and the rear started alternately beating the insides of my legs while the bars whipped back and forth. I thought for sure I was going down, but I kept my cool and reacted without panicking. My legs are killing me, but I kept the bike up.

Speeds were about 50mph and slowing gently, no hard braking, no known road obstacles. It felt like the rear brake was locked up for the whole wobble. Riding the last mile to work felt odd every time I applied the rear brake….once I parked the bike I found that the rear brake lever is bent up and out which drastically changed its position relative to my foot. That’s why things felt different.

Could that lever have been bent (out and up) by my leg smashing into the side of the bike? It wasn't like that when I left the house. Think I can just step on it to bend it back, or would I be putting weird stress on other components that I can’t see?

I'm still trying to replay the whole thing in my head in the hope that I can determine the cause of the wobble. The bike has never done that, and aside from cars ahead and behind me conditions were pretty favorable.

My CB1100 started to head shake when the tire wore like this, and I replaced it. I switched to a different brand (can't remember off the top of my head right now) but the head shake completely went away, and the new tire is wearing much better (I'm on the third front tire now). A friend of mine crashed his CB750 back in 1981 because of unexpected head shake. Luckily he survived, but he sold the bike immediately.
