Wheelies and crash bars on a BB.....
Oh, the indignity...
Trail bikes for wheelies and crashing, BB for beauty and style....
PS no such thing as a crash bar for any of the BB models. The fairing takes the hit if you

k up or get torpedoed like Beestoys. The BB expects to be taken care of by whomever it accepts as a rider

.
Once you remove the fairing for a look see or some maintenance or cleaning you will see why.......
Here's some smutty pics of my semi naked BB that might help...... No handy frame or engine mounts though there could be potential for a high mounted crash bar that doubles as a half fairing stabiliser.....

....but there's not much for it to bolt onto behind the headlight.
