I live near Portland, Oregon and my rider is a '76 KZ900 I bought new. I'm also in the process of restoring another one and a '73 Z1.

I prefer to use the front and slowly add rear as the frame settles a bit from the front application. But in this case, I'd probably opt for the shoulder.
On a different subject, I'm not convinced motorcycles necessarily stop faster than cars, though I see that written as fact quite often. That's a broad statement covering a lot of cases that would differ. (I would not be surprised if a new minivan stops faster than a stock Kz.)

I do agree that at least most modern cars can stop in a shorter distance than a KZ. However, the car in the video didn't appear to be doing anything close to a panic stop. The bike, on the other hand, had a pretty long distance between it and the car when the car initially slowed down, so it should have been able to avoid hitting the car. As you pointed out the bike rider hit the rear brake hard, and assuming that little dip of the front of the bike was caused by him applying the front brake he used the front brake far too late.
It sounds like you and I use the brakes very much the same way - use the front and slowly add rear as the frame settles a bit from the front application. If the guy in the video ever decides to ride again he should first get some instruction on braking and on how to avoid target fixation. Ed

Then I see the front end take a little dip, at which point the rear locks up, without any change in foot application. In my opinion, the mistake was applying a large amount of rear brake first, then hitting the front. Hitting the front shifted just enough weight forward to lock the rear.

Absolutely see and agree with where you are coming from. All things being equal then yes a bike should stop faster due to less weight and less mass to slow down, its simple physics. However the real world is messy and nothing is ever "equal" so that laboratory setting just flat out never happens. We are also taking about 40+ years of technology change between brand new modern cars and these old "high performance" bikes (at the time they were cutting edge and high performance, but by current standards it is archaic and grossly outdated) and there is just no way that even an economy modern car would take longer to brake with modern rubber, braking materials, ABS and all of that to be shown up by a 40 year old bike.
Im not hating on vintage bikes, quite the opposite as I absolutely love these bikes, but I am a realist and live in this world and know the limitations of what this technology is and can accomplish.versus brand new tech. Maybe I am being too critical and too cynical, but I would rather stack the deck in my favor and err on the side of caution and underestimate what the brakes can do versus what I hope they can do.
Just my two cents, I'm sure I am far more cynical than most though... :laugh:

I agree. The braking ability of the bike was not an issue in this crash. It was definitely one or more of inexperience and panic and fixation.
I just found it interesting when I searched the stopping distances of common some cars and motorcycles. The range of stopping distances overlap quite a bit, and the car/van/(and maybe even some pickups) stop sooner than some modern bikes (including sporty bikes). I just don't think a generalized statement can or should be made about stopping ability. Yes, bikes are lighter, but their contact patches are much smaller. Nowadays, ABS plays a huge role in the final stopping distance, apparently, such it may be the final determining factor.

Yes it's easy to comment on this video especially from behind a keyboard safe at home without knowing the conditions a lot of things could of happened. But the important question should be what this guy chooses to do to prevent this from happening again. If he practice riding without brakes and on different vehicles off the public road that can't make his road riding any worse .
