Can a motorbike out brake a car?

[avgas]

hahaha oh man i missed alot in this thread.
Koba - your going down the right path. Its the feel that will tell you the answer.
Ixion is also correct, the machines of today are more complex are require complex math behind them (which is why i recommenced that some reading was required).
I recently read however that its not the fact that devices are more complex now - its just that they are visual more complex than previous attempts. Its an interesting argument when you think about it - an interesting example i found was when i was doing my pre-apprentice stuff for panelbeating. I made a sill for an Austin A35 panelvan. This was super complicated as it involved 2 cones meeting a cylinder. My classmates took 1/4 of the time to make a sill for a 1984 Corolla hatch.
Another example would be to map heat transfer in cast non-pure iron of the old days and compare it to the heat transfer of the new titanium. So have the designs become more complicated or the science behind them? An interesting argument.
But basically to cut the science out if is quite simple. Braking like all mechanical things relies on the man machine interface. Or how i like to put it - The moron that pushes the buttons. Not even ABS can save a moron.

at what point do you decide it is inevitable?

In that last 1 to 1.5 seconds.

Although it has never come to that for me, it is another skill for staying alive. Why should someone just sit there and go through the handlebars and A-pillars of a car? No thanks. But hey, you can if you want.

2 second gap, 4 in the wet.???

Hmm... I always wonder why we need to double the gap in the wet??
Surely the vehicle in front of you and behind you are also influenced by the the wet road and will take a longer time to come to a stop, so wont the gap between vehicles be unchanged??

Cos decelleration (braking) isn't linear. By the time you react you're doing 100 whilst the car in front is maybe doing 80. At this point you're maybe 1 second behind them. Try checking out the braking distance from 100 compared to 80 and then go figure.

On a typical bike with just a 2 second gap in the dry you're gonna end up hitting them....but at least you won't hit hem as hard as the @#$cktards who leave pretty much no gap.

It's well and truely obvious when shit looks inevitable. Most of the time you know as soon as the emergency appears wether you'll stop or not.

Umm....not always. I've managed to brake, slide and wiggle through gaps that I thought I had no chance of achieving on the many occasions some stupid dog/pedestrian/car/bus/lorry (I've hit all 5!) pulls out in front off me. Even when I've not managed to totally avoid, the bike's have ripped off bumpers and glanced off cars with much less severity than I would have had I just "given up".

Rubber on tyres ALWAYS slows you down quicker than your body sliding along the road........so as long as it's upright, STAY ON THE BIKE AS LONG AS POSSIBLE*. If the bike's going down then launch yourself away from the @#$cker.


*unless you're a silly bunny who's got no brakes and there's some nice kitty litter next to you.

Well good for you. However many motorcyclists do end up using their bodies to reshape cars. If they had presence of mind to stand up on their foot pegs in that last second before impact, then maybe they may have got away with only broken legs instead of much much more severe injuries or death.

A mate of mine once saw a guy on a Harley take off from a set of lights only to run smack into a red light runner. The rider stood up just at the last moment and did a complete somersault over the car and landed on his feet... then promptly walked over to the car driver and started punching him in the head through his open window. He said it was the most coolest thing he had ever seen!

hahaha yeah id have liked to see that! well maybe the second half! Good point about standing up i guess? i had never thought about that, gotta be scary though

Nowhere near as scary as the alternative though.

Watch what happens to a bike on impact. The rear end usually kicks up as the front plows in and the bike comes to a rapid stop. If you are standing up with your legs locked, (even if you are still hanging on to the handlebars leaning forward) then that energy will send you flying like an injection seat.

All you guys sound like a bunch of old women bikkering

another tip...unless yuou well schooled at slamming down the gears blipping the throttle etc and using the engine to brake aswell...just pull the clutch in at the start of the emergency braking!! saves you having to slow the inertia of the engine aswell...and theres a lot of weight spinning around in a small engine!

Disagree totally on this.

Well good for you.

No need to get sarky.

If you'd read my post and noticed the bit about

If the bike's going down then launch yourself away from the @#$cker.

then you'd see we're basically saying the same thing.

LOTS of accident happen because inexperienced motorcyclists "give up" on braking and/or cornering, panic and then do stupid things.

And a little voice in your head says "I don't want to be here !!!!"

This might answer some of the questions,but might change in the wet.

Hell I want one, the car that is.....

how could you ride on the road and watch cars pulling out and not try and think of somthign to do other then smack into them?
a) other side of the road
b) footpath
c)over the top + get insurance
