Stopping distance Bike Vs Car

Americans think that a bike can stop quicker than a car. According to
me the bike will take longer to stop under all conditions, and the car
will be close to the shortest stopping distance of a bike all the time
because you just press the pedal instead of all the other factors
arider has to think about and finesse.

There are a few magazine reports that say the bike stops quicker but
has anyone seen any real test of this?

This came up because they think drivers should watch out for
Motorcyclists because they can stop so quickly the driver will be
caught unawares.

 

**** off, you thick ****.

In general, less mass = easier to stop.

However:
A super duper oil tanker (ship) can stop quicker than a Harley.

I'd rather emergency stop in my nice ABS car than on my 600 bandit. I can
stop pretty quickly with both, but I've done a number of emergency stops and
I don't like the way my legs feel after doing it on the bike.

I'd say my bike stops in a shorter distance, but only in a straight line.

I once saw a test on a very wet track where a F1 car with slicks stopped
quicker than a normal car with wet tyres on. Totally irrelevant I know.

 

If the car has perfect brakes and sticky tyres it will stop better
than a bike, as the bike will stoppie first. On the other hand,
a Vauxhall with OEM tyres has no perceptible braking effect at all.

 

Total bollocks.


Standard bike with quality brakes and tyres will stop quicker than a
standard car with quality brakes and tyres.

 

Excuse my ignorance.
"legs feel"?

 

Nice 'facts' there. Care to point us to the (reliable) source?

Or are you making it all up as you go along?

I know which one my money is on.

Never watched a speed hill climb where there are cars and bikes at the
same event have you?

As in "I don't like my legs feeling the way they feel after quite a scary
incident".

I don't often do emergency stops on the bike for fun, although I do
occasionally test my ability when it's safe to do so. Do it all the time in
the car though, but that's just my driving style.

 

Depends on the bike: depends on the car. Surely you have the brainpower
to work this out for yourself?

That's septics for you. Sounds like some **** tailgated someone and his
lawyer is loking for an excuse.

 

Sorry, I didn't know I was writing for morons.
If you have sticky enough rubber and brakey enough brakes,
the hardest you can brake is when the back wheel(s) leave the ground.
This happens first on a bike as the line between the CoG and the front
wheel's contact patch is steeper on a bike than a car.
There are other effects - wind resistance helps the bike a little and
wings on F1 cars help a lot.
In practice most sportsbikes have adequate tyres and brakes; most cars,
especially Vauxhalls, don't.

 

So much for Newton's law in all that...

 

In my motorcycle training course this summer, after we had all practiced
emergency stops from 50kph, the instructor did the same in his car, and
stopped in about 2/3 of the distance the best had managed on bikes. The car
was a Mercedes SLK, though.

 

Which of Newton's laws were you considering?
If you have a criticism, let's hear it.

To elaborate, if at the point of stoppying, the line from the CoG
to the contact patch is at angle x from the vertical, your rate
of deceleration is tan(x)g. In most cars, the coefficient of friction
of tyres on roads is exceeded long before that, but there are a few
amusing videos of micro-vans tipping over forwards.

 

Total bollocks.

 

The one about mass. This will have greater
influence on the stopping distance than worrying
about the CoG.

 

And the bikers were, presumably, all novices. Proves nothing.

What impresses me, now that I've got a bike with ABS[1], is just how
hard one can brake in wet conditions. I haven't cut the ABS in yet.

[1] I presume it's working.

 

TOG@toil, ,

Don't worry, you'll find out.

The Thundercat rig at the Silverstone CSS was a revelation for me -
outriggers so you can't fall over, overinflated, nearly down to the canvas
front, a rainy day and you had to deliberately lock up the front to try to
learn how to recover if you do lock it up.

I didn't the first couple of goes because I just wasn't pulling on the lever
hard enough. I stopped pretty fucking quickly, but it didn't lock up. You
needed to be really ham fisted and unsympathtic to get the wheel to stop
turning from 20-30mph.
