Braking:car vs bike

[Turbonetics]

which one has a shorter braking distance if travelling at the same speed?

i always thought bike have better braking ability due to its lighter weight.

but a bike mechanic told me car can stop better because it has 4 brakes,but iam not convince with this reason.

 

i believe this is going to be very subjective.

let's not compare Brembo,Spoon brake...etc.be more general.

i just want to hear your views.thanks.

Not only 4 brakes, 4 road contact as well

bike brake too hard can stoppie and flip over..

[Sickscientist]

I believe ur thoery is plausible as bike are very light compared to cars(lets say, 1.2ton)... That is the reason why cars have stronger brakes in front as weight shift occurs...

 

Thus, bikers have complete control of their brakes as they can control the frt and rear... So, my conclusion is, bkies have shorter brake distance...

 

Other views please..

not sure if you realise... bikes cannot do E brake at high speed. eg. 100km/hr.

 

The inertia will fling the rider out of the bike.

 

For car, we have seat belts.

Bikes have shorter braking distance I believe.

* Think I should rephrase this to I believe bikes can stop in a shorter distance than a car, but to achieve it will be dependent on the skill of the rider whereas in a car it's the tyres and brakes which matter more than the skill of the driver.

 

But bikes need skill to brake successfully with engine braking. As a pillion rider on my bro's bike, I noticed that no matter how short the distance to the red light or obstacle in front, he will always engine brake to stop. I think bikes cannot just brake hard at once. The bike might flip or pillion or rider might get jerked off.

 

 

For cars, no need much skill, just slam hard on the brakes it will stop.

i disagree, the brakes in the car (esp those with front/rear disc) determines the stop distance. and the driver only needs to worry about stepping on 1 brake pedal, and the brake system will take care of the rest (weight distribution, abs, ebd, whatever).

 

for bikers, all these 'automatic' systems are highly dependent on the rider. and humans may not react well during 'panic' situations.... ie. moderate strength on the frt/rear brakes to prevent flipping....

 

 

and also the fact that you have more surface contact area... I believe, all else being equal (speed, brakes, rider..etc), a bicycle will have a longer stopping distance as compared to a motorbike just on the basis of the tire size alone.

it is way easier to brake on a car. I've been riding for the past 4 years and just recently got a car. Basically for a manual bike, you can control both brakes individually. You can't brake equally hard for both, but rather use more of front brake than rear. The reason is the weight of the bike during braking will shift to the front, hence if u zam rear brake, sure lock the rear wheel up.. then u have to do abit of counterskidding. Not fun to counterskid from 100kmh to zero.

 

No you won't fly off ur bike, unless u let go, or u mean going from high speed to zero almost instantaneously.

 

All that being said, put a noob car driver n a rider side by side, the noob driver should have a higher chance of staying safe when braking

[Icekitten]

Maybe not rider, since he is holding onto the handlebars, but pillion will get flung off if just zam brake on a bike right?

[Slowmo]

just out of curiousity, how heavy is a typical bike? for eg a phantom ?

Yeah. Good way of summing it up.

 

I think it's quite difficult to compare braking distance because e-braking cannot be applied to bikes. It's so dependent on the rider's skill in braking. The less skilful and experienced the rider is, the likelihood that he will need a longer distance to brake successfully without incident is higher too.

yeap, riding is more focused on skill.

 

I remember when learning driving, the mantra for taking TP test is "Safety over Skill".

They don't need you to be super skilled and smooth, but you must be a safe driver.

 

But when learning bike, is really throw you into the deep end and must learn quickly, plus safety aspect also as important.

watch the fifth gear season 12 ep 3 got something on this topic

Lamborghini Gallardo Superleggera VS Ducati 1098 -

 

Model Lamborghini Gallardo Superleggera

Engine type 4961cc, V10

Power/Torque 522bhp @ 8000rpm / 376 lb ft @ 4250rpm

Transmission Six-speed e-gear

Fuel/CO2 13mpg (combined) / 400 g/km

Performance 0-62mph: 3.8sec / Top speed: 196mph

 

Manufacturer Ducati

Also called "Ten-ninety-eight"

Engine 1099 cc, L-twin,

Power 119.3 kw (160 hp) @ 9750 rpm

Torque 12.5 kgm (90.4 ft-lb) @ 8000 rpm

Transmission 6 speed

Top speed: 180mph

 

 

 

 

90mph to 0mph braking lambo wins by abt 5 to 6 yards

[Rhys11]

phantom's weight nt too sure, but a superfour, r1 and gsx are around 160+ to 180+kg, whereas most 2stroke 2b bikes like repsol or kawa should b in the range of 100 to 110

[Suhong]

Car got 4 brakes bike onli got 2 or 1

 

 

not sure anyway just kidding

[Rhys11]

bike 1 almost same like bicycle, individaul brakes for both front n rear wheel tat work seperately. so can vary the different braking force for different effects.

[Suhong]

i oso dun noe arh

 

i onli ride bicycle and onli noe that when i brake the whole real wheel would be lifted

 

[Rhys11]

cant recall too clearly, but hav tis impression frm readin in an article tat bikes can brake better due to its weight to tyre contact area proportion is smaller compared to cars, anyone heard tis theory b4?
