Can a Motorcycle Brake Faster Than a Car?
bicycles reviews | bicycles videos | bicycles online
Can a motorcycle stop quicker than a car? A bike is much lighter than a car, so it should stop faster, right? On the other hand, cars have four brakes, four tires (and four contact patches on the road) so perhaps they can brake faster? See the full article at http://wp.me/p4ozly-j5 In this video we put that question to the test. Using an average car (a Holden/Chevrolet Cruze) and an average bike (Kawasaki ER6-n) we see which stops quicker. One test is stopping from a normal freeway speed of 100 kph (62 mph) and another at a suburban speed of 60 kph (37 mph). Both vehicle have ABS brakes but no other stopping aids. Both have near new disc brakes and tires. The idea behind this video is to see whether a car or a motorcycle would stop faster in an emergency situation - with driver and rider reacting as normal.

WHY DID NOT YOU DO THIS TEST İN CURVES ? WHY THE CAR LOW LEVEL AND THE BIKE TOP LEVEL? ..

this is the 1st time i seen this test done with the motorcycle winning. I've seen it done on Car and Driver and Cycle World and the car wins hands down each time. Speaking from having a Hayabusa and a Corvette to high oerformance vehicles, the vette out stops my busa 10 times out of 10 times. i dont know what they were doing in this video. surely theu weren't hitting the brakes hard in the car like you were trying to avoid a collision. if you dont here the tires beginning to slightly squelch from trying to stay planted against the pavement then youre not using the brakes to their maximum stopping power. cheap car vs cheap bike car wins. average car vs average bike, car wins. high performance sports car vs high performance sports bike, car still wins.

This isn't a test between a superbike and an average car, nor is it an average bike vs a sports car. It is a test between an average bike and an average car. And the bike should always win, if you can't stop when a mom-mobile slams on the brakes in front of you, you are traveling too close, period. This video is actually part of a article, and this is where the sport car comes in. When a sports car slams on the brakes, it'll do so faster (shorter distance) than a motorcycle. Which means if you're following a sports car, increase your following distance. Just like the mom-mobile should while following a bike or a sports car. They're basically saying that there isn't a straight car vs bike break distance answer that applies to all cases. Instead, sometimes the bike will easily stop shorter and sometimes the car will. And if either is following too closely, then they''ll rear-end someone.

wide sticky tires and oversized brakes... car corners and stops faster hands down every time... better check the mirrors before you slam the brakes though
-
This is not an accurate, representative measure, because we witnessed a sports bike with with premium sports brakes riding on soft compound tires against a cheap run-of-the-mill car with even cheaper economy tires.
Most sports car (measured by Motor Trend's Ignition show right here on YouTube), brake in 100 ft form 60 MPH. -
what were they using for speed. the speedometer? bikes are usually generous
-
Thank you for this comparison. Been curious for a long time on the braking distance of a motorcycle. Its more important than any other aspect of a bike and yet nobody covers it. so thanks again.
-
Doesn't it depends on which car/bike it is?
-
wtf... the bike started slowing down before the car and was behind the car before it started braking... then it locks up its wheels.

"most" vehicles are made to brake as fast as they accelerate or better. this will give you an idea of various vehicles capabilities whether it be a motorcycle or car. faster the vehicle accelerates, the better the braking... now there is variations in weight of all and particularly seating position for motorcycles with a clear advantage to sports/tourers vs cruisers or scooters... a car with 4 occupants differs just as a bike with a pillion passenger. likewise a modified engine vehicle without brake modifications... in reality, if conditions are fair and road surface reasonable, the average motorcycle will generally outbrake the average car everytime... it's when there is rain, road paint, rough roads/gravel, or corners that it gets interesting and 4 wheels can be better than 2 under brakes... it's 60% the quality of rubber on the vehicle, 20% the operators capabilities, and 20% the vehicle itself... add ABS and the vehicle is around 30%, person 10%, but rubber, at around double the importance of ABS, is still 60% of the equation and of max importance. crap rubber means increased distances in every vehicle so buy the best you can afford.

+TheRideAdvice was the intention of this video purely to prove that a bike can stop faster than a car or was this intended to show that bikes generally stop faster than cars?

This is pseudo-science. It takes one data point (the delta between this bike and this particular car) and presumes (without even an attempt at justification) that the result applies to any bike and any car. The entire notion that it depends on vehicle type is an open question to begin with. The appropriate null hypothesis is no difference, not "which one", and the "test" should average multiple results and statistically infer a difference at a given probability level (a difference that is not explained by unknown/random factors like measurement error). Then (and only then) if one has shown a probable difference one can estimate the effect size for the chosen probability level. This requires multiple measurements, probably dozens and careful control of other factors that might influence braking distance. Braking distance depends on at least the following obvious factors: A) the ability of your pad/rotor/caliper combination to generate friction (up to the point where the wheels lock and then it stops mattering). B) The tire to weight ratio, C) the friction coefficient for the combination of the tire rubber and the road surface , D) the conditions on the road surface (wet, dry, hot, cold, sand?) E) the quality and trade-offs used in the ABS algorithm, and probably most importantly DRIVER SKILL. If those things are demonstrated to be equal then you might begin to expose any effect related to the vehicle type. If they can't be demonstrated to be equal then one must transform the data by careful multiple regression of measurement of all factors in order to subtract the observed effects of those factors (and yes I am aware that sometimes multiple regression is not the right statistical tool). To do this you would need dozens of samples at each of a variety of configurations and conditions with a variety of drivers. This video proves nothing that can be extrapolated beyond the individual vehicles shown in those exact configurations in that exact weather with those exact drivers...

Again, fairly slick production, not too hot on content.
but it proves that A bike can outbrake A car LOL
Now what happens if you take the top 100 of each? -
Right, compare a good bike with a fat, slow, hatefull cheap car! Do the test again vs a >2004 BMW/MERC/AUDI/AlfaRomeo, VW, etc.

Be aware of your reaction time also, you will smash on the car that is in front of you just because it applied brakes and you were not prepared / too close. if you can stop quicker does not mean you can tailgate. You require more or less 0.62 seconds to react, so 20 meters at 100kmph

40 years bikes dirt, road and track. Do own spanner work. Have 6 different bikes with 1 1000 cc sport bike. Assess this for what it is. Perhaps some commentators could include a test with the many environmental variables alluded to; corners, wet roads or rider only and without ABS. Leave out any emotive ideas on bike riders. I've always thought I could rein my road bikes in to a stop quicker than my car. All out - front wheel just off lock up and compressed under me and back wheel chirping (some race riders hardly use rear for braking). No ABS. A locked wheel must be unlocked and braking drill repeated (set up and progressively harder as bike weight moves to front and loads the front compressing tire into a larger contact patch) As the riders here know, can't just grab with the right hand or it will lock and front lock up will have you on the deck very rapidly. In isolation, this is an interesting exercise.

At 2:01 I could see the licence plate . 274 TPK

This video is a joke.... Cars will ALWAYS out brake motorcycles. What fucking world are the people who made this video living in?
