High Performance Road Cars VS Bikes.

Braking test of current ( both ABS) regular commuter type vehicles, car vs bike.. &.. the bike wins..

OMG, now this is a regular commuter? Exactly the same bike with fairing

A bike with dual semi-floating 300 mm petal discs can´t be considered a regular commuter for a braking comparison, at least if you want to be somewhat realistic

Anycase, have you checked the full article linked on the video? Becasue looks like they had some sort of remorse and ended the article with this

an average bike has far higher performance characteristics than an average car. In general, an average sports bike will have higher quality brakes and better tires than an average hatchback or a family saloon [...] But as soon as you get a car that’s remotely sporty, say a Golf GTI, the car will begin to stop in shorter distance than a bike. Physics will win and with those four tires, the equation of a = μg will see the car pull up quicker.

Yeah, A-125.. that Kawasaki is just a tarted up commuter bike, it aint no supersport..
I'd never buy a road bike that didn't have twin discs on the front.

& I put up an actual test, not a guess about 'physics'..

What is interesting is how lame the brake test results gained by US testers of superbikes were,
( posted at the bottom of the 1st page) , so again, its about having the skill/confidence to brake hard
enough to really have the front tyre of a bike howling on the edge of lock up, juddering, hopping, squirming,
- & writhing the handlebars with the forces.. a lock-up is ok - too so long as you are in a straight line.

That graph got me confused... what´s the difference between british islands and british isles?

Its not a 'graph' (X/Y axis/numeric) as such, at all - A-125.., see : Euler diagram..
& it clearly presents the relevant discrete data sets - so such distinctions may be readily understood - with a mere glance..
.. so, most - would not be .. " ...me confused..." about the information graphically displayed..

This test of a road Kawasaki from 40+ years ago, using a single front disc ( two discs - was an optional extra, back then),
shows it still managed to stop from 60mph - in less distance than the bikes posted by Bdr... - on the 1st page..
111.7 ft..

If you restrict your definition of 'graph', as you do, you are , of course, correct. But there is a wider definition. See for example http://www.combinatorics.org/files/Surv ... phEJC.html.

I don't think for one moment Andrés didn't comprehend the Venn diagram. He was looking for, and received, a useful distinction between Isles and Islands as used in this context.

That´s it Henry

Yeah, A-125.. that Kawasaki is just a tarted up commuter bike, it aint no supersport..

So the categories are regular commuter, and then supersport.... no category in-between

Sorry but no, that Kawa is a sport bike, not a regular commuter. That article is comparing a sport bike with a commuter car.

They they say theirselves at the instant you compare with a sport car (not supersport either), the car wins. And that´s not due to some guess about physics as you say, physics are physics, they even put the ecuations involved

[NoDivergence]

A Z06 can stop from 60-0 mph in 94 feet.

yes, that has been mentioned quite a couple of pages back.

Henry, to be technical about it - its a Euler diagram (not Venn),
& the 'British Isles' set, all encompassing & able to be perceived at a glance..
..left A-125.. apparently "...confused.." & asking for ( needless, surely) further explanation..
There it is..

That Kawasaki is a commuter, it has an economy vertical twin cylinder engine,
& does not even have a USD suspension front end..
It carries an ER- designator, & E= economy, ZX- is the Kawasaki sporty bike designator.
It does stop - on test - from 100km/h in ~30 meters - which would equate to ~100 feet from 60 mph..

& FYI, A-125.. adjectives are not facts, & physics formulas remain academic theories - until demonstrated empirically..

[bdr529]

100 km/h ≈ 62 mph and 30 meters ≈ 98 feet

[J.A.W.]

Thanks Bdr..., so fairly close then.. & not too far from the trick Vette..

& for interest's sake here's an article about big fast Moto G.P. ~1.6G race bike braking..

Thanks. I stand corrected about the diagram type.

No, academic theories are things that have been demonstrated to be true.

Hypotheses are ideas that haven't yet been proved.

[J.A.W.]

The formula remains of academic/predictive interest only, such as in this instance, until validated/empirically verified..
..in this instance by field test/control of variables/repeatable-outcome within normative statistical gradient - results

Show me/prove it/bullshit or not? As is said in the real world..
