Followed from a suggestion on one of Kevs uTube links was this

A car v bike test by Autosport.

I always thought that, on average, whatever speed advantage a bike would have down the straights would be matched by the car on the brakes and in the corners. Giving a sort of similar lap time. Although I did despair a little at the offering with knackered tyres, I mean why bother?

Depends if you consider the car and bike spec to a fair comparison. Obviously nothing is going to live with an f1 car, but then is it fair to compare a car with massive aero performance to a bike that has none whatsoever? I think not.

Take the aero out of the equation and things are more clear.

Anyway, I guess the argument will rumble on according to preference.

Just for clarity, bangs for buck. The bike wins every time.

Re the fair comparison....

My opinion is compare the fastest bike with the fastest car. F1 wins every time.

And then there's the question of cost...


Plus the bike wins in a straight line.

I've always worked on the basis that I can't fall off a car

  yes, that's what I meant, I've more chance of falling off any bike than of falling off a fast car...

So on that basis, for me at least, a car will always be faster

That's who's been waking me up  Just over the fence that race track

Given the poor design of the human body and its lack of ability to withstand impacts much above 10mph without significant damage, surely the item with a protective shell demonstrates a true engineering evolution where as the alternative two wheel setup shows nothing more than a poor lazy engineering approach.

[Marks DTM Calib]

but then is it fair to compare a car with massive aero performance to a bike that has none whatsoever? I think not.

Of course it is, one approach compromises on weight in order to utilise the advantages of aerodynamics, the other compromises on aero to take advantage of weight gains.

If taking the same arguement you could state 'is it fair to compare a bike with massive weight advantages against a car which has none whatsoever? I think not'

Engineering is about trade offs to find sweet spots in design

.....and a variation of the car/bike theme.

There was a time that I thought that nothing would beat the outright brutal torque of a big bike but cars have come a long way recently. Cars can now put the power down from a standing start, something that they couldn't do a few years back.
Track comparisons are never going to be fair because what do you calculate? Horsepower to horsepower I'd imagine the bike will always win, power to weight ratio is debatable due to the cornering skills required to get anywhere near a car in tight bends, so what are they proving?
It takes a car with serious hp to beat a big bike on straight line runs, so again no comparison.

All I know is, you have to be into bikes to appreciate the thrill of riding them.

Take your point about cost but would a bike be faster in a straight line than an F1 car? 

In this short vid...

...you can see the bike off the line gets the better start. if they came out of the corner at exactly the same point (which i think the just about do) on to the straight (i.e. both with momentum) then I'm not sure

[Webby the Bear]

....and I didn't even mention the ABSOLUTE demolition of the bike around the track as a whole
