Interesting article re: 0-100-0

http://www.visordown.com/features/ze...ero/11616.html

The chart on the final page is telling. The goldwing beat a number of cars to 100mph, but it took nearly triple the time of any car to stop.

umm F1 Indy cars can do 0-100-0 in less than 5.

I'm a little confused. The fastest 100-0 time was 4.0 seconds by the Porsche GT3. The Goldwing did it in 7.0. That's not even double the time of the Porsche. How do you figure triple the time?

Because I looked over the article too quickly. It is still interesting, and illustrative of the surprising dynamics of motorcycles.

K. Thought I'd overlooked something. My brain isn't functioning well today, so it wouldn't surprise me.

It's definitely an interesting comparison. Seems like those that have the belief motorcycles can stop faster than a car are incorrect. I wonder how the numbers with bikes manufactured for the US market would compare, since they dumb ours down for lower power output. (Working under the assumption that the bikes in the test were Euro-market bikes since the author uses "tyres.")

shouldn't be any difference between us bikes and euro bikes. a goldwing is a wing no matter where it is. the only vaiables are rider, road surface and and weather

Never had a Euro-market bike to compare, but I've seen numerous claims that the power on US-market bikes is restricted to meet emissions requirements, and that Euro-market bikes don't have that problem. I know that my Sabre was underpowered from the factory. Honda sets their bikes to run lean to meet our emissions laws. Granted, it was the pilot screw set to run lean so it would meet emissions at idle, but when the pilot screws were set "properly" it made a big difference in off-idle response.

well, true that emission laws will dictate power delivery. but hard equipment like brakes and such are standard across the board. only foo-foo stuff like paint is the major difference

Absolutely correct. The stopping distances would be the same. Guess I should have been specific and said acceleration times.

gotcha. personally I could care less about the acceleration time of a wing. but stopping time is VERY important in a bike. I have to say I am shocked about the stopping ability of the wing.

Also I'd bet the writers have a fair amount of experience with brake modulation. It would be hard for a newer rider to equal those stopping distances.

Contact patch on front tire of bike...maybe a 120 width tire...compared to a minimum 185 mm width car tire with a profile designed for a much larger contact patch....to me it is surprising how well the bikes did, I guess weight really does make a huge difference.

Weight, tire width, and I think heat dissipation has a lot to do with it. The rotors on a car are bigger (thicker, anyway) than those on a bike, and the rotors on high performance cars dissipate heat very well. Bike rotors are thinner, so they heat up faster. Heat diminishes stopping power. The author even commented on the smell of burning brakes after his run on the Goldwing. Wouldn't be surprised if he glazed the pads.

yup, and dont forget the huge size difference in pad sizes. on some bikes you can fit all 6 individual pads into an area about the size of an index card...some cars each pad is almost that size alone, then multiply by 8.

the difference in contact area of pad to rotor is pretty drastic.
