The bumps and holes that the tire molds into effectively increases surface area for that attraction to take place, as well as direction of force.

There have been several car vs bike races on various motoring TV shows. With enough money the car always wins. For 2x the price of a bike (say CBR1000RR, 1098R etc.) you could not build a faster car.

Even some of the fastest track-only cars run motorcycle engines.

Two class leaders; Guess who wins?

UUUUUUUUUmmmmmmmmmmm
So this time I read all the replies B4 posting.
Many references to cornering and acceleration but not one post about stopping.
Have any of the posters actualy been to a race track ?? !!
One post correctly said look at the stop watch. If the car has a lower number on the clock, then it is faster.
Now if you must do the math you can consider power to weight ratio, stopping power to weight ratio and corning forces.

And, it is not cornering speed or angle, it is the whole thing, in and out.
Slowing down, going around and accelerating. You may be brilliant, and look pretty, going around the corner, but a guy that has a better breaking ability is going to be in front when you exit.

A propper race car is faster on most tracks. Some tracks favour some bikes.
But we are street legal.

yeah some of these guys have been on tracks. But I doubt someone who has better BREAKING ability is going to win anything but the most trophies in the tree of shame

Apparently you forgot to read the OP.

Have you ever been to the dragon?

Its not like any race track anywhere. The same rules don't apply. You aren't braking and accelerating like you are on a track. For about 95% of the road you are either in a turn or transitioning into the next turn. Horsepower and braking ability come into play very little. Handling, as in, flickability and cornerspeed , are far bigger factors when you're talking aboot The Dragon.

thers no place a bike can get to top speed let alone a car

the only place a bike beats a car is pulling from a stop and pulling from curves, and thats what deals gap is

Your logic makes absolutely no sense at all. You're saying a bike is faster in the corners because it's faster in the straights?! Since a bike is faster than a car in the straights, it requires straights to gain ground on the bike, not the other way around! If it has almost no room to accelerate, then it's lost that advantage. Think about the argument you're trying to make for a second here...

just a fyi, the "unoficial" record at deals gap by locals is on a 1st gen SV. I managed to get that much but times and when it took place are still hard to get. I did get that it was not a stock suspension setup. So that answers the original question I posted.

Adhesion on the molecular level, as I said, is tiny. Take a nice, wide dragster slick and the average pavement, either asphalt or cement. Arrange the pavement as a wall. Put the tire in contact with the wall and measure the force required to start it rolling. Now start the tire rolling when it isn't in contact with the wall. The force required is exactly the same as is needed to start the tire rolling when it isn't in contact with the wall. There is no doubt that there is some molecular adhesion there, it's just so small as to be unmeasurable. Multiplying the surface area still results in zero measurable force. 1,000 times close to nothing is still pretty much close to nothing.

Compared to the traction provided by interaction between the various surface irregularities it's pretty much nothing at all.

Well, a friend who goes to Deals Gap often told me that the fastest run (unofficial, of course) was in an RX-7. He got to take a ride with the dude (and he's one of the quickest guys I've ridden with). I think it was described as ACT; A$$ Clinching Terror.
