Car vs bike - cornering speeds

[stackmonkey]

After a 'discussion' last night with a friend, I need a definitive answer backed up with the physics.
I was maintaining that, for a given genre (commuter, sports etc) a car will always be able to corner at a higher G force and that the only reason a bike could go round any corner quicker was by more effectively straight-lining the road.
He reckons that the cornering lean on a bike and lack of weight will mean that a bike will corner quicker.
I still believe that for a given line on a corner, a car would be quicker, or that for a given speed, a car can take a tighter line.

This arose after the discussion on straight line speed. My 5.0 Chimaera vs his SuzukiSV 650? which we agreed would be close, but neither of us could call on.

On-road, you have too many variables in each corner to say that a car will always be faster, but on a track, car cornering speeds are higher due to larger contact area. Bikes accelerate faster, cars brake better and have higher cornering ability.

This is what I told him, but he won't accept it, which is why I need the physics behind it.

Sitting talking about G force and ultimate cornering speed is utter balls.....

No, we need this to eliminate all the stuff above about how good the riders/drivers are, and specific road conditions.
If necessary use the specific bike and car mentioned in my OP.

Tell if he was serious about being quick he wouldn't own an SV650.

It's his first bike after passing test on a 125, and all he can afford in addition to car, at the moment.

Anyone got any skidpad G's for bikes??

I guess this would offer a degree of explanation on mechanical grip.

Sport tire test „PS“ 5/2008
Bridgestone BT-016
lateral grip of 12.45m/s/s
longitudinal grip of 12.43m/s/s

both about 1.3G

Unsurprisingly 1.3g is good form for a sports car too. This argument is going no where!

if someone has similar figures for cars I'll be happy. I'd rather know the answer, and know I'm wrong, than not know the answer.
