I remember a while back there was a politition who wanted to pass legislation to change the value of pi to 3.0 in order to simplify things.
I don't see a simple answer to the question like 1/10 sec per 100 lbs. The drag coefficient would have a significant effect on that ratio. Drag coeffecient is not static it changes with speed. Like the air feels thicker the faster you are traveling. So that's changing while your mass is not. You also have aerodynamics to factor in. Some body designs, and I would presume fairings, will greatly change the friction or required enertia by pulling the vehicle closer to the road. Which to the bearings and drive gear would appear to be increase in weight. (My porche would feel much tighter in handling at 100mph than at 35mph.) Of course it could have the opposite effect too depending on the body design.Because of this compairing a car to a motorcycle could only be done in a vacuum.
The ratio you're looking for can be generalized since we're only dealing with limited speeds and has nothing to do with top speed. But essentially it is a moving target.
I'd say that the faster you are traveling the smaller the ratio will be.
