With a motorcycle and a car with equal weight to power ratios, which one
 

is faster through a curve?

motorcycle of course, less weight and better handling : - D

Depends who riding/driving. In general, the motorcycle should be faster. It can lean into the curve more that a four-wheeler and therefor take the curve faster.

Probably the motorcycle but that would depend on the person manning the vehicles... a newbie motorcycle rider might have a "fear factor"... lol... then again how is the car set up to bank the corners??? OH SO MUCH TO THINK ABOUT - difficult questionHotttttt Doggggggg

Equal weight and power ratios??????where can you find a car like that????It all depends on a lot of things other weight and power....try suspension set up !, chassis , what type of curve....is it banked, flat,up hill down hill a lot of factors go in to place I WOULD HAVE TO PUT MY MONEY ON THE BIKE ! ! ! !

The car of course. It has much better traction on the curve. This has been proven time and time again on top gear. I'm sure there is a vid on youtube of it. Even if the bike has the advantage, a car can take the corners faster. If they have equal power to weight (and Im not sure in what universe that could happen, maybe its an ariel atom?) the car would smoke the bike always.
