I have ran cars on my bike and bikes with my car....
it all depends on the car and bike and the rider/driver
I ran a gsxr 600 with a little work done with my Cobra on a 125 shot and I only beat him by 2 cars.... in the same respect I ran a 03 R1 and he didnt go anywhere but he managed to pull about a bike length....
I ran CBRTRX's Z06 with my 05 ZX10 the night I tboned the car and my clutch was shot he didnt really go anywhere the first time but the 2nd time my clutch didnt hold for shit and I had to get out of it....
bottom line.... it will take an assload of horsepower to outrun the new litre bikes if they are well ridden....
