Everything is relative. 90% of bikes on the road will beat 90% of the cars. You can't really compare a stock Harley to a sports car.
I'm not talking about a "sports car". Newer V6 Accords and Altimas are running low 14s. Get a G37 sedan and thats pulling high 13s, stock numbers. My 2002 Sentra Spec-V 2.5L 4 cyl with just bolt ons was running 14.7s consistently. So no I don't believe 90% of bike can beat 90% of cars. 90% of 600 class sportbikes can for sure but even still I had a GS350 give me a hard time on 75 once.
