I believe it is around 15. And that would jive with what it feels like it would do compared to other bikes i've had who's 1/4 mile times i was aware of thru road tests. They really aren't very quick for thier size compared to the bikes of the 70's. A honda 450 was a bit quicker at about 14.5 if memory serves. Then again they weren't subject to the stiff emissions and noise regs we now have. I would kill for a speedmaster that would break 13 seconds. Say high 12's.
