Peak crank torque of the Zero DSR/X is 229 NM in the spec sheet, with a gear tooth ratio of 90/22 gives about, so 936Nm of torque. A 170/60-17 rear wheel is 0.3

Peak crank torque of the Zero DSR/X is 229 NM in the spec sheet, with a gear tooth ratio of 90/22 gives about, so 936Nm of torque. A 170/60-17 rear wheel is 0.318 meters radius, so 2943 Newtons of force where rubber meets the road trying to move 247kg of motorcycle. Acceleration is force divided by mass, so theoretical maximum the DSR/X can accelerate at 11.91 m/s^2, or 2.25 seconds 0 to 60. That's assuming absolutely no power losses, that it sustains peak torque throughout the entire run, that the rider has 0 kilograms of mass, and that there's no risk of a wheelie. I dunno, but I'd lean towards either BSing or hasn't actually taken a measurement with accurate equipment.
