ZEROSR ZF13.0 +POWER TANK 2017 - Present

　　The biggest improvement for this year lies in the drivetrain components. First off, the factory bumped up power output across the board with a maximum of 60 horsepower out of the “S” and 70 from the “SR.” Torque received a bump as well with a maximum of 81 pound-feet and 116 pound-feet, respectively. As always, that torque is available the instant you crack the electronic “throttle” without the need to first gather the rotational inertia in the engine. If you can’t imagine what that means, I assure you all ambiguities will be removed the instant you throw a leg over and grab a fistful.
