The 2014 Zero SR ZF11.4 represents a massive milestone for high-performance electric motorcycles, looking sharp and stealthy in its factory all-black finish. As the performance-tuned sibling to the standard S model, the SR features a high-output 660-amp motor controller that unleashes instant acceleration without a clutch or gear shifter. The minimalist naked streetfighter styling highlights its twin-spar aluminum frame, a comfortable 31.8-inch seat height, fully adjustable Showa suspension, and a clean digital dash that allows riders to swap between Eco, Sport, and Custom riding profiles on the fly.
Powering this silent streetfighter is the highly efficient Z-Force® 75-7R brushless motor paired with a 11.4 kWh lithium-ion power pack. This combination belts out a staggering 67 horsepower and 106 Nm (78 ft-lbs) of immediate torque, vaulting the bike from 0 to 60 mph in just 3.3 seconds with a top speed of 102 mph. The ZF11.4 battery delivers a city range of up to 137 miles (or 70 miles at sustained highway speeds), utilizing a regenerative braking system to channel energy back into the power pack every time the rider rolls off the throttle.
