The Tesla of two wheelers, Zero Motorcycles has just revealed SR/F, a naked electric motorcycle. With a max speed of 200 Km/h and a claimed range of 260 Kms on a single charge, this motorcycle sure makes some sense.
The SR/F delivers 190 Nm of torque and has 110 horsepower on tap. Just to compare, the Kawasaki ZX10R comes with 113.5 Nm of torque. So you can imagine how the SR/F would pull. Drag racers would definitely like to give it a try. SR/F gets Zero’s new ZF75-10 motor and ZF14.4 lithium-ion battery. The motorcycle uses an operating system called Cypher III, which acts as a hub to integrate all motorcycle systems.
The motorcycle comes equipped with ABS and Traction control; this is where BOSCH comes in to play. SR/F is the first motorcycle to integrate BOSCH motorcycle stability controller (BMSC) system which is renowned for dynamic acceleration and improved stability regardless of road surface or conditions. BMSC aids in straight-line ABS and cornering brake control, traction control and drag torque control. You get ride modes like Street, Eco, Sports, Rain and 10 more programmable custom modes. The motor is wrapped nicely in a steel-trellis frame and on rear you get a custom swing arm. The front end gets an advance upside down SHOWA suspension. You get a smart full-color 5” TFT LCD display as dash. You can view info like Ride modes, Navigation, Cruise Control, heated grip control and much more. The motorcycle can be connected to an app which transmits information like current bike status & alerts, charging, ride data, system upgrade & updates. You also get details on app like location, speed, lean angle, power, torque, SoC, energy used/regenerated.
