Zero has been proving that electric tech is a viable alternative to petrol-engined cars for nearly 15 years. Since their founding in 2006, Zero has been refining and updating their electric motorcycles, and the Zero SR/F embodies all of that experience. A naked standard bike, the SR/F has a range of between 160 and 200 miles, depending on options. Add to that 140 lb-ft of instant torque delivery, a top speed of 124 MPH, and charging times as low as 60 minutes, and you have a motorcycle that's ready to ride when you are — without any emissions. Zero sees the SR/F as its halo product, and the bike has features that make it stand out from the rest of Zero's lineup. Cypher III, Zero's smartphone app, tells you everything you need to know about your SR/F, from charging status to warnings if someone is tampering with it. It also allows you to customize the SR/F's digital dash, along with ride-sharing features and over-the-air updates. With the SR/F, electric motorcycles have truly arrived.
