The SR/F by the American electric bike maker Zero is an all-electric motorcycle with stunning design and performance. The bike is unbelievably fast and its seamlessly powerful engine, with an array of performance enhancers, is a true delight treat for the rider. Adhering to its EV character, it does not require the recurring use of clutch and gear, plus its high capacity lithium-ion battery offers an extremely long range.
Zero Motorcycles have a reputation for crafting some of the finest bikes that are nature-friendly. With its new SR/F, Zero has once again matched up to its reputation, and here’s a glimpse at this great, green motorcycle.
A Stylish Road Presence
The new SR/F has adopted a sporty stance with a naked body design which leaves the powertrain largely exposed and visible from both sides. The bike is built around a trellis steel frame with a fully adjustable 43mm Showa SFF-BP. It has a 4.7-inch inverted fork at the front and a 5.5-inch fully adjustable Showa mono-shock at the rear. The bike rides on 17-inch Pirelli Diablo Rosso III tires, and the braking is powered by dual radial-mounted 4-piston J.Juan calipers and 320mm discs with Bosch ABS at the front and single-piston J.Juan calipers with 240mm disc.
The SR/F has a 57.1-inch wheelbase with a 485 lbs curb weight, whereas the premium trim of the bike has a 498 lbs curb weight. Being an EV, the SR/F is quite impressive in terms of carrying capacity. The standard version accounts for 515 lbs carrying capacity, whereas the premium variant can carry 13 lbs less. Behind the handlebars, the instrumentation is featured with a fully digital LCD screen that is also enabled for smartphone connectivity.
A Powerful Electric Drivetrain
The electric motor and battery pack of the SR/F are exclusively developed for a powerful, seamless performance. The motor is the Zeros’ ZF75-10 that delivers 110 HP and 140 lb-ft of torque. The electric motor is featured with an internal permanent magnet brushless architecture and a passive air cooling system to boost the motor's performance. This powerful motor can propel the bike to a top speed of 124 mph.
The SR/F Standard and Premium trims are available in variable charging capabilities. The Standard one is offered with a 3kW charger, while the Premium comes with a 6kW charger. The 3kW charges the battery to 100% in 4.5 hours, whereas the 6kW charger does the same in 2.5 hours. Zero is also offering a Rapid Charge System that allows configuring the bike for 3 kW, 6 kW, 9 kW, or 12 kW of charging at any standard Level 2 charge station. Plugged in with this system, the 3kW charger charges the battery for 38 miles within an hour. The same on 6kW will be 76 miles, and on 12kW will be 153 miles.
A Long-Range With Some Unbelievable Speed
The high capacity battery pack enables the rider to cruise for 199 miles which is impressive and sufficient for regular riding in and around the city bounds. The SR/F comes with four selectable riding modes - Eco, Sport, Rain, and Street. With each mode, the throttle response and power delivery reset to complement the ride mode. Apart from this, it has ten programmable custom riding modes that the rider can configure from the dash screen or the smartphone application.
The electric-powered SR/F is no less than any conventional gasoline-powered motorbike in terms of speed. The SR/F can do a 0 to 60 mph run in a tiny 3.7 seconds, and it is an enviable figure for many sports bikes in the category. Further, it can go 80 mph with an additional 1.7 seconds, and it can do a quarter-mile run in 11.83 seconds with a top speed of 124 mph.
A Completely Smart Motorcycle
Zero claims the new SR/F to be completely smart. The bike has an integrated operating system named Cypher III that acts as a hub to integrate all motorcycle systems that work in collaboration with the smartphone app. The Cypher is connected with the BOSCH Motorcycle Stability Control system (MSC), and this is the first time an electric motorcycle is featured with the MSC. This system allows dynamic acceleration and improved stability in various road surfaces and conditions, such as traction control, drag torque control, and cornering brake control. Further, the Cypher III is enabled with OTA updates.
The Cypher III’s operating system remains in synchronous with the mobile application through cloud computing. Riders can access information, such as the bike’s status and location, from the app. Particularly, the app monitors the bike’s condition and delivers four main types of status and alerts to the rider - charging, ride data, system upgrades, and updates.
The Zero SR/F is a step further for an electrified future with some super cool features. The Cypher III operating system with cloud-based smartphone integration is the latest feature. As per the company’s claims, no other electric or gasoline-powered bike at present has equipped the system, which certainly gives an edge to the SR/F.
