2019 Zero SR/F Preview
Zero Motorcycles has officially unveiled its all-new 2019 Zero SR/F. Dubbed a streetfighter by the Santa Cruz-based electric-motorcycle manufacturer, the naked e-moto represents a massive step forward for the electric motorcycle manufacturer. The SR/F boasts more power, shorter charging times, and arrives with a complete rider aid package.
Also, Zero has imbued its new electric machine with “smart” technology thanks to their new Cypher III operating system.
Zero’s new offering puts it in a similar performance electric bike category as the recently announced Lightning Motorcycles Strike, and the Energica Eva, Evo, and Esse Esse 9, as well as the highly anticipated Harley-Davidson Livewire.
We can’t wait to see what this new bike is all about in person, but until then, here are the Fast Facts.
1. The brand new air-cooled ZF75-10 electric motor produces a claimed 110 horsepower and 140 ft/lbs. of torque. Yes, 140 ft/lbs. A commendable 110 horsepower @ 5000 rpm is nothing to sneeze at on most sporting motorcycles, but the absolutely staggering 140 ft/lbs. has us curious about a great many things – most of which involve wheelies. Also, the top speed has increased to 124 mph.
2. Claimed range should be more than enough for your average commuter. Zero has stated that the SR/F has an effective range of 109 miles at 70 mph in mixed environments (city and highway). City mileage is rated at 161, while 82 miles can be achieved on the highway at 70 mph. However, with the addition of the Power Tank, effective range can be increased to a claimed 200 miles.
3. Charging times for the 14.4 kWh Z-Force Li-Ion battery pack has been dramatically reduced thanks to integrated Level 2 capabilities. It is also enhanced with accessory charging units. The standard SR/F features a 3kW, which has dropped charge times to 100% from 9 hours to 4.5 hours when making use of 220v Level 2 charging stations. The SR/F Premium boasts a more substantial 6kW charger upgrade, which will complete a 0-100% charge in 2.5 hours at Level 2 stations. An additional 6kW Charge Tank can be added to either model, set to become available later this year, will decrease charging times even more. In the case of the SR/F Premium, the accessory 6kW Charge Tank will result in 12 kW capacity, reaching 95% charge in an hour.
4. A new trellis frame works in harmony with a concentric swingarm, dubbed the “Power Pivot” by Zero. Marking a step forward in design aesthetics for Zero, the trellis frame is put on full display, but that isn’t the most interesting part of the puzzle. The new “Power Pivot” swingarm makes use of a concentric design, allowing the belt-drive’s tension to remain the same as the swingarm moves through the suspension stroke.
5. Batteries still carry the bulk of the weight, and the Zero SR/F is a hefty 485 lbs.
6. The 2019 Zero SR/F will be sporting fully-adjustable Showa suspension. Up front, we expect to see a fully-adjustable 43mm Big Piston Separate Function fork, working in conjunction with a fully-adjustable Showa shock. The Showa BPSF has made appearances on many bikes since its introduction, and it’s something we’ve enjoyed in the past.
7. J-Juan Braking Systems takes care of the stopping duties. Zero has relied on J-Juan braking systems for all their models, and the SR/F is equipped with dual 4-piston calipers, clamping on 320mm floating rotors, up front. In the rear, a single-piston caliper works in conjunction with a 240mm rotor.
8. Pirelli Diablo Rosso III tires will help keep the shiny side up.
9. Bosch MSC accommodates cornering ABS, traction control and drag torque control. As with other Zero models, these parameters are adjustable via the TFT dash and within the Zero App.
10. The Cypher III operating system, developed in partnership with Starcom Systems, ups the ante for “smart” features in motorcycling. The SR/F is the first “connected” motorcycle, allowing owners to track their bike’s location and receive updates in case someone tampers with it, share a plethora of riding data, display, and track battery management information, manage software updates and much, much more.
11. Two SR/F models will be available: the SR/F and SR/F Premium. The standard SR/F will set you back $18,995, while the Premium model features 6kW Level 2 charger, heated grips, a fly screen, and aluminum bar ends – all for $20,995.
