2021 Zero SR/S: An EV Sport Touring Option With Overwhelming Torque Numbers
Contents
Along with the Zero SR/F (aptly nicknamed ‘The EV Streetfighter’), the American-based EV motorcycle manufacturer also produces this SR/S model. The SR/S is a sport-touring version of the SR/F featuring full-fairings, sitting on top of their 2021 lineup as the second most expensive motorcycle they offer.
Building a package dedicated to sport touring on an EV motorcycle platform proves quite difficult due to range limitations and maximum battery capacities but Zero figured out a way to make it happen.
Much like the Zero SR/F, the SR/S share the same motor and battery design. By comparison, the 2020 Ducati Panigale produces a ‘measly’ 91 lb-ft of torque. The SR/S on the other hand? 140 lb-ft of torque. A 35% increase compared to the king of 200 horsepower supersport motorcycles.
Just like the SR/F, Zero Motorcycles provides S edition with two configurations; standard and premium with the ladder offering quicker charging capabilities and a few other small features to make your EV motorcycle experience more enjoyable.
The 14.4 kWh Z-Force Li-Ion batteries provide riders with a comfortable range of 123 miles after a 1.8 hour charge time with the 6 kWh rapid charge option (8.5 hours in a standard outlet with EVSE cord). You may ask yourself, how could its drivetrain be so similar to the SR/F yet manage to get a further range? Due to the all-new aerodynamic fairings inspired by aerospace design, riders will enjoy a 13% increase in range on the highway purely due to the way air will be traveling over the bike.
The 2021 Zero SR/S starts at $19,995 USD / $28,626 CAD.
