Zero Motorcycles Unveils SR/F Naked Electric Motorcycle

• All-electric naked looks quite aggressive; gets new platform, motor, battery pack and electronics.

• The SR/F has 110PS and 190Nm on tap; Zero Motorcycles claims a range of 260km.

• Battery, motor and other components connected by Cypher III, Zero’s proprietary OS.

Zero Motorcycles has unveiled what they claim is the next step towards the future of electric motorcycles. The all-new SR/F naked electric bike sits on a completely new platform and has all-new powertrain and electronics.

For starters, the aggressive design reminds us of Italian nakeds like the Ducati Monster and MV Agusta Brutale. The seat height is set low at 787mm. Like other high-end electric bikes, it gets an all LED headlamp and 5-inch colour TFT instrument console with smartphone connectivity. A first for motorcycles is the fully connected system where the motor, battery pack, electronics and rider aids like stability control interact with each other and can be controlled via the instrument console or an app on your phone. There will be two variants on offer - SR/F Standard and SR/F Premium.

Power comes from Zero’s new ZF75-10 motor that delivers an impressive 110PS at just 5000rpm and 190Nm of torque. The transmission unit is a clutchless direct drive and power is sent to the rear wheel via a carbon belt. Top speed is a claimed 200kmph. All this power is controlled via a new Bosch’s MSC System synced with Zero’s Cypher III operating system. So now you have cornering ABS, cornering traction control and drag torque control (engine brake control in IC bikes) on offer. It also gets rider modes like Street, Sport, Eco, Rain and a custom mode that can be programmed in 10 different ways.

Another new addition is the Z-Force Li-Ion intelligent integrated 14.4 kWh battery pack, which when aided with regenerative deceleration, offers a claimed 260km of range in city riding conditions. You can charge the bike via a hidden port on top of the dummy tank. The Premium variant takes just 2 hours to charge upto 95 percent and 2.5 hours to charge completely. There’s also a fast charging option that uses a 6kW fastcharger and reduces full charging time to 1.5 hours (1 hour for 95 per cent).

Holding all this in place is a lightweight, steel trellis frame with a superbike-like suspension setup. Yes, the all-electric motorcycle gets a fully adjustable 43mm Showa Big Piston Separate Function Fork and a fully adjustable 40mm Showa rear monoshock with a piggyback reservoir. Tyres too are premium 17-inch Pirelli Diablo Rosso III radials. Braking duties are handled by dual 320mm discs with J-Juan 4-piston radial calipers and a radial brake master cylinder radial and a 240mm disc with single-piston J-Juan caliper at the rear. With a kerb weight of 225kg, the SR/F is quite heavy when compared it to similarly sized petrol-powered superbikes.

Given its performance and the kit on offer, the Zero ZR/F goes up against 800cc nakeds like the MV Agusta Brutale 800RR and Triumph Street Triple RS. Priced at €16,715 (Rs 13.49 lakh) for the SR/F Standard and €18,475 (Rs 14.91 lakh) for the SR/F Premium, the all-electric nakes costs about the same as exotic Italian nakeds from MV Agusta. Sadly, Zero Motorcycles has no plans of setting shop in India anytime soon.
