The all-electric Zero SR/F has been revealed and it
looks like an electric motorcycle that would almost inconspicuously blend into
the crowd of internal combustion bikes. Zero Motorcycles would offer the SR/F
in two variants – Standard and Premium – but the spec sheets, excluding the
quick charger, are identical. The Standard version is priced at US$ 18,995
while the Premium variant can be purchased for US$ 20,995.

With a full charge, the ZF14.4 lithium-ion battery
is claimed to deliver an impressive range of 259 km, which can be
further extended to 322 km)with the Power Tank. The battery pack
feeds power to the ZF75-10 motor that delivers 190 Nm of torque
and 110 hp of power that can propel the SR/F to a top speed of 200
km/h. The power delivery to the rear wheel is optimised using a proprietary
concentric motor and swingarm pivot design.
Users can customise the output with the ride modes.
The SR/F gets Street, Sport, Eco, Rain and up to 10 programmable custom modes. Shock absorption department at

The SR/F is claimed to be the world’s first fully
“smart” motorcycle. The motorcycle gets Cypher III, a customizable dash and

full-colour 5” TFT LCD screen can toggle between various functions as per the
rider’s needs. The display features switching ride mode on the go, cruise
