Zero SR/F For Sale
What Is It?
The Zero SR/F is a premium naked bike and is powered by an air-cooled Z-Force 75-10 motor, which is the round orange bit just behind the massive battery, producing 110 bhp peak power and 53.6 bhp continuous power at 5,000 rpm.
The "10" in the name stands for the larger 10 cm rotor (7 cm on the previous Zero models) and as with most electric bikes peak torque is achieved almost instantly.

For £2,000 extra the Premium edition gets you a fly screen, heated grips, bar ends and the 6 kW on board charging system. It weighs 6 kg more however it's worth noting that the fast charging system is normally a £2,640 extra. All together that's £20,435 for the fast charging model plus cable to plug it in but you do save a bit with the Government's electric vehicle grant.
All of that is important because in Standard trim and using the UK charging cable the battery charges to 100% in a hefty 4.5 hours but in Premium trim this can drop to 2.5 hours if you are using fast public charging points or have one specially installed at home. For piece of mind you also get a five year warranty on the ZF14.4 Li-Ion battery.
Like many of the cruisers out there the final drive is via a belt, which reduces the usual chain maintenance tasks and adds to the overall quiet package.
The party piece, seen on and loved by owners of the Honda NC series, is the Frunk with dual USB chargers. That's a handy storage space where the fuel tank would usually be, although there's a good chance you will end up filling much of it with the charging cable.
The bike is connected to the internet and the associated app is worth a mention because it includes some cool features like tracking the bike's location, setting times to charge so you can take advantage of off-peak tariffs and alerts to your phone when it reaches a desired level of charge. The 10-spoke 17" wheels take a Pirelli Diablo Rosso III 120/70 tyre at the front and 180/55 at the rear.
Accessories include the 770 mm low seat, 810 mm high seat, fly screen, heated grips, Aluminium bar ends and 3.6 kWh PowerTank extra battery which fits in the storage area.
- 2019-2020: Red, blue
- 2021: Grey, pale green
The cooling fins on the battery and motor not only look cool but are part of the thermal design. The motor gets hot when it's powering the bike so the fins are front to back, while the battery gets hot when charging so they are bottom to top. Clever stuff!
2020: Faired SR/S version launched with softer suspension, larger pillion seat, lower pegs, higher bars and cool mirrors.
