Zero SR: Electric motorcycle with a top speed of up to 200 km/h

What Tesla is to automobiles, Zero Motorcycles is to electric two-wheelers. The driving force behind the Californian manufacturer is Neal Saiki – a former NASA engineer who started developing electric motorcycles back in 2006.
The 222 kg Zero SR is an evolution of the Zero SR/F and the SR/S. It is the first model to be equipped with the ZForce 14.4+ (14.4 kWh) lithium-ion battery and is said to have a range of up to 365 kilometers. (The hottest bike innovations of 2022)

Battery capacity can be increased via software update

In addition to the high energy density of the battery, this range is made possible by efficient cooling through an aluminum housing and heat transfer interface. An important element of the bike are the software updates, which are available in the so-called Cypher Store.

Similar to Tesla, these programs unlock new features and tweaks. The battery capacity is increased to 17.3 kWh; From autumn 2022, the additional power tank will deliver a further 3.6 kWh, which should increase the capacity to almost 21 kWh and enable the maximum range of just 365 kilometers.

The “ZForce 14.4+” battery has a capacity of 14.4 kWh. The “+” indicates that the capacity can be increased with a software update.

It is charged with three kW. This manageable speed can be increased by ten percent with a paid update, which should reduce the charging time from 4.5 hours to 4.1 hours.

It is best to order the top charging option when buying the electric motorcycle and then fill the battery in 1.8 hours. Due to the efficiency and the compact design of the drive train, passive air cooling is sufficient.

Up to 81 kW and a top speed of 200 km/h

The same applies to the engine: If you dig deeper into your pocket, you get more power. In the basic configuration, the permanently excited, brushless ZF75-10 electric motor delivers 55 kW (74 hp) and a torque of 165 Newton meters. This should allow the SR to reach a top speed of 167 km/h. The upgrade includes 81 kW (110 hp), 199 Nm and a top speed of 200 km/h.

The Zero SR comes from the factory with the driving modes “Rain”, “Eco”, “Standard”, “Sport” and “Canyon”, which can be supplemented or refined with many individually adjustable driving programs.

The power can be increased to 81 kW with a software update. Then a top speed of 200 km/h is possible.

The Cypher store is the central platform if you want to optimize the Zero SR. In addition to the performance tuning, the stability control (comes from Bosch) and the navigation system can also be optimized. With the display you always have all functions in view.

Prices from almost 20,000 euros

The single-track electric speedster costs a whopping 19,390 euros. It has a steel lattice frame with a coaxial Power Pivot chassis and a 43 millimeter Showa upside-down fork (Big Piston – Separate Function Fork) with adjustable spring preload, compression and rebound damping. At the rear there are Showa gas pressure shock absorbers with a piston diameter of 40 millimeters including an external reservoir, where the spring preload, compression and rebound damping are also adjustable.

The front wheel is decelerated with Bosch Base MSC brakes (two four-piston radial calipers) and 320 x 5 millimeter brake discs. A 240 x 4.5 mm brake disc with a single-piston floating caliper is installed on the rear tire.
