Motorcycle specifications Zero MotorcyclesSR 2017 Feel like eating 1000?

Impressive torque. Spectacular acceleration. Instant response. The Zero SR boosts performance with a reinforced controller (775 A) and higher-temperature motor magnets. The result is a remarkable 146 Nm of net torque, more than any sportbike under 1,000 cm3. With arm-stretching acceleration and superior sustained top speeds, the Zero SR aims to make the gasoline-powered competition bite the dust.

Range in excess of 250 km and a service life of + 550,000 km

The Zero SR features advanced chemical cell and battery management systems for greater capacity and longer range. The ZF13.0 power pack gives you up to 325 km and is designed to last as long as your bike. The result of cutting-edge research and development: each element of the power pack is individually controlled and monitored to ensure optimum performance.

Power Tank technology - up to 325 km in town

The Z-Force® Power Tank provides an additional 3.3 kWh of storage capacity to the power pack of any Zero S or Zero SR motorcycle 2014 or later. Available as an option, the Power Tank can be added at any time, at or after purchase, increasing the maximum battery capacity to 16.3 kWh. With this kind of energy, a rider can cover up to 325 km in town or 163 km on the freeway at 113 km/h.

Z-Force® engine - up to 52 kW net power, 146 Nm...and surprising efficiency

Zero Motorcycles designed the Z-Force® engine from the ground up to be compact, efficient and powerful. It delivers exhilarating acceleration to a top speed of 164 km/h on the Zero SR. Fully air-cooled, the engine provides a fantastic driving experience with no routine maintenance. When you slow down, the motor generates electricity which is fed back into the power pack to increase range.

Chassis and bodywork

The double-cradle frame is built exclusively from aircraft-grade aluminum. Lightweight and robust, it's one of the main reasons for the exceptional riding precision of these bikes. Designed to have a low center of gravity, the bikes are highly maneuverable and responsive. The refined appearance is rounded off by elegant bodywork with a modern, dynamic, stripped-back look. The body's fuel tank area features an integrated, lockable and removable storage compartment. The tank area can also be replaced by the Power Tank accessory for greater autonomy.

Showa suspension

Zero Motorcycles worked closely with Showa to develop the suspension systems. These effectively handle small bumps, predictably control larger impacts and smooth the action in all conditions. The rigid torsion of the front end offers improved handling, while the hollow front axle reduces unsprung weight. Suspension settings are fully customizable to meet the requirements of most riders.

Wheels and ABS

The Zero SR features Bosch's advanced anti-lock braking system (ABS). The large 320 mm diameter unsupported front brake disc increases stopping power. The Zero SR is fitted with Pirelli tires that provide great traction, excellent durability and excellent road feel. The tires are mounted on elegant, durable cast-alloy wheels.

Dashboard and controls

The instrument panel is designed by Zero to provide quick, useful and accurate information such as charge level, power output and selected riding profile. You can juggle the three riding modes using the ergonomic switch on the right to better determine your riding needs: sport, eco, custom. The dashboard display is a blue backlit LCD screen. It blends in perfectly with the front of the motorcycle. Want more information about your motorcycle while you're riding or at home? Try the Zero Motorcycles app.

Zero Motorcycles applications

With the Zero Motorcycles app, you have access to detailed information about your motorcycle, such as remaining recharge time, average watts per kilometer, total recharge cycles and much more. When you're stationary, the app lets you set the performance profile of the customized riding mode, adjusting parameters for maximum speed, maximum torque and maximum regenerative braking. When you're riding your bike, your cell phone transforms into a personalized dashboard that gives you real-time, detailed information about your bike. Synchronized with Bluetooth, the application works on iPhone and Android-based mobile devices.

Clutchless drive - Instant torque with just a little difference

Featuring clutchless direct drive, the Zero S and Zero SR are designed for rapid acceleration and maximum efficiency. With its more efficient motor, the Zero SR benefits from higher gearing to reach a top speed of 150 km/h. With no need to shift gears, both models deliver controlled, powerful acceleration until you reach your desired speed. The carbon fiber belt eliminates minimal friction losses and increases overall range. What's more, it also plays a key role in eliminating powertrain maintenance and noise.

What about recharging?

Zero Motorcycles' charging options are designed to suit your lifestyle. Every Zero motorcycle comes standard with a simple, lightweight cable that plugs into any household outlet.

For use at home or in the office, Zero Motorcycles' fast, expandable charger system can dramatically reduce recharging times. The system uses up to four independent (external) 1 kW chargers, which are used in combination with the motorcycle's standard (built-in) charger.
