2021 SR/S Zero Electric Motorcycle Review Specs Price

2021 SR/S Zero Electric Motorcycle

The SR/aerodynamic S’s fairing, inspired by cutting-edge aerospace design, lies at the heart of its groundbreaking design. Everything about Zero Motorcycles is based on the premise that form follows function. To get the best of both worlds in terms of economy and range, lean back in the cockpit and go below the fairing on an SR/S. There is an obvious difference in how your body feels and appears when you sit up and ride.

2021 SR/S Zero Electric Motorcycle – Features and Price

2021 SR/S Zero Electric Motorcycle

Elevated Design

Because of the new SR/full-fairing Ss, the parking lot is now the focus of onlookers in traffic lanes. It extends the bike’s overall range by 13% compared to the naked SR/F because of its aerodynamic cockpit design, which wraps closely around the trellis frame.

Premium Comfort

The lower foot position and higher handlebar height on the new SR/S provide a more upright and comfortable riding posture for riders. Comfortable two-up riding is possible because of the lower pegs and larger seating area, making for a lifetime journey. The suspension has been fine-tuned to provide a more luxurious ride.

Effortless Power

The ZF14.4 lithium-ion battery provides the SR/S a maximum driving range of 200 miles with the optional Power Tank. Power and energy density are among the highest in the industry; an aluminum heat-sink casing and thermal transfer interface provide consistent cell cooling.

Effortless Power

The Zero SR/S can reach a top speed of 124 mph thanks to the ZF75-110 10’s horsepower and 140 ft-lb of torque. Using a passively air-cooled small chassis, Zero’s well-known internal permanent magnet brushless architecture delivers performance and efficiency that are unmatched in the industry.

Effortless Power

With our Rapid Charge System, you can configure the bike to charge using any standard Level 2 charger with a capacity of 3, 6, 9, or 12-kilowatts, depending on your needs. At up to 38 miles of range per hour of charging (mph), at 6 kW, it can reach 76 mph and at 12 kW, it can get a full 95 percent of the battery pack’s capacity in only one hour’s worth of charging.

Effortless Power

Concentric motor and swingarm pivoting are used in the optimal architecture to maintain constant drive-belt tension and maximize torque distribution to rear wheels. With a custom-designed large-bearing swingarm pivot, a narrow chassis waist allows better rider ergonomics and bike handling.

Effortless Control

Using Zero’s proprietary Cypher III operating system, all motorcycle systems are connected. Consistent and good riding performance is provided by giving a precise and smooth performance.

Effortless Control

The next-generation software and dash interface on the SR/S allow the rider to customize the bike’s performance. The SR/S can navigate the road in a variety of conditions thanks to its Street, Sport, Eco, Rain, and up to 10 user-configurable custom modes.

Effortless Control

For dynamic acceleration and more excellent stability regardless of the road surface or conditions, the MSC System is incorporated into SR/S. Only when the MSC is used in conjunction with Cypher III that all of the MSC’s potential is realized that the MSC shines.

Effortless Control

It’s pretty thin—incredible force. Reactive and dynamic riding is provided by the steel trellis frame, innovative swingarm, and high-quality Showa suspension components. There are many weight savings and mass centralization with a weight-optimized powertrain and dual radial front brake system, which makes stopping as exciting as speeding up.

Effortless Connection

Customize your dashboard to your liking. The full-color 5″ TFT LCD makes it easy to pick out the data you want to see and ensures that you do. To name a few of the conveniences provided by multimode navigation: on-the-fly mode switching, cruise control, heated-grip control, and more.

2021 SR/S Zero Electric Motorcycle

Effortless Connection

Always connected to mobile networks, the SR/S app receives data. The journey, as well as the bike’s current condition and position, are always available. Bike status alerts, charging, ride data sharing, and system upgrades and updates.
