The Insork EM77 embodies the timeless appeal of café racer motorcycles. It’s characterized by minimalist design, low-slung handlebars, round headline, and streamlined profile. This design philosophy pays homage to the classic motorcycles of the past while integrating contemporary comforts.
Performance and Powertrain
At the heart of the EM77 lies a centrally mounted Permanent Magnet Synchronous Motor (PMSM). This motor clocks in with a rated power output of 10.5 kW and a maximum efficiency of 94%. It’s liquid-cooling enables the motorcycle to achieve a top speed of 140 km/h (87 mph). As with most electric motorcycles, acceleration is brisk. The EM77 reaches 0 to 50 km/h in just 2.8 seconds and 0 to 100 km/h in 6.5 seconds.

Battery and Range
Equipped with a high-voltage 144V 73Ah battery, the EM77 boasts a capacity of 10.5 kWh. This battery configuration allows for a commendable range of up to 200 kilometers under real-world driving conditions, averaging speeds of 80 km/h. Such a range positions the EM77 as a practical option for both urban commuting and longer journeys.
The EM77 features a built-in charger compatible with Type 2 AC charging stations and supports a charging rate of 3.3 kW. This compatibility ensures that riders can conveniently recharge the motorcycle at most public and home charging stations. According to Insork, a full charge can be achieved in approximately three hours, minimizing downtime and enhancing usability.
Durability and Reliability
Insork emphasizes the durability and reliability of the EM77’s motor and Electronic Control Unit (ECU). These components have undergone rigorous testing over five years of mass production and have been successfully integrated into over 50,000 electric motorcycles. Designed to maintain consistent performance even in extreme temperatures, the cooling system ensures optimal functionality regardless of environmental conditions.
Technological Features
A notable feature of the EM77 is its 7-inch TFT display, which provides real-time updates on key performance metrics. This interface allows riders to monitor the motorcycle’s performance continuously without diverting attention from the road, thereby enhancing both safety and control.
Safety remains a priority for Insork, as evidenced by the inclusion of a braking system supplied by Nissin, complete with Anti-lock Braking System (ABS) as a standard feature.
