Carbon fiber sleeve motor & inverter

The Stark VARG houses the most potent power-to-weight motor of any production motocross bike. Developed and made in Europe, our carbon fiber sleeve motor runs on 360 nominal voltage, churning out 80hp and 9hp per kilogram. It also delivers an incredible 275 Nm of torque on the counter shaft and 938 Nm on the rear wheel. It is designed and optimized to use more than 95% efficiency over the majority of the power range and benefits from a water-cooled aluminum casing that works as a structural part of the chassis. The inverter is also integrated into the motor case in order to reduce mass and simplify the cooling process.


• Stark Future invented the world's smallest inverter for 50-100kW power ranges with patent-pending technology.

• Water cooled motor case that forms part of the structural frame to minimize weight and volume.

• Advanced processor power for algorithms to ensure reliability and safety.

• 30% more peak power than a 450cc. 80hp and 938 Nm of torque on the rear wheel.

• Highest power-to-weight ratio in the motorcycle industry.

• Motor weighs only 9 kg.
