Case

A fast-growing electric motorcycle manufacturer in Southeast Asia was facing challenges with its drivetrain system. Riders reported excessive noise and vibration during acceleration, especially on uphill roads, which affected both comfort and brand perception. The issue stemmed from standard gears that could not withstand high torque while keeping noise levels low.

DDGear worked closely with the engineering team to develop custom small-module helical gears and reduction gears tailored for high-speed electric motorcycle motors. By using carburized alloy steel and precision grinding, the gears achieved ISO Class 4 accuracy and significantly reduced backlash. The result was a smoother torque transfer, lower operating noise, and improved durability under continuous heavy load.

After integration, the client reported a 35% reduction in NVH (Noise, Vibration, Harshness) and an increase in drivetrain efficiency. Riders experienced a more stable and enjoyable ride, even at high speeds or challenging terrains. This success helped the brand differentiate itself in the competitive electric motorcycle market, boosting sales and customer satisfaction.
