With its eye-catching design and robust build, the Hercules 322 stands as a testament to the innovative spirit of the time, appealing to riders who seek both nostalgic charm and spirited performance on the open road. At the heart of the Hercules 322 is a spirited 246cc twin-cylinder, two-stroke engine that delivers a respectable 15.10 horsepower at 5000 RPM.

What sets the Hercules 322 apart are its thoughtfully engineered features and technology. The bike is equipped with telescopic front suspension and a swingarm rear suspension, providing a balanced and comfortable ride even on uneven surfaces. The expanding drum brakes at both the front and rear ensure reliable stopping power, a crucial aspect for a sport motorcycle.
