The motorcycle is equipped with drum brakes, both front and rear, each measuring 152 mm in diameter, offering reliable stopping power that instills confidence in any riding scenario. The telescopic front suspension and swingarm rear suspension with dual shocks further enhance the riding experience, ensuring that bumps in the road are managed with grace and control.
