The front suspension provides a generous travel of 170 mm, smoothing out bumps and rough surfaces while maintaining stability. The seat height of 840 mm is designed for accessibility, accommodating a broad range of riders. With an electric starter, the Sting 125 ensures that you're always ready to roll at the push of a button.
