Its advanced suspension system includes a 40 mm upside-down hydraulic fork with 260 mm of wheel travel in the front and a hydraulic monoshock with a piggyback cylinder in the rear, offering exceptional handling and comfort over rough terrain. The braking system features single discs both front and rear, delivering reliable stopping power for confident rides. Additionally, the bike's compact dimensions and a seat height of 830 mm make it accessible to a wide range of riders, allowing for easy maneuverability and control. **
