Suspension is equally impressive, with a 40 mm upside-down hydraulic front fork and a hydraulic monoshock in the rear, providing 260 mm and 270 mm of travel, respectively. Braking is handled by powerful single disc setups at both the front and rear, ensuring reliable stopping power when needed. Additional highlights include a kick starter for simplicity and a comfortable seat height of 830 mm, making it accessible for a wide range of riders. **
