The advanced suspension setup, featuring a CARD 30mm USD front fork and an adjustable piggyback rear, provides a generous 170 mm (6.7 inches) of travel at both ends, ensuring that young riders can tackle rough terrain with confidence and comfort. The braking system is equally impressive, with single discs at both the front (160 mm) and rear (140 mm) for responsive stopping power. Riders will appreciate the 216 mm (8.5 inches) of ground clearance and a seat height of 607 mm (23.9 inches), making it accessible for smaller riders while still offering room to grow. **
