The front suspension features a 30mm USD fork with 210 mm of travel, offering excellent shock absorption and handling precision. Hydraulic disc brakes on both the front and rear provide reliable stopping power, with a 160 mm front disc and a 140 mm rear disc ensuring confident braking. The adjustable seat height of 680 mm (at its lowest setting) caters to a range of rider sizes, making it accessible for younger racers eager to take their first steps into the world of motocross. ###
