With front and rear disc brakes featuring floating bearings, riders can count on strong and responsive braking, which is crucial in competitive scenarios. Additionally, the bike's ground clearance of 375 mm and an adjustable seat height of 960 mm ensure that it can accommodate a range of riders, making it versatile for both beginners and seasoned racers. ####
