Up front, the upside-down hydraulic fork with 40 mm diameter offers 110 mm of travel for improved handling, while the rear asymmetric swingarm with a monoshock provides 120 mm of travel for a smooth ride over bumps. High-performance braking is assured with a 300 mm stainless steel disc and a 4-piston caliper at the front, complemented by a reliable single disc at the rear.
