In the rear, the hydraulic monoshock with a progressive link system provides 220 mm of travel, ensuring a plush ride without sacrificing performance. Stopping power is delivered by a powerful single disc brake setup, featuring a 300 mm front disc and a 220 mm rear disc, both equipped with floating calipers for improved modulation. The bike’s lightweight design, at only 120 kg, combined with a seat height of 880 mm, offers an accessible riding experience for riders of various skill levels.
