The rear suspension, featuring a steel swingarm and hydraulic monoshock with a piggyback cylinder, offers an additional 270 mm of travel, enhancing comfort and stability. Stopping power is provided by single disc brakes at both the front and rear, allowing for reliable and confident braking performance. With a fuel capacity of 10 liters, this bike strikes a balance between performance and practicality, making it a great option for both short jaunts and longer rides. **
