Its lightweight chassis, tipping the scales at only 75 kg (165.3 pounds) with fluids, enhances maneuverability, while the 2.5-liter fuel tank provides ample range for short journeys without frequent refueling stops. The expanding brakes, both front and rear, ensure reliable stopping power, making this bike not just fun but safe as well.
