Continuously evolving series of commercial bikes


Equipped with a double-muffler type 125 cm³ 2-stroke air-cooled 1-cylinder engine with proven and impressive durability, the K125 is a commercial bike with ample performance for a wide range of applications. A full transistor type ignition system was adopted during a minor change to realize steady ignition. The fuel tank was also redesigned, raising its capacity to 13 liters and extending the riding range.
