Design

Motorstar Xplorer z200

Zongshen designed the 200GS as economical sport touring bike. A dedicated single-cylinder four-stroke 200 cc engine was chosen for increased fuel mileage, using a push rod valve system for long-distance engine endurance, eliminating risks of timing chain failure due to excess heat during long-distance travel. The push rod design reduces its top speed, allowing a maximum of 120 km/h (75 mph) speed capability. Pushing the z200 to very high rpms increase the risk of valve float. The 200GS push-rod engine uses early Honda technology. Owners in the Philippines discovered that many engine parts are compatible or interchangeable with the parts of a Honda TMX-155 engine.

The design uses heavy sports aerodynamics for stability on highways, and a high capacity fuel tank. The engine is air-cooled, requiring the half-fairing design for proper air flow. The starter clutch will break down easily with longer pressing of the starter switch during automatic start.

The 200GS does not have ports for saddle-bags, and does not include touring accessories upon purchase.
