The Honda 160cc GC160 Series horizontal engine produces 6.9-pound-Feet (9.4 Nm) at 2500 rpm net torque. The compact combustion chamber, overhead cam design, and uniblock construction reduce fuel consumption. Powerful torque across a wide RPM range helps reduce engine speed drop from sudden load increases. The GC160 Series are the lightest engines in their class. They are the world’s first general purpose engine with internal timing belt. The tough resin overhead cam and uniblock construction means durability and quietness. Valve train and gear noise is minimized. Internal timing belt provides quiet operation and precision engineered and machined components result in lower vibration. Honda engines are known for their proven reliability featuring Dual-Lube System for superior engine lubrication, simple construction reduces many potential maintenance needs, single element air filter. They are always easy to use and maintain with easy access oil drain and fill, easily accessible spark plug, and proven lifetime timing belt design. Emissions compliant, CARB and EPA certified.
