Compact combustion chamber

Compact combustion chamber, overhead cam design, and uniblock construction

GC series, GS series

A truly innovative combination of a compact combustion chamber, overhead cam configuration and uniblock construction significantly reduces fuel and oil consumption as compared to conventional side-valve engines.

Honda’s simple design has made the GC and GS Series lighter and more compact than any engine in their class. Plus, simple construction has minimized the number of parts, making the engine more reliable and easier to operate.
