Product Information
Honda GX120 Engine Update
In early 2025, Honda temporarily paused production of their GX120 engines while undergoing updated US EPA (49-state) certification. As a result, this family of engines became unavailable for a period.
We are pleased to confirm we now have stock of the updated 2026 Honda GX120 engines which are back on sales and available for next day delivery.
Please note: The updated 2026 GX120 engines will be certified for use in the UK, EU and Australia complying with EU Stage V exhaust emissions and Australia RCM regulations. They are NOT for use in North America.
