La atención exelente, muy rápido y atento, el kit va de lujo.
Excellent setup, would recommend to any grom owner.
Very knowledgeable and helpful. Will definitely be coming back to order more parts.
Great person to work with. Bike feels amazing after the stage 3 kit and tune. Great customer service and fast turn around.
The DH Motoring Stage 3 Package includes the following:
DHM ECU Flash
DHM High Compression Stock Bore Piston
TB Parts Camshaft
NGK CR9E Spark plug with spacer
Honda Monkey Stage 3 kit is available HERE
Combined with your aftermarket intake and exhaust, this is the most you can get out of your Grom without doing any head work. After dyno testing we were repeatedly seeing 13.5hp at the wheels (SAE) run after run! The Stage 3 package makes more power than a stock Grom at every RPM and double the horsepower at 9000+ rpm! 91 octane fuel is absolutely required. Any fuel with a lower octane rating may result in engine damage!
You can choose to receive a preflashed ECU instead of sending yours in. You can also choose to receive a new cylinder matched to the piston if yours is worn.
This product page is for customers that do not currently have a DHM flash or cam package. If you already own our reflash or cam package, you can purchase the Stage 3 Upgrade HERE.
