The '''Honda GY6 Engine''' is a small [[four-stroke cycle|four-stroke]] [[internal combustion engine]] developed by the [[Honda Motor Company]].
The GY6 is commonly used to power various kinds of small vehicles, including [[all-terrain vehicle|ATVs]] and [[scooter (motorcycle)|scooters]].

The Honda Motor company has been said{{Who|date=April 2009}} to have perfected the scooter engine design in the 1960s.  Building upon that technology a newer motor, the Honda gy6 engine, was produced in the 1980s.  This is a 4 stroke single cylinder, air or oil cooled design that comes standard with two overhead valves.  Stock horsepower ratings can be found quoted in the range of {{convert|7.8|hp|abbr=on}} to {{convert|12.4|hp|abbr=on}}.  The engine is capable of producing 12,000 rpm and power upwards of {{convert|14|hp}} with modifications according to end users{{Who|date=April 2009}}.  The GY6 engine has a built in swing arm with automatic CVT transmission that is belt driven.  This engine was originally manufactured in {{convert|50|cc|CID|abbr=on|lk=out}}, {{convert|125|cc|CID|abbr=on}}, and {{convert|150|cc|CID|abbr=on}} engine sizes and was found in the Honda Elite and Spacey line of motor scooters.  Honda no longer uses this design on their scooters, but Chinese, Korean, and Taiwanese copies of this engine are readily available.  Current brands of import scooter lines that use the Honda GY6 cloned engine technology include: [[Flyscooters]], Kymco, PGO (imported by Genuine Scooter Company in the USA), Ricardo Motors, Roketa, Strada, SUNL, Tank, Vento, Yamati, among others.

With the wide availability and cheap cost of this engine, Asian ATV manufacturers have started to use this powerplant in their youth line of ATVs (quads) and buggies (off road go karts and trail buggies)  150&nbsp;cc youth quads that contain the GY6 powerplant are found being imported under many brands including Ricardo Motors, Yamoto, Kazuma, and Redcat.  Off road buggies and full suspension go karts that include this style of engine include Carter Brothers Talon Line, Carter Brothers XTV, TJ Powersports Twister Hammerhead, Dazon Raider, Kasea Adventure Buggy, Blade Powersports 150&nbsp;cc, Tomberlin Punisher & Crossfire, Baja Motorsports Dune 150.

With the wide availability of this engine in both older Honda products and newer Asian imports there is a vast amount of information, modifications, and performance parts available to the end user.  User forums such as [http://www.buggynews.com buggy news go karts and off road buggy forum] and  scootdawg forum [http://scootdawg.proboards59.com/index.cgi] offer end users an excellent place to discuss and troublshoot these engines.  Users on these forums have tried a variety of modifications produced by third party vendors such as 4 valved high compression heads, big bore kits, high performance CVTs, performance CDIs, performance carburetors, and performance exhaust kits. The forums are also an excellent source of engine service manuals and general repair guides for tune up and major repair information.
