HP 125cc / 150cc 4T GY6


125cc / 150cc GY6 PERFORMANCE PARTS

The Honda GY6 Engine is a small 4-stroke internal combustion engine developed by the Honda Motor Company. The GY6 is commonly used to power various kinds of small vehicles, including ATVs and scooters.

The Honda Motor company has been said 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 7.8 hp (5.8 kW) to 12.4 hp (9.2 kW). The engine is capable of producing 12,000 rpm and power upwards of 14 horsepower (10 kW) with modifications according to end-users.
The GY6 engine has a built in swing arm with automatic CVT transmission that is belt driven. This engine was originally manufactured in 50cc, 125cc, and 150cc 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), Lance, Roketa, Strada, SUNL, Tank, Vento, Yamati, among others.

With the wide availability and affordability 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. The end-users have tried a variety of modifications produced by third party vendors such as MRP, Polini, Malossi, Dr. Pulley to name a few with 4 valved high compression heads, big bore kits, high performance CVTs, performance CDIs, performance carburetors, and performance exhaust kits.
