The Yamaha XF50 (marketed as the C3 in North America, Vox in Japan, and Giggle in Europe) is a liquid cooled 49cc four-stroke motor scooter made by Yamaha Motor Company. It is notable for the 9-gallon capacity of the under-seat storage compartment, and a distinctively "box"-like rear section and seat which accommodates it.

Yamaha Motor Company Limited is a Japanese manufacturer of motorcycles, marine products such as boats and outboard motors, and other motorized products. The company was established in 1955 upon separation from Yamaha Corporation, and is headquartered in Iwata, Shizuoka, Japan. The company conducts development, production and marketing operations through 109 consolidated subsidiaries as of 2012.

Fuel Economy

The United States Environmental Protection Agency mileage estimates for the C3 are up to 115 miles per gallon (2L per 100 km), depending upon how it is ridden, maintenance, road conditions, cargo, and driver/passenger weight.

United States Environmental Protection Agency Agency of the U.S. Federal Government

The Environmental Protection Agency (EPA) is an independent agency of the United States federal government for environmental protection. President Richard Nixon proposed the establishment of EPA on July 9, 1970 and it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the President and approved by Congress. The current acting Administrator following the resignation of Scott Pruitt is Deputy Administrator Andrew Wheeler. The EPA is not a Cabinet department, but the Administrator is normally given cabinet rank.

Speed Limitations

In North America, the C3's top speed is limited by the factory via a washer on the end of the boss shaft of the V-belt transmission. This washer limits how close the belt sheaves can come together, thus limiting the potential front diameter of the belt at full throttle. Removal of the washer is possible with simple tools and will increase the top speed to an RPM limited of 40 mph, although damage caused by modification is excluded from the Yamaha warranty. [1]

In Europe the Giggle Primary sheave variator (Part No 15PE76200000 ) is different from its US C3 version (Part No 3XYE7620010). This limits the Giggle to 31 MPH, even down hill. However the US version is freely available in the UK, NL & Germany. With no further modification it will allow the Giggle to get to 38MPH on level roads and >40 mph down hill. The effect of removing the tiny washer that sits between the two 'cones' is a gain of 1-2 mph however research has shown that moving the washer behind the primary Sheave has the same effect and improves the geometry of the V-belt. These modifications may contravene the law in certain EU states and void insurance !

The Giggle also has a slightly lower rev limit.
