The Suzuki FZ50 was a noped made by Suzuki from 1978-1983. This bike was marketed under a few different names, FZ50 Youdy/Rascal/Suzy and FS50 in different countries, mechanically the same with slight changes in trim. Although it has small wheels, it falls into the "noped" category due to its bare tube frame and use of pegs, as opposed to a floorboard.
As opposed to the popular Suzuki FA50, the FZ50 didn't sell as well, mainly because it doesn't qualify as a moped in most states. The stock engine generates 3.2 HP, and most go over 30mph with no modifications. They are arguably better bikes than the FA50 due to the higher horsepower rating, bigger carburetor, and the two speed automatic transmission. The transmission holds 900ml of 10w-40. Second gear engages at about 10mph.
The FZ50 features oil injection, a crude gas gauge on the tank, front and rear racks, plastic legshields, and 12" x 3.00 5-star mag wheels. The ride is very smooth thanks to leading-link front suspension and a beefy rear mono-shock. Colors available were orange, red, black and blue.
The FZ50 piston, cylinder, head, and exhaust are interchangeable with the Suzuki FA50. Therefore a few aftermarket parts do exist, namely the Simonini expansion chamber exhaust, and a few larger bore, 45mm piston (59cc) kits exist. The FZ50 came equipped with a 14mm Mikuni VM round slide carburetor.
Note: the Suzuki FZ50 Owner's Manual listed here is actually a complete listing of the parts on a FZ50. For servicing procedures refer to the Suzuki FA50 Service Manual under the Suzuki FA50 page. Common repair features for both of these mopeds are covered in detail. Hopefully someone will upload a copy of the Suzuki FZ50 Service Manual on this site.
