Vehicle Information
Yamaha Moto 4 250 ATV (1989-1991)
The Yamaha Moto 4 250 is a robust utility ATV produced from 1989 to 1991. Known for its reliability, this model featured a single-cylinder, four-stroke engine. Although often referred to as a 250cc, its precise displacement varied slightly between 229.6cc and 250cc depending on documentation, but it is the same fundamental engine. Throughout these production years, the Moto 4 250 was offered as a single model, without distinct trim levels. Suffixes like 'W', 'A', or 'B' in the model codes (YFM250W, YFM250A, YFM250B) simply indicated the manufacturing year and not different versions. There were no major generation or engine changes between 1989 and 1991, ensuring consistency in core specifications. Q: Is this product compatible with my Yamaha Moto 4 250?
