Yamaha Timberwolf 250 ATV (1992-2000)
The Yamaha Timberwolf 250, produced from 1992 to 2000, was a robust and reliable utility ATV. It was consistently powered by an air-cooled, 4-stroke, SOHC, single-cylinder engine with a displacement of 229cc or 229.6cc. This ATV featured a 5-speed transmission with reverse gear and a shaft drive system, ensuring dependable performance for various tasks. The core engine design remained stable throughout its production run from 1992 to 2000.

The 4x4 model continued until 2000. The initial 1992 model year also featured an all-new body and chassis, providing modern styling and functional design for its time.
