Vehicle Information
Yamaha Bear Tracker 250 ATV (1999-2004)
The Yamaha Bear Tracker 250, produced from 1999 to 2004, was a reliable utility ATV. It consistently featured a single-cylinder, 4-stroke, air-cooled SOHC engine with a displacement of 229cc or 230cc, paired with a 5-speed transmission and automatic clutch, including reverse. Model codes such as YFM250X typically indicated the model year or regional variations. While maintaining a largely consistent design, the Bear Tracker 250 received notable updates. For the 2001 model year, a distinct Hunter Edition (YFM250XH) was offered. More significantly, 2003 and 2004 models were equipped with dual hydraulic disc brakes at the front, a substantial improvement over earlier models which likely featured drum brakes all around. Additionally, 2003 models introduced new powder-coated racks for enhanced durability. FAQ:
