The Big Bear 350 was Yamaha Motor’s first 4WD ATV model and was released in markets like the U.S. and Canada in 1986. Much of the latest technology at the time was employed in this model, such as a 350cc 4-stroke engine with an oil cooler, a high/low 10-speed transmission with a reverse gear, and front wheel torque control differential (TCD). The product matured over the years through model changes and the addition of new variations to increase its appeal and it went on to become a popular long seller.
