Yamaha Big Bear 400 ATV

2009 Big Bear 400 ATVs were built in Newman, GA, USA and features I really like are the large capacity fuel tank with a built in fuel gauge and a great turning radius. Blazing a new trail while hunting is made easier with Big Bear features, you will appreciate being able to maneuver around obstacles in tight quarters.

The 2009 Yamaha Big Bear 250 ATV featured the longest wheelbase in its class and provided durable off-road transportation when the going got tough. Integrated floor boards protect rider and ATV from dirt and debris while carrying 165lbs of cargo on the racks and towing another 728 via a bumper hitch. A strong 230cc, 4-stroke, air-cooled single over-head cam engine and 5-speed transmission with reverse give the Big Bear a high performance rating.

Yamaha offers optional Big Bear 250 accessories including a front brush guard, front brush plate, front A-arm skid plates and a rear differential skid plate and over fenders. Talk about taking care of business! The Big Bear 250 is the 'little brother' of the Grizzly but it is ready to take you, and all your gear, into hard to reach areas.
