YAMAHAGrizzly 350 4x4 2005 - Present

　　The 2005 Grizzly's four-stroke engine made excellent torque, and this came in handy in four-wheel-drive mode. Slowing the bike down and pulling its way up hills, the Bruin made quick work of everything we threw at it. This engine yet again proves how well Yamaha's four-stroke engine program is because it revved quick and hard, and not once did we wish for a two-stroke engine.
