Engine Features
This 558cc 4-stroke SOHC 4-valve liquid-cooled engine is derived directly from the industry-leading Grizzly 700 powerplant.
Ceramic-composite cylinder liner provides outstanding durability and heat dissipation; 92mm forged piston is light and strong and rides on a carburized chrome-moly connecting rod.
Two-lobe overhead cam and a pair of needle-roller rocker arms reduce friction by 50 percent for increased fuel efficiency and torque.
The cylinder head has been optimized to deliver excellent throttle response and low-end power, roller-bearing rocker arms to reduce friction for fuel efficiency and torque.
Gear-driven crankshaft balancer shaft and 4-position rubber engine mounts reduce vibration.
Yamaha Fuel Injection uses a Mikuni 40mm throttle body and idle speed control valve to provide easy cold starts and flawless fuel delivery in nearly any condition, from below sea level to 15,000 feet.
Pushbutton electric start with seven-disc torque-limiting damper assembly to protect the starter motor.
Stainless steel exhaust system features aluminum heat shields and a screen-type spark arrestor for great power with minimum noise output.
High-capacity aluminum radiator with fan motor delivers maximum cooling efficiency and is positioned high in the frame for optimal protection.
Five-position shift lever with L, H, N, R and P gates has a light shifting feel with easy engageme
