This model is powered by a 8-valve, liquid-cooled, SOHC, 976cc engine, placing it in the big bore displacement class (650cc class and above). It produces an incredible 101HP, making this one of the most powerful Side by Sides in 2015.Its standard electronic fuel injection makes for a more powerful and efficient engine through automatically mixing the right amount of air and fuel, but this comes at the cost of mechanical simplicity, and can result in more maintenance down the road.With throttle bodies measuring 54mm in diameter, this engine can inhale 17% more air than its big bore competitors.A cylinder bore of 3.58in and a stroke of 2.95in make this engine oversquare, meaning that it is more powerful than a similarly-sized engine with a smaller bore.
