At the heart of the Teryx4 is Kawasaki’s 749cc V-Twin. The single overhead cam engine is similar to the beast that powers the standard Teryx and Brute Force 750 ATV, but has a host of refinements to suit the needs of a four-seater. It uses an electric start system to churn over dual pistons inside 85 x 66mm bore and stroke cylinders with a 9.3:1 compression ratio. The oversquare, 90-degree V-Twin cranks out gobs of usable torque and Kawasaki claims the proven engine has 15% more top-end power thanks to new equal-length exhaust headers and redesigned camshafts. Tuned dual 36mm throttle bodies with new 12-hole injectors provide the fueling. Engine internals are slightly massaged as well with changes to the piston pins, connecting rods, shift drum and crankshaft journal bearings. We didn’t have a chance to drive it back-to-back with a two-seater, but the Teryx4 does feel like it has slightly more pep. It’s rated to tow 1300 pounds from its standard two-inch hitch receiver.
The engine breathes through a larger cartridge-style air filter with an intake chamber that is nearly three times as large as the two-seat Teryx (T2). Also, the intake has been repositioned from the console between the driver and passenger to underneath the front hood. The radiator is larger than the T2 with a bigger fan to push hot air. In addition, an extra fan has been installed on the underside of the chassis to help blow cool air across the mid-mounted engine itself. The secondary fan kicks on whenever the radiator fan is activated. There’s a blower warning light on the dash but we never saw it light up, nor heard the radiator fan kick on during an entire day of driving. Obviously the oversized radiator does a good job.
