The two power pulses of the Brute Force 650s V-twin engine reduce stress on the CVT components compared to the one large power pulse of a big-bore single cylinder engine extending belt and CVT service life. CVT sheaves are manufactured of high-pressure cast, high silicon aluminum (same as pistons) for best durability. Kawasaki Engine Brake Control uses speed and direction sensors along with an electric servo for smooth operation. This system detects the ATVs speed, direction, and deceleration electrically. When the conditions are satisfied, the electric servo moves out to hold the CVT drive pulley closed thereby connecting the driving pulley with the driven pulley through the belt and then generating braking force from the engine. The Kawasaki Engine Brake Control is an automatic engaging system. Theres no need to apply throttle for the system to engage. Coasting forward in gear, the Kawasaki Engine Brake Control automatically engages to provide engine braking force. Additionally, whenever the key is turned off, a learner program in the engine brake controller measures and then self adjusts for belt wear to ensure consistent engine braking operation. Kawasaki Engine Brake Control safety features ensure that the engine braking force only works when the ATV is moving forward and vehicle speed is more than 3 km/h. FINAL DRIVE Efficient through engine propeller shaft is lubricated using the same oil shared with the engine and transmission. The all-in-one case saves weight and controls the exacting tolerances between components. Through engine design allows for very short, light, rigid drive shafts for the front and rear final drives. Straight alignment of the drive shaft to the front final drive case delivers power through sealed splines with no U-joints required. New drivetrain revisions include: a thinner, lighter propeller shaft, yoke components have been trimmed down, select parts have been unitized, and grease nipples have been removed from the drive shaft spiders. Compact final gear case design contributes to incredible ground clearance allowing the KVF650 to go where others fear to tread. The rear final drive housing carries Kawasakis renowned, internal, wet brake system. The brake operates in the final drives oil bath completely sealing it from wear causing mud, dust, water, etc. External brake lever return spring replaces the internal brake lever return spring to provide better and more consistent brake feel at the lever.
