Keep your cool on a sweltering summer day. Engineered to maximize rider and passenger comfort in high temperature situations, the CoolFlow Fan is the perfect addition if your bike is subjected to parade duty, rush hour traffic, or extreme temperature environments. Unlike traditional fan kits that try to cool the engine by blowing air across the cylinders and often onto your legs, the CoolFlow Fan Kit keeps the riders comfortable by pulling air away from the rear cylinder and exhaust pipe, and directing it toward the ground. The fan suction generates a low pressure region near the riders to balance the natural "up and out" convection air flow in the area behind the engine. The wind-tunnel tested fan is tucked away above the transmission, and when combined with mid-frame air deflectors, significantly drops the temperature the seated rider experiences. The CoolFlow Fan features switched On/Off/Auto operation. In the "ON" mode, the fan is active at low speeds, and will turn off when the bike reaches 40mph. As speed drops, the fan turns back on at 35mph. This logic program prevents the fan from cycling on and off during low speed changes. In the AUTO setting, the fan operates based on a combination of speed parameters and specific engine and ambient temperatures. Built to withstand the harsh motorcycle environment, the all-weather CoolFlow Fan is 100% waterproof and includes everything you need for installation. The plug-and-play design is integrated with the vehicle electronics, so "On/Off/Auto" fan operation is indicated in the odometer screen. Your dealer will enable this function in the Electronic Control Module (ECM) and you're ready to roll.
