One of the drawbacks of a motorcycle is the heat dissipating off the engine and exhaust that inevitably transfers onto the rider. During normal conditions, a bike’s engine can range from 155 degrees Fahrenheit to 230 degrees Fahrenheit. So, not only is it extremely hot to the touch, but that heat can travel upwards and make things uncomfortable, to say the least. In addition to the engine and exhaust heat, a hot day with the sun bearing down on you can exacerbate an already scorching experience.
Fortunately, the FTR features rear cylinder deactivation, which shuts off the rear cylinder when certain conditions are met to help provide the rider a break from sweltering temperatures coming off the engine. For the FTR, the coolant in the V-Twin engine has to reach more than 176 degrees Fahrenheit, while the outdoors has to be at least 60 degrees Fahrenheit. In addition, you’ll need to be under 2,200 RPM and have your hand off the throttle.
