WheelsOfGrace.com | Volume 12 Issue 3 | 11 skirt has a low-friction coating. Low-tension piston rings reduce friction, which improves performance. The top ring land is anodized to enhance durability. Oil cooling jets are aimed at the bottom of the pistons to help dissipate combustion heat. Four-Valve Cylinder Heads* Four-valve cylinder heads (two intake and two exhaust) permit the largest-possible valve area. Double Overhead Camshafts (DOHC)* The Revolution Max 1250 engine is equipped with separate intake and exhaust camshafts for each cylinder. Hydraulic Lash Adjusters The Revolution® Max 1250 engine features roller-finger valve actuation with hydraulic lash adjusters. This design ensures that the valves and valve actuators ("fingers") are in constant contact as engine heat changes. The hydraulic lash adjusters make the valve train maintenance-free, saving the owner time and cost – there is no mechanical adjuster. This design realizes a reduction in undesirable valve train noise, especially on cold starts. This design maintains consistent pressure on the valve stem, which facilitates more- aggressive camshaft profiles, which can boost performance. Variable Valve Timing (VVT)* The Revolution Max 1250 engine is equipped with computer- controlled Variable Valve Timing (VVT) on both the intake and exhaust camshafts. Dual Spark Plugs The Revolution Max 1250 engine is equipped with two spark plugs per cylinder. Dual spark plugs improves ignition of the fuel charge across this wide-bore cylinder. The Revolution® Max 1250 engine is equipped with "dual side strap" spark plugs that are designed to better manage high temperatures in the combustion chambers than a standard spark plug. Dual Down-Draft Throttle Bodies* Separate throttle bodies are located between the cylinders, positioned to create minimal turbulence and impedance to airflow. Robust Oiling System* The engine oiling system is scaled to perform well in challenging conditions. Fully Balanced Powertrain* Internal balancers cancel most engine vibration to enhance rider comfort and improve vehicle durability. Clutch and Transmission* The Revolution® Max is a unitized powertrain, meaning that the engine and six-speed transmission are housed in a common case. * More details on the Revolution Max Engine can be found at the link below blue: Follow the Pan America story on social media at: https://www.instagram.com/hdpanamerica/ https://www.facebook.com/hdpanamerica About Harley-Davidson Harley-Davidson, Inc. is the parent company of Harley-Davidson Motor Company and Harley-Davidson Financial Services.
