An early, high torque ensures the powerful cruiser torque: The 1802 ccm twin-cylinder boxer engine of the R 18 Classic is the boxer with the most displacement we have ever built. An engine you can see, hear, and feel: It delivers its maximum torque of 158 Nm at 3.000 min-1. From 2.000 to 4.000 min-1, it always delivers over 150 Nm, meaning a consistently high torque with the typical running characteristics of a boxer. At 4.750 min-1, the Big Boxer delivers 67 kW (91 hp). Start every tour with some zip.
