Horex VR6 Patent Includes W8 Configuration
Horex VR6 Patent Includes W8 Configuration
The VR6 Roadster uses two a 1218cc triple overhead camshaft engine with two offset rows of three cylinders at a 15 degree angle. The engine configuration allows the engine to be compact enough for a motorcycle (Horex says it is slightly wider than a conventional inline-four but also slightly shorter).
A U.S. patent registered to Clemens Neese, founder of the revived Horex, for the VR configuration also allows for two VR setups to share the same crankshaft in a W arrangement up to 12 cylinders. Like the VR configuration, W engines are used by automaker Volkswagen with examples including the 2001 VW Passat and the 2011 Audi A8.
Illustrations show a W8 engine mounted longitudinally on a motorcycle with the cylinders pointing outward like on a Moto Guzzi. The diagram is an example of a 1500cc W8 with a 60.6mm bore and 65mm stroke. The engine is comprised of two 15-degree V-inline banks joined in at a 72 degree angle.
A Horex W8 isnt likely to emerge any time soon however, as the VR6 Roadster wont enter production until later this year.
