Abstract

A motorcycle frame is cast in two parts which are bolted together along the longitudinal centerline of the motorcycle. The frame has a transverse section in the form of an inverted 'U', the space defined by the 'U' being arranged to receive a motorcycle engine. An upper wall provides a separating partition between a fuel tank and the engine for defining a longitudinal space of reduced transverse sectional area towards the rear of the frame.
