A drive layout for an offroad vehicle. The vehicle has a frame, at least two wheels supporting the frame, and an internal combustion engine supported by the frame. The engine has at least one cylinder, a piston positioned in the cylinder and reciprocating along a first axis. The piston drives an output shaft of the engine which is arranged to drive at least one of the wheels through a transmission. The vehicle has a longitudinal centerline, with the output shaft of the engine extending transverse to the centerline. The transmission includes a main shaft driven by the output shaft by a belt extending along a second axis. The main shaft drives a drive shaft which extends parallel to the centerline and which is arranged to drive at least one of the wheels. The layout is arranged such that the first axis and second axis are positioned on opposite sides of the centerline.
A drive layout for an offroad vehicle having a frame, at least two wheels supporting said frame, an internal combustion engine supported by said frame, said engine having at least one cylinder, a piston positioned in said cylinder and reciprocating along a first axis, said piston driving an output shaft of said engine, said output shaft arranged to drive at least one of the wheels through said transmission, said vehicle having a longitudinal centerline, said output shaft of said engine extending transverse to said centerline, said transmission including a main shaft driven by said output shaft by a belt extending along a second axis, said main shaft driving a drive shaft, said drive shaft extending parallel to said centerline and arranged to drive said at least one of said wheels, said first axis and second axis positioned on opposite sides of said centerline.
A drive layout for a vehicle having a frame rollably supported by at least two wheels, said vehicle having a longitudinal centerline therethrough, an internal combustion engine having a body defining at least one cylinder, said engine supported by said frame, said cylinder having a central axis, a piston reciprocally mounted in said cylinder along said central axis, said piston connected to a crankshaft, said crankshaft extending transverse to said centerline and arranged to drive at least one of said wheels through a transmission, said transmission including a primary shaft driven by said crankshaft, a main shaft offset from said primary shaft and driven by said primary shaft by a flexible transmitter, said flexible transmitter extending along a flexible transmitter axis, said main shaft driving an output shaft, said output shaft driving at least one drive shaft arranged to drive said at least one of said wheels, said belt axis positioned on an opposite side of said centerline from said central axis.
