ABSTRACT:
A motorcycle exhaust pipe arrangement includes a frame having a head pipe, a main pipe, a down tube, at least one under pipe and a pair of center pipes. A fuel tank is operatively connected to the main pipe. An engine is mounted on the at least one under pipe and is disposed beneath the fuel tank. A seat is mounted adjacent said fuel tank and is disposed above the engine. A rear shock absorber is operatively mounted between the seat and the at least one under pipe for absorbing shock supplied to the seat. The rear shock absorber is centrally disposed relative to a longitudinal axis of the motorcycle. An exhaust pipe is connected to the engine and extends rearwardly therefrom, the exhaust pipe is disposed substantially at a midpoint of the rear shock absorber and extends substantially horizontally therefrom in the longitudinal direction of the motorcycle for lowering the center of gravity of the motorcycle and providing a symmetrical rigid frame for supporting the engine, fuel tank and seat.
