Original Piaggio spare part which is of much better quality than the replicas. Very elastic and at the places where it engages in the carburettor sump or the frame reinforced with a stable bead. The intake hose should be checked occasionally for its condition. If it should show cracks or be porous, the engine will draw in false air faster than you would like. This can lead to a lean mixture and can cause serious engine damage. AI-translation
