Abstract

A smoothing plate (52), on the downstream side of an air inlet port (51a) on the upper rear streamlining (51), causes air circulation along the streamlining internal surface due to vehicle displacement. The air can be used for cooling the exhaust pipe and the electrical equipment. The air admission duct (18a) for the air cleaner (18) opens towards the streamlining internal surface and inlet dust is prevented. The fresh air, not affected by the engine heat, can be led into the air cleaner to ensure excellent engine output performance. The streamlining comprises a removable under-streamlining (46) in the part covering the carburettor and the air purifier. Through the exhaust ports (46a) in the under-streamlining, the clogging up of the air cleaner can be verified and the maintenance of the carburettor and air cleaner easily realised.
