To provide a wheel fender flap that is less susceptible to swinging during the use thereof and capable of retaining an appealing feature, the wheel fender flap arranged to confront a vehicle wheel, includes a generally elongated flap body supported by a vehicle body structure and a reinforcement member separate from the flap body, but used to increase the rigidity of the flap body.

Vehicle wheel fender flap

Disclosed is a motorcycle having a cowling covering an under side thereof in which the cowling can be formed so as to avoid a catalyst while maintaining strength of the cowling, and can maintain a large bank angle and secure the minimum road clearance. The motorcycle is provided with a vehicle body provided with an engine, an exhaust pipe connected to the engine, a catalyst apparatus provided in the exhaust pipe and arranged under the engine, and the cowling covering at least an under portion of the vehicle body. An opening in which an entire peripheral edge portion thereof is formed in a closed hole shape is formed at a position of the cowling corresponding to the catalyst apparatus.

Motorcycle

To provide a rear wheel fender structure for motorcycles, which can be molded with a simplified and inexpensive mold assembly even where the rear wheel finder is so designed and so structured as to permit component parts to be fitted thereto and as to block the splashing of water and/or mud, the rear wheel fender structureis positioned above the motorcycle rear wheeland includes an upper fenderand a lower fendersecured to a bottom region of the upper fender. An adiabatic spaceis preferably formed between the upper fenderand the lower fender

Motorcycle rear fender structure

To provide a motorcycle exhaust system, which is less susceptible to the elevated temperature of the exhaust gases and vibrations induced by the motorcycle combustion engine (E) and in which the sectional area of the exhaust passage can be properly adjusted independence on the operating condition of the motorcycle combustion engine (E), the motorcycle exhaust system includes a motorcycle combustion engine (E) mounted at a location generally intermediate between front and rear wheels (and), an exhaust passage fluidly connected at one end with an exhaust port of the motorcycle combustion engine (E), a silencer () fluidly connected with the opposite end of the exhaust passage and supported by the motorcycle frame structure (FR) at a location generally above the rear wheel (); and an exhaust control valve () disposed in an inlet of the silencer () for variably adjusting the sectional area of the exhaust passage.
