This exhaust is specifically designed to fit Yamaha Aerox 50 and 2 stroke Chinese made 50cc scooters such as VMOTO, Alien, CPI, MCI, Ikonic, Mojo and Benelli models. As all these scooters may have slightly different exhaust mounting, minor modification may have to be made in some cases.
When installing a performance exhaust it is necessary to increase the jet size in the carburetor. Failure to do so may result in engine damage. Transmission and clutch tuning may also be required to get the best performance out of this exhaust.
