You should always specify the model, either FSC600A (antilock brakes) or FSC600D ( non-antilock) as well as the year of your scooter for parts and service requests here. Luckily for you, the air cleaner is the same for all models and years. The part you want is 17230-MCT-000, priced at $28.40, here:
