How to identify the right model and parts
KYMCO Japan’s catalog identifies the pre-2015 Downtown 125i as SK25AA. That is a regional catalog designation useful for parts lookup, not proof that every 2014 scooter sold worldwide has the same specification. The title alone also does not establish ABS equipment or homologation.
Before ordering parts, compare the registration and frame label with the seller’s fitment information, and use the manual for the matching market and variant. KYMCO Japan directs owners to genuine-parts retailers or the dealer that sold the vehicle; the catalog does not establish current stock or prices. KYMCO Japan parts catalog.
