Siamkijkarnyon.Co.Ltd (YAMAHA Square)
4/6-8 Rama I Rd, Rong Mueang, Pathum Wan, Bangkok 10330
Siamkijkarnyon, trading as YAMAHA Square, is an authorised Yamaha motorcycle dealer in Bangkok handling sales, servicing, and parts for the brand's range. The shop covers the everyday side of motorcycle ownership, from buying a new machine to scheduled maintenance and spares. As a brand-authorised point rather than an independent workshop, it gives riders warranty-backed servicing. It functions as a full sales-and-service Yamaha outlet for commuters and riders in its part of the city who prefer dealer support over a roadside garage.
