The XRM 110 has undergone changes. A 2002 catalogue will not show parts for a 2018 DSX model. Look for the model code inside the PDF (e.g., KZR, KZZ, or NF). Match it with your VIN plate.
Walk into any Honda dealer’s parts counter with the PDF open on your phone. Show them the and the diagram reference . This eliminates language barriers and guessing.
Many old catalogues are just image scans. You cannot search for a part number with Ctrl+F . Use an OCR (Optical Character Recognition) tool like Adobe Acrobat Pro or online OCR converters to make the text searchable.
These are harder to find. Try CMSNL.com – they archive microfiche for vintage Hondas. Also, check PhilMoto (Philippine motorcycle history groups).
