The OE tire sizes for the Honda CT125 Hunter Cub (Trail 125) (2020–present) are 80/90-17 front and rear. Below are tires in these sizes, compared across brands. OE rim widths are F1.60 / R1.60 (from official specs; used for the rim-width check). OE sizes can differ by model year and market — the sidewall of your own bike is the sure reference. This is a Japanese-market lineup; the sizes themselves are international.

Front + rear set: 3 models can cover both ends (matching sizes in bold, based on F=80/90-17 / R=80/90-17). Shop links search on the model name alone. “Narrower” means one or two steps below the OE size. “Rim width OK” means the tire maker’s published rim widths line up with the OE rim width. No badge means we could not confirm it; combinations we found to be wrong are left out entirely.
