It's a foxeye model, so both bulbs are supposed to be illuminated at the same time for dipped and main beam.
Since the flash works I've ruled out the bulbs for now.
Foxeye models use 2 H4 bulbs. The high/beam elements are in the same bulb so it's possible the low beam elements have blown but not the high. It's rare but I've seen it so check the bulbs first. Falling that check the fuses and that there's power to the switch, both sides. If there is power in but not out it's the switch, corrosion, broken, earthed etc. If theres no power in or out it's the wiring you need to check, same if power out.

That's interesting, thanks. I would have thought in that scenario the LHS low-to-high switch would still work. But I guess a resistor detects the dipped bulbs have blown so then can't pass power to the highs.
