I see from the old catalogs that the Suntour GPX brake levers supposedly have adjustable reach. I peeled back the hoods but didn't see any accessible screws or bolts that might adjust the reach.
I didn't remove the bar tape to look more closely.
Any idea how this was done? If memory serves some older brake levers could be "adjusted" with shims, but I'd rather not bother with that if it's what Suntour meant by adjustable.
