Flat or dead battery? Is the charging circuit working properly?
Time for multimeter tests. |

£1400 for a 11+ year old 125? Vince Candelin special?
As above, spend £5 on a multimeter and diagnose, don't just start guessing.
Something else to try is shorting the starter solenoid terminals with an (insulated) screwdriver. If the starter spins then you've got power from the battery but a problem on the starter circuit, either the solenoid itself or the starter switch.
The dead headlight does suggest that the battery is borked though, although the good news is that if it runs OK after bump starting then your charging circuit may be OK.
But... multimeter. No guessing. ____________________ Biking is 1/20th as dangerous as horse riding.

OK, that's good news. It sounds (sight unseen) as though your battery is weak (or shorting internally under load). That it's running once started is hopeful.
Have you tried jump starting from a (engine off) car battery?
However, before you replace the battery, I would urge you to check the voltage with the engine off (should be ~12.5V, I expect it'll be lower), and with it running (should be 14-15V, but... Honda).
If the reg/rec is pumped (Honda...) then it might be over-voltage, and that's what's killed the battery. It'll kill another if you just replace it.
And now back to our scheduled BCF.

Dealers are certainly asking that for 3000 mile garage queens, and private sellers rave about them (while trying to offload them).

Well, on that we can agree. ____________________ Biking is 1/20th as dangerous as horse riding.

Starter relay / solenoid.
The two terminals he's fiddling with, bridge across them with an insulated screwdriver. They will spark, and you can get a small spot weld, so be prepared to yank it free. That will send voltage directly from your battery to the starter motor.
If it doesn't spin (and you don't have a blown fuse anywhere), then the problem is with the starter, engine earth or battery.
If it does spin strongly, then your problem is with the relay or the low tension wiring leading to it from the starter button.
This is really just the most basic thing you can check without a multimeter. With one, you can stop guessing and diagnose the problem in a few minutes. ____________________ Biking is 1/20th as dangerous as horse riding.
