30yo boomer in UK, tall, just passed my CBT. I'd like to ride around on L plates for at least a few months to get a feel for riding, develop good habits.
I'm poor and don't own a bike yet. I have decent, full gear.

I'm mechanically competent and have my own tools. I have worked on engines before, but not bikes.

I want a Varadero 125 but the ones I see advertised below £1500 are rusted out shitters. That's still the - medium term - aim.

To reiterate - I'm completely fucking skint atm for reasons, so is there some ancient piece of shit I can pick up for under a grand to dick around on and work on in the meantime?

Any recommendations?
