I have owned a 2003 Bullet 500cc. You can find 350cc ones in Europe. I would say that this bike would be a poor choice for your intentions.
"Royal Enfield. Untainted by technology"
The standard pre-2010 Bullet is essentially a new 1955 British motorcycle but with awful Indian metallurgy & still has the British random electrical gremlins. Seriously the bolt threads seem to be made of peanut butter.
The Electra model w/ the aluminum engine is a bit better & has a front disc brake. Yes, the standard has drum bakes. You will have to do regular, frequent maintenance & carry some spare parts.
These are made for secondary roads @ 55mph or less.
For your purpose, I'd recommend an older (70's or 80"s) Japanese bike.
