If it is your first ever motorcycle, then... no, don't. Really.
If you really like the look of bikes from the 1950's and 60's, get one of the modern bikes that shares that look. Triumph's Bonneville has to be a top choice, otherwise it's the Kawasaki W650, although the Bonneville is a better bike.
The Enfield isn't so much a modern bike styled to look like a 1950's clunker as a genuine 1950's klunker with the barest minimum of updates applied over the last 50 years to allow it to still be sold.
It's horrible to ride, unless you are on a masochistic nostalgia trip, slow and gutless in the extreme, bits will vibrate themselves loose and fall off if you do long trips on it or fail to go round it tightening everything up once a week. The brakes barely work by modern standards, the gearbox redefines klunky, etc etc.
It's also a heavy pig to manage.
So do yourself a favour. Don't!
