Royal Enfield is a high maintenance bike - I'm talking about the previous model with cast iron engine and pre-war technology. You'll love riding it. Only problem is reliability. Now that, Bullets are so common, the value has come down. Newer Bullets with UCE also have their own quirks.
The thing is, this is a different breed unlike Indo-Japanese bikes with high reliability and cheap to maintain. Bullets like AJS/Matchless, Norton's, BSA's are primitive in their build, but gives a very comfortable ride. People here often look for old model (Cast Iron engine) with "heavy crank" so as to cruise in 30-40kmph with that bassy thump(Phad Phad) which is really likeable. Bullet mechanics are in great demand especially for modifications. A motorcycle suitable for the men in the 30's and above.
