Actually though, they are not a "rendition" of a 50s bike, they are a 50s bike. Enfield move the factory to India in the mid 50s and they have been hand making them there the same way, in the same factory, ever since. The bike was designed in 1938 as a 350, and upgraded to a 500 in the 50s. About the only major differences with the very new ones is Fuel Injection to meet pollution requirements, and an aluminium block instead of cast iron. With 76 years of production, the Bullet should be sorted out pretty well by now.
