Prompted by a question in this month's e-zine, I'm posting an update to this thread, just for completeness.

Frank found, after much waiting and wringing of hands, that the Norwegians wouldn't issue him with a carnet. Or, more specifically, that the Dutch ANWB (who were investigating the Norwegians on his behalf) stopped communicating with him. Therefore I do no know of any automobile association that will issue a carnet for an Indian-bought, Indian-registered bike.

However, if you're willing to take the risk of being turned back, you could try the journey back to Europe without a carnet, as I am currently doing. So far made it as far as Turkey, which means I'm into territory where a carnet isn't required. More details on the financial and administrative pain this involved in the blog at

As for registering a bike in your own name in India, this is not necessary if you're not going to take it out of India. If you do need it in your name, I can only give definite information about one dealer who can do this: Madaan Motors in Karol Bagh, Delhi. Of course, it's not officially permitted, but the resulting registration documents weren't questioned on exit from India. I was very surprised just now (having spent close to two months in their workshop!) that they have a flashy website:

Note that some people reckon that Arun Madaan is a crook, whereas others say he's a good man. I'd tend towards the latter view, and charitably maintain that my current serious bike problems aren't his fault! There may well be many other dealers in Delhi and elsewhere who can perform a similar service with respect to registration.

There is a thriving trade in second-hand Enfields, both between travellers and back to dealers. Some dealers operate a buy-back scheme, whereby they will undertake to buy the machine back at a specified price in the future - can work out much cheaper than renting, but naturally you have to beware of being screwed. One man who would never screw you (but makes you pay for the privilege) is Lalli Singh of Inder Motors, Karol Bagh.

Hope that's helpful for anyone thinking of taking this classic bike on a classic route, which has sadly become so much more difficult recently.
