I'm 62. (don't feel old though)
I've been somewhat obsessed with Royal Enfields ever since I saw an ad in Cycle World Magazine in 1968. I was 18 years old, and had yet to buy my first motorcycle.
The ad read "20 mph or 120 mph, have power to spare on a Royal Enfield". By then, the only model they sold in the US was the Interceptor.
There were other ads which called it the only factory customized motorcycle, and "the Rolls-Royce of motorcycles", a moniker which I was much later to learn belonged to the Brough-Superior.
3 years after I got my first motorcycle in 1969 (a Yamaha YDS3 Catalina 250), I had a chance to buy a basket case Interceptor.
In those days, there really weren't a lot of parts sources, even though there were many stashes of parts hidden away.. Things like seats, un-hacksawed fenders, mufflers, gas tanks, were hard to find. Engine parts, and tune-up parts were a phone call and a few days away though, so I kept mine running, even if it had a Triumph gas tank and forks, a custom Cobra seat, generic Dunlop fenders....
Hoping to come up with the right parts to restore my '66 Interceptor to original form, whenever one of these parts stashes turned up while I had money in my pocket, I bought them.
The funny thing was, there still weren't a lot of original fenderrs, gas tanks, seats, or other parts like that.
Thanks to Enfield India and companies like Hitchcock's and Burton's, reproduction original parts are now available if you have the money.
