They still make Royal Enfields in India. There's a Royal Enfield dealer in the next small town over from
me. The owner is an enthusiast and and seems to like motorcycles that are less technically advanced
than a brick

... He thought the Valkyrie had cooties or something

I'd say that a 2008 Royal Enfield is
not collectible, and that if you think it is cool (for some
definitions of "cool", it is cool) you can get new ones cheap...
