I've seen a few "spy shot" pictures of these machines, I reported an article myself, in the Himalayan section of the forum, back in the beginning of April.
But I'm starting to wonder WHY folks are calling this a "Himalayan", since it seems to have nothing in common with those machines?
In fact, I'm wondering if it is even from Royal Enfield at all? I haven't seen manufacturer badges showing in any of the pictures, and all the body work seems to be covered. As far as I've seen, it hasn't been spotted riding in company with other, more identifiable RE developmental prototypes either.
How do we know this isn't a Suzuki or a Honda? Has RE made any official declarations that these prototypes are part of a project they are working on? Was there announcement of a water cooled engine project, perhaps from the tech center in Leicestershire, or outsourced elsewhere?
