I've seen a few of the Royal Enfield thumpers around Denton and Austin. They do sound rather British, with just a slight Sub-Continent accent.
This retro bike niche market continues to grow.
300 of the 1,100 Steve McQueen Triumph Bonneville SE tribute bikes -in matte green- are due in the US by June of this year. Plus, the Tri Thruxton is a popular model. Moto Guzzi has released a beautiful 750 retro cafe. Perhaps BMW Motorrad will reintroduce the Airhead? Ah, dream on, Klingon.

Royal Enfield Cafe Racer
While all phases of the proposed bike have yet to be completed, Enfield Dealer Developer Ron Greene believes it will be well-received and estimates Royal Enfield will import 100 examples to U.S. in its introductory year. He believes the bike will cost from $7,995 to $8,495. “They’re always developments and constant changes going on. We won’t know what our café racer model will finally look like until we pry open the crate.”
