Love them. Awesome. I ride a Triumph S4 and it is the modern rendition of the cafe racer. You could put clip ons on a Triumph S3 or just buy the Thruxton too. There is a French company that makes parts for the modern Bonnevilles that make them into amazing looking retro cafe bikes.
That is the best executed clubman/cafe racer to come from a factory in recent memory. A far better balanced design than the Triumph Thruxton. The fact that Terblanche designed it is even more surprising.
