AFAIC, the wannabe Harley Jap bikes don't even factor into this arena. Despite the fact that they'll run forever like everything else the Japanese build, what possibly would motivate someone to rock one of those bikes is beyond me. Could be price, reliability... no idea. Let's be honest, most factory bikes are pretty reliable these days. They don't even really sell those wannabes in Japan. They're dedicated to the western markets, primarily America. This is because of one principle consideration by the manufacturers… esthetics. Personally, I've never even entertained the idea of owning one. You want a Harley, save your milk money and buy a Harley. Same-same a Brit bike, sport bike, or whatever. Yet the Japanese prevail.
Speaking of esthetics- compared to the "bikes of yore," all motorcycles fall a bit flat esthetically these days. There's simply no comparison between most modern bikes vs their ancestors. For Christ sake just look at a vintage Speed Twin compared to a modern one. Apples and oranges. You can't even make an argument, and I for one think the modern Speed Twin is a landmark bike for the age. With the looming death of the Sportster, the modern T100 and T120 Bonnevilles are about the best examples of attention to purity in pretty much any example of westerm motorcycle currently on the rode, with a BMW or two hot on their tail.
If you're a legit vintage Triumph rider these days you're in a class of your own. It's a different landscape out there. I get it that it must be a bit frustrating to see so many of the old school particulars like tank badges and whatnot get sidelined, but at this point it's just business. Be thankful there's still a Triumph and keep in mind that the Triumph that built your bike is not the same Triumph that builds the Street Twin or the Rocket, and this current Triumph has struggled mightily to acheive what they have so far. The fact that Enfield and BSA have stood up, in my opinion, in response to Triumph kicking so much ass after near extinction speaks volumes. Hopefully these companies will grow and maybe those little attentions to detail will become a competitive factor. It's not beyond the realm of possibility… "the more things change, the more they stay the same." These modern "Brit" bikes are living proof of that adage.
Cross your fingers.
