This is all very good to hear!
And, truthfully, as this is a new engine design, and isn't hindered by 60 year old designs and production, it should be good. There's no reason for it not to be good.
In fact, it HAS to be good, and basically be as good as anything from any modern competitors, for it to survive.
There's no more "crutch" of "antiquity" to lean on. That's gone.
So it has to stand as a modern engine, and those are the standards by which it will be judged.
By the sound of the initial reports, it would appear that they might actually have done it.
I have mixed feelings about the whole thing.
I like the fact that they have moved into the modern category, and are keeping the marque alive, with a "retro" type product that can appeal more to today's general public's needs. That was important for the company's survival.
I'm a little "misty-eyed" that the old Bullet is no longer going to be with us, because that was the last real remaining link to the heritage of the glory days of British motorcycling.
I sincerely hope that the factory provides good quantity and quality of parts for the older Bullets for many years to come. The old Bullet industry is a niche market unto itself, and needs to be properly serviced to keep the classics alive.
