I think it has 'honest lines,' the design is purposeful and is built for longevity, not for minimum weight. If it could come to USA market for that $3K, I think they could sell a bunch.
The 411 cc cylinder with undersquare dimensions (78 x 86 mm) relies on a simple layout with a single overhead camshaft and two valves, is fed via a carburetor with throttle position sensor, and produces some 24.5 hp that are driven towards the rear wheel through a five-speed gearbox.
If they could get the engine to make an honest 40 RWHP without compromising longevity, I think the bike would be very well-accepted here. The 24.5 HP figure I expect is their crankshaft figure, which probably means about 19 RWHP which is what a 1963 VW 'Bug' had. Maybe asking to double the RWHP is a bit much to ask. There have been people who modded the old Bullet to achieve some respectable HP #'s. Fritz Egli I think was one, but his cost doubled the price of the bike, I think. http://www.carolenash.com/insidebik.../56-miscellaneous/742-egli-bullet-clubman-535
This Egli below is based on the 'new' engine developed a few years ago, but is not the smaller displacement 'newest' R.E. engine. I think a wrecked John Bloor-era Bonneville engine would look very good in this chassis! Dunno if it would fit.
I didn't watch the video, I suppose this has some-sort of a counterbalance driven off the crankshaft? Honda did very well for many years w/their parallel-twins, I wonder if they tried different configurations, or if they just decided to go w/a single, a very 'undersquare' one at that?
