Given three decades of motorcycle development it would be odd if things were otherwise. Don't know if they intend to use the engine in some other models, it probably has a bit of tuning potential. A few detail lines on the engine cases don't look quite right, down to their existence as styling themes rather than emanating from mere functionality but overall it's not a bad rendition of retro style. Again, absurdly, the pistons move up and down together, requiring a hefty amount of counterbalancing to get rid of the resultant huge quantity of primary vibration. Honda sussed this in 1965, with their 180 degree crank CB450, and Suzuki more or less perfected the design in the GR650 Tempter.
Modern engineering has no such constraints.
Top gear rolls-ons were not particularly impressive, though power delivery was linear without any hiccups. 60-100mph cruising and total apathy on the gearbox you could just about get away with, but the bike was rather more spirited in the fourth of its five gears. Top speed was an indicated 115mph, when it has to be said that only the most biased of owners would complement the engine on the level of vibes it gave out, although most of the time it was as smooth as the much more powerful TDM850. Torque wasn't on a scale that would impress 883 Sportster owners' but made for generally easy riding. A modern classic it isn't.
