They have good engineering and manufacturing, the issue is in their dealership supply network. Dealers have been forced to take bikes apart to get parts. Obviously, this new twin represents a huge investment, all in hopes of capturing some piece of the US and European bike market.
It's going to be interesting to see if they can pull it off.
After 20 years as a professional bike mechanic and 30 years as an engineer I know just enough to be dangerous !
There's a guy on Jay Leno's Garage who made a V-twin using the existing top ends off an RE Bullet. To build a nice twin cyl engine quickly, that to me seems like a safer way to go for several reasons. I would have canted the cylinders much further forward than he did, like the first Ducati twins, or the V-Strom... but that's just me. 180° and 360° vertical twins have so many inherent issues.
Heck, even a transverse BMW or Guzzi inspired twin, using the Bullet heads and cyls would have been safer. Ability to negotiate very narrow streets and parking spaces must have been an issue !
