While there is a styling similarity to the Diavel rear end the bike is hardly a copy or clone. There’s at least a dozen Japanese bikes with similar treatment - look up CB1000R for one. The Diavel looks far more like that butt ugly Yamaha a few pages back than it looks like this new Rocket. In fact this Rocket, overall, looks nothing like a Diavel, just a similar rear. There’s only so many ways to tidy up a rear end so it’s inevitable there’ll be more than 1 manufacturer taking each approach.
