Honda has said as much haven't they? They ARE going to release special Crf rallye bolt on parts. If this eventuates, it's a major strategic improvement compared to the xr600 where Honda really left its development and enhancement to the aftermarket (as well as crazies like me who convert them to estart sleds with fcrs and usds).
I've mistaken the Crf rallye if what you say is true. I see the Crf rallye as far more obtainium than a one off ktm rallye.
I think it will go like this:
Rmhrc buys his ADR spec base sled crf450x. Then he buys rallye shop parts which are largely bolt on to suit his application (s) Backed up by the supply chain of the worlds largest motorcycle manufacturer.
The difference between my xr experience and now is HRC will clip the ticket on more parts. They will also fit far easier and more cleanly.
