I'm surprised that nobody has mentioned this yet...
...the engine on this has been de-tuned down to 48HP. I've read elsewhere that this will meet a new Euro-restriction on certain moto-licenses.
I'm wondering how the tuning was done? If the G650 engine is mostly intact from the X-challenge days then maybe it would be a simple FI map change at the dealer to put it back to 52+HP...?
