Looking at the wiring diagram, the 1050 has 2 extra pins compared to the 650.
I have one of those adapter cables, it has a full compliment of 6 pins (that I presume are wired to the OBD connector). It may just be worth trying as they are probably standardised and it just means that it exposes another/other networks (I believe CAN as it shows a twisted pair going to the mode connector) for the tool to talk to.
The 650 uses KWP from my understanding, there is no CAN on my bike.
