For Solid State flashers I personally would like to recommend the Kisan Signal Minder;
https://www.kisantech.com/index.php?cat_id=4I have used on many bikes, and like HexCode, they are very responsive to making improvements, resolving issues, giving advice & tips.
Back at the topic at hand;
As already mentioned, I would like the new GS-911 to be such that I can leave it connected to the R1200RT and ride the bike to get some realtime values. I have had issues with the sensors failing only during higher temperature of the engine and so on.
Or an adapter/extension-cable would be good too.
And, not sure if mentioned or the place to state it;
It would also be great to have some trade-up programme, if possible.
Get some money back for the ol' & trusted GS-911.
