Does the c model have plug top coils or 2 coil packs like the b model ?
Scratch that, I just found out c's have plug top coils..which is good news
HM, Annitori etc
ie. stand alone quickshifters that plug in between the coils and the loom all should work.
Just a matter of find a mfg that has a loom for your bike.
I have an Annitori QS on the 10 which works as it should and the app to adjust it via my phone & bluetooth is a much simpler way of doing it compared to the old setup I had previously which worked thru the power commander.
