Personally, I'd rather have the cable,Why you ask?
1. Cables only snap when they are not maintained, meaning yearly, ya got to lube the cable, if you don't, yes! it can snap. With hydraulics, No adjustment...
2. I can adjust any clutch with the cable for the way I want it to grab, Hydraulics, either it's in or out, no slipping, if needed...
3. When travelling afar, if my cable should break, with a spare or new one I can fix, Hydraulic clutch fluid go out, your done, call a tow truck... Expensive fix cause now it has to be bled.
With that being said, Yeah hydraulics may be the forward move but the machines are getting to be that you must take back to the dealer to repair, just like the cars. And as I get older, changes even though may be a better thing, I'm starting to buck... I've always enjoyed through my winter months to go over every aspect of my bike to be mechanically ready for the season. This way you get to know your bike
Oh my cable, has over 65,000 trouble free miles on it as well as the rest of the bike, (my 2011 tour glide ultra), and still works like new...
Anything mechanical in time can and will fatigue, do scheduled maintenance to keep her running like a kitten
