I wonder if they still feel the same about that statement with all the problems they are having with this motor? I realize there are a lot of people with no issues, but there are far too many that are experiencing issues especially with the oil migration. Part of me is hoping for M8 in the softails, and part of me is hoping they leave the twin cam alone. I really don't think you'll see it in the 2018 Softail because obviously it will not fit in the frame, and if they have to make any adjustments at all there has to be a patent, and one is not been applied for from what I can find out.
I bet we'll see the M8 in either the dyna or the softail lines for 2018. Maybe even both.

A Softail has it's engine solid mounted and the transmission mounted to engine but the swing arm is part of the frame.
The pre M8 Cruisers and Dynas have the Engine hung by rubber, the transmission mounted to the engine and the swing arm mounted to the transmission.
So, in reality, the rear wheel, transmission, and engine are a unit hanging off the frame.
Where is the swing arm attached to on the M8?

maybe some bright engineer will make it so you have to take the rear wheel, fender AND seat off to make room to put a very special shaped wrench on the shock for adjustment
