Synopsis

* 107ci with 114ci and 137ci variants in the development pipeline
* chain driven with single overhead camshaft with four valves per cylinder
* valves actuated by forked rockers meaning both intake and both exhaust valves have same duration.
* a big change for HD, no automatic hydraulic valve adjusters and no shims like modern Japanese bikes, adjustment is with nut and lock nut system, probably done to improve high RPM performance where hydraulic adjusters do not work so well. Will require manual adjust at the dealer every ~20K.
* 6000RPM redline
* air cooled with water and oil cooled heads
