They are pretty bikes . It appears that HD has added a liquid cooled componet to their "Rushmore series" sounds similar to the set up that BMW added to their aircooled RT lineup.* Update: Harley-Davidson has incorporated liquid-cooled cylinder heads in their Twin-Cooled High Output Twin Cam 103 engine (found in the 2014 Harley-Davidson Ultra Limited and Tri Glide Ultra) and the Screamin' Eagle Twin-Cooled Twin Cam 110 powerplant (in the CVO limited). The system hides two radiators in the fairing just aft of the rider's legs, and routes water hoses into the tops of the cylinder to primarily cool the exhaust valves.
I would give the Indians a year or two to make sure they stick around and hoe they do.They are ice looking bikes for sure.
