The Rear Cylinder Deactivation is "seemless" on my Roadmaster. Idles smoothly on one or two. But there is a control for it. You can turn it off in your "Settings" if you want to do without it.Go for it, i rode my challenger 300 miles today, no problems but the rear cylinder deactivate drives me crazy!!!! will tell the dealer to get rid of that "feature"
I live in FLORIDA. I ride in triple digit heat some times. It's a definite help.
@sonny the big Roadmaster is a blast to ride in the mountains (or pretty much anywhere there's a decent road).
It can even handle 2-up on a not so decent dirt road (how bout it @TheKid ?)
