Harley's never impressed me, my son rides a Heritage Softail. Besides the cost to buy and the cost to maintain, there is the reliability Also a Softail requires the oil tank and filter change plus a purging process requiring removing lines and cranking the engine. Then there is the transmission. Just my observation.
Neither Softails, Dynas, Touring or Sportsters require a purging procedure. As per the service manual, warm it up, drain it, change the filter, plug it, fill it, ride it. Many Softail owners choose to purge the system, but it is totally unnecessary, and not indicated. Those that do it will argue the point, and if it helps you sleep nights.... but most Softail owners don't do it, dealers and service shops don't do it, Harley does not indicate it. Constant removal of the hard lines will eventually create leaks that will necessitate their own repair. Not worth the trouble IMO.
Spike you might be right on Honda not helping trip breakdowns. When leaving the motel in the morning, three times in the last 6 long trips, a Harley rider was being left behind while he was waiting for someone to pick up his bike. I felt bad for him as his party pulled away.
Last year when I was filling up a HD rider pulled in filled up and asked me to give him a push when he was going to pull out. His clutch cable failed and it was hard to take off shifting into first. I understood his problem and helped him.
Clearly you are not convinced re: Harley reliability. It's okay, many don't get it, few that don't have ever owned one. I've had mine 2012 RGU since 2014. It has never seen the shop since I've bought it. I've never had any issues requiring repair, beyond normal service. My Honda, OTOH, needed a few parts replaced along with the regular maintenance. Leaky radiator, coolant hoses, fuel pressure regulator, clutch due to weak springs. I will add in one valve adjustment which the Harley does not require. Yes I did all of the work on my own, and enjoyed it, but beyond adding new things to the Harley and regular lubrication and hydraulics flushing, it's all about the ride.
Remember that for many years, Harley sold more bikes in the US than all other bike manufacturers put together. Ergo, odds are that if a bike breaks down, it is, by the laws of probability, more likely to be a Harley than any other single brand. That, and, have you ever noticed how many old Harleys are being ridden? Shovels, Evos and carbed TCs are still common. As these bikes age they are, like any mechanical system, more likely to fail. And, it has been a personal observance that many Harley owners do not know how to prepare for a long trip. That and they fail to see the small "quirks" that creep in as potential system failure points. Like, "It always starts if I choke it, let it crank 3 times and let it sit for 10 seconds, open the throttle and crank it. Never fails." Yeah, never fails until it does. Might be far better to make it so that it starts reliably without a non-standard ritual. And, sometimes things (sensors) just fail. It happens. Harley is rated among the 5 top bike manufacturers for reliability. As I recall, Yamaha is the best. BMW, Triumph, CanAm OTOH are rated among the worst!
