But there’s a larger issue at work here. If you sell me a new bike and you expect me to do a 600 mile service, but then you can’t offer that service within 5 weeks of me buying the bike, then that’s just not a great customer experience.
I get your frustration and I agree re your experience point. An interesting aspect of service wait times is that if your service capacity equals your service demand, service wait times become infinite. So, service providers have to buy excess capacity if they want to maintain reasonable wait times. However, motorcycle service demand is seasonal, so they can size their service staff for the height of the riding season and pay for excess staff during off season or they can let wait times wax and wane seasonally. They cannot afford to pay for excess staff off season, so we all get wait times that wax and wane seasonally.
I can think of three solutions I've used to work with this. (1) When I'm buying a new bike during the busy season (rare for me), I make the break-in service appointment part of the negotiations so I have an appointment scheduled when I expect to need it before I write the check. (2) I used to live near Bob's BMW in Jesup, MD; they solved this problem by making Saturdays first-come-first-served. They painted numbers on the service area motorcycle parking spots; if you really needed something done that day, you arrived before they opened, or at least quite early on, and parked in the open spot with lowest number. These sessions became mini-rallies with riders bringing food, drinks, chairs, books, tall tales to swap, etc. Bob's did this in part because their service wait times grew to 4-6 weeks during the height of the season. Perhaps you can suggest something like this to your dealer. (3) I know how to do my own basic services; if I can't get in, I can at least make sure continued use of the bike doesn't put it at risk of mechanical failure or void my warranty (I fully document everything when I do a service).
Oh well, we live in an imperfect world; that's not going to change anytime soon; but somehow we mostly muddle our way through.
