The Wing, or Honda has the biggest ace up its sleeve. BMW can't even touch this ace. and thats reliability, inexpensive parts and service when it does need to be fixed. Go and take you Beemer for electrical work or some oil leak some place. Sorry about your luck. That relay or module is $600 and $600 to install and guess what, we can't get it, and we don't have the tools to take the thing apart. Honda? go to you power sport store and order. And every tech can fix them, not to many specialty tools required. BMW all specialty tools. From that perspective I would avoid BMW like the plague. And did you know BMW is recalling 150,000 bikes for major front end failures?
Yep I'm aware that according to the internet forums I should have had several major failures on the various BMWs I've ridden over 20 odd years - surely I'd have had at least one final drive failure or switchgear failure! But alas no - nothing, nada, zip, zilch - fuel 'em and ride 'em, drop 'em in for tyres and servicing. I don't dispute there are problems and recalls but I've only had one new or nearly new bike let me down recently; my CVO Street Glide (switchgear - wouldn't start).
As far as speciality tools are concerned you're surely aware that the rest of the world has moved to metric - so I had to buy a bunch of new tools to work on my HD.... I probably have the essentials in my garage for any routine servicing of a BMW, add a GS-911 diagnostic tool and I could do a bunch more including fluid change on the linked ABS.
Dealer servicing costs have not been vastly different between my BMWs and my Harleys.
As I said, I'm still disappointed, I was hoping for more and think the new wing (on paper) doesn't stack up well to the K1600. They are so very similar in spec but the K1600 trounces the Wing everywhere it matters.
I will take one out for a spin when they're available for demo - but I doubt it will result in a sale for Honda unless the riding position is superb and the engine sublime and the price competitive - so still a possibility...
