To answer the question about my BMW F800GT. It was a 2016 model and had 31,000 miles on it when it broke. Generally a very reliable bike (with a dull engine). Bought it used in mid 2018 with 4,700 miles and purchased a 3 year unlimited mileage service contract with it for $1,500. Dealer did all the service work on it including changing the drive belt at the 24,000 mile service. I thought it was too tight and called and left a message about it but didn't get a response. Left on a 5,500 mile trip. Had the 30,000 mile service done days before I left. Dealer wanted to work on the clutch and pointed out a weep from the water pump but not belt comment. Left on my trip and bearing failed 1,100 miles later. Warranty ran out in April or May of this year. I do not think BMWs are inherently unreliable but dealer service can vary tremendously between dealerships. Will have to say the technician did a good job adjusting the clutch. They were concerned about it not shifting smoothly and hard to find neutral. Told them not to worry it was always that way - in fact I had even asked about it at least once when dropping it off for service. When the oil was fresh and the engine hot it could be very difficult to find neutral but got better as the oil aged. IMO if the belt had been properly adjusted I would not have broken down but had a great adventure and got a bike I like better.
Edit: I would not hesitate to buy another BMW if there was one I really liked or wanted. Their bike are well thought thru and well finished and generally reliable. Just watch out for the German mindset - we designed it properly you need to adjust yourself to our properly designed motorcycle. Would have service done differently though.
Since Ive retired have been doing long road trips with all my friends - that would be me! For that I need a reliable bike that I can get parts for. For fun rides that are closer to home I think an exotic bike would be nice - would drive me crazy having to cancel a trip just because something broke and I couldn't get a part - oh wait I just did that
31k miles and only one hiccup doesnt sound bad for any bike manufacturer to me! I'm looking forward to the BMW demo event in two weekends. Not even because I necessarily plan on getting one, but just to get a feel for the different offerings and riding styles on the market. The S1000R, The R Nine-T and one of the adventure bikes are on my list to try.
