I presently have a 2016 Africa Twin, a 2012 KTM 690R enduro, a 1998 Ducati 900SS and a 2017 Vespa. I have also recently owned a Yam WR250R I bought with 1200 miles on it and a 2004 KTM950Adv since new. I ride my Ducati the least so it is mostly a garage queen. But a very pretty one. I rode my KTM950 for 7 years and about 70k miles. Almost all of it on long trips. I'm coming up on 20k miles for the 690 and about 15k miles for the AT (most of that is coast/coast trips too). For me the most important thing are confidence and comfort. Neither of my KTMs inspired much confidence but I made them comfortable. One of the comfort features I adopted was quality earplugs so I didn't have to listen to that KTM motor. Seriously! Neither of my KTM motors sound like finished products. They make all kinds of metal/metal noises such as cam chain clatter and other valve gear part noise. Plus they vibrate and warn you when they are working too hard (probably not, but that is what it sounds like). The Honda AT works like a well-tuned watch. The motor seems perfect to me. It runs effortlessly at 90 so that you don't even know you have crept up there. The Yamaha was another vibe-free motorcycle. Its motor is solid even when running out of speed at the throttle stop while climbing some pass in the Rockies. Just downshift and the speed comes back. Happens again in 5th, just go to 4th. It is like magic. The speed comes back. My oldest son claims I cheaped out when I bought the Honda. I was supposed to buy a new water pumper GS like his. And he is right, that the price difference was too much to ignore for me. So at this point I have to say that I think the Japanese products are better consumer products, but the Euro models have enough special character that I enjoy them the most despite their imperfections. I just completed the 2018 Alcan5000 aboard my 690. I found a tech who was able to finally make that motor run properly after all these years of owning it. At 320lbs, she was a lot more enjoyable that my AT would have been. Not as smooth, but still made the challenge more fun in my mind. Regarding service intervals, I'm not picky about that. As an example, my KTM required an oil/filter change during the Alcan (over 6000 miles once completed). I merely replaced the old oil at 4k miles and skipped the filters. Not really a great idea but it better met the task at hand.
