Maybe you got a lemon?
Having owned both hondas and beemers, I can say that I was more impressed with the BMW. That said, I owned an R bike, known more for their reliability that the K series, and more popular in terms of sales. Of all the bikes that I have owned, including a Triumph, Suzuki, Buell (shudder), HD along with the other two, I miss my R1100S the most. It was the most versatile, comfortable and reliable bike that I have ever owned.
I had no problems chewing through tires, clutches or oil. I didn't baby the bike, as I used to ride the canyons of Nothern CA with a bunch of buddies on R1s, blades and GSXRs, having no trouble keeping up with them in the twisties and being much more comfortable doing it. Yes, BMW luggage is expensive, but I managed to get the dealer to throw it in for free (tank and saddle). It is still the best luggage I have come across, hands down. It made the bike great for long trips without beating me up along the way, allowing me to have fun once I got there.
Yes, some parts are pricier for the BMW than the Honda, but that is the same for cars as well. No one said that the BMW was the most practical of all bikes, but it is one of the only brands with a 100k club. There is a reason for that
