Congrats on you're bike! BMW cycles use a boxer as well ya know. Its a fine engine design for a cycle since the pistons firing outward provide for unmatched handling and balance. I just rode one of the new big Bimmer 1200s. It was amazing. So balanced, so comfortable. Would definately be a great bike. It it wouldn't require trading in 3 or 4 SVXs to get.
As with most boxer engines the seals are an issue. Other than that you have a bullet-proof engine that should/could go well over 100k with basic upkeep. I'd prefer a Triumph Bonneville for a cycle and have managed to keep myself out of the dealership so far this year since I don't have the cash for another toy but I do admit I keep checking the paper for a cheap old Bimmer.
