There is no denying BMW build quality. As soon as I first saw the K12, I knew it had been the subject of many many hours of carefully though out design. The look devides opinions as they say, but I believe a belly pan fitted as standard, would be enough to turn the tide for those who would declare it is not pleasing to the eye.
The K12 is not a light bike, but its weight is carried low, so the only time its noticable, is when you try to walk it backward up a hill (yes my garage is on a bit of a hill!).
The engine is responsive and linear, but if you want to see what the bike can do, you must relieve yourself of any mechanical sympathy you may have, as the K12's 4 pot makes the strangest noises I have experienced from a bike, especially when winding on from low revs. The K12 is a very fast bike, but it never really feels it. The ESP suspension, with its para - duolever set up works wonderfully well. The rear swing arm is also a marvel, single sided with a shaft drive, in a slim and sculpted arm keeping it all together, how do they do it?! The front wont dive like normal forks, and with ESP set up being WP units and braided lines all round, you wont ever want to upgrade these parts.
ABS is good for resale value, but not so good for riding. Sure it could save you someday.. possibly... but for the rest of the time its just awkward. Don't get me wrong, the brakes are good and stop the bike very well. At national limit speeds they offer all you need in power and 'feel'. But enter a town riding environment and they become snatchy and over sensitive up front, and have a dead feel too the rear. I believe it is due to the servo's assisting the brakes. But then if ABS were not installed, I'm sure the situation would swith on its head, and the brakes would be great round town, and awful for higher speed. The choice is yours...
The K12 is comfortable and can tour or scratch easily, why buy its ugly sister (the K1200S), when you could have a mean looking naked, and still be comfortable at speed. I would recommend the bike, it will serve owners well, and it will always devide opinion, making it the subject of attention at almost any bike gathering.
