I mentioned one here in Veracruz that was only dealer maintained, ran premium fuel here, and every bearing in the motor was finished and BMW replaced the motor but the owner paid for dismounting the old one and mounting the new one. The motor was supposedly sent to Germany for further study. As a side note, the owner of that bike had replaced every other bearing on the bike, front wheel, steering head, and rear wheel and all were bad and some with catastrophic failure that resulted in the bike being trucked home from one trip. It was an early 2009 build date with some differences from other 2009 models like the front brake master cylinder being a cloudy plastic finish and the rear axle left side being a different arrangement. That bike never detonated that I know of and just was worn out after 30,000kms of dealer service.
