Front view of a Silver 1985 BMW K100RS.

My 1985 K100RS – It ain’t pretty but still runs like a champ after 33 years.

At 129,000+ miles, still of full pep & punch. It has been as far west as New Mexico and as far east as the Polish-Belarus border. And here is proof that I am a knucklehead- I have kept detailed track of all the maintenance for the past 20 years.
