I am thinking of a starting a long term project (not a quick respray and back on the road in 3 weeks). Two bikes have me interested, both very different but by the same maker, either a boxer or a K series BMW. I know the boxer has been around forever and has loyal following. Are there any major advantages of one over the other (reliability, parts, ease of maintenance etc)? I have seen many examples of the boxer as a project bike for personalisation but very few for the K series. In some ways this makes lean towards the K. Any opinions?
