Goos Bos owns a motorcycle shop in Hengelo, in the east part of Holland. As a motorcycle freak he is specialized in building sidecars and sells production and customized bikes. On May 25 he organizes, for the second time, the Koning Zelfbouw Dag. ('Custom King Day'). Customized bikes will be shown and a 'Custom King' will be awarded with a trophy. For more info about this day and pics from the last edition, have a look at the blog.I will attend this day with an expo of my vintage motorcycle trading-cards albums, so that's an extra reason to show up!
