The top 5 motorcycles at Bonhams’ den Hartogh Collection Auction


Most motorcycle enthusiasts would consider 50 two-wheelers to be the pinnacle of ownership. But in the Piet den Hartogh Collection and Museum in Hillegom, Netherlands, just outside of Amsterdam, the sizeable motorcycle collection is an afterthought. Bonhams will auction off the bikes on June 23, a footnote to the real show stoppers—200 immaculately restored Fords, thought to make up the world’s largest single collection of Ford automobiles, which will also cross the block that day.

BMW and Harley folks always seem to be willing to pay premium money for their brand of choice. The Sarolea seems like a steal, basically a pre-war motorcycle, nice little vintage cruiser, accepted at most every show, Well bought as they say.
