A Pre-war bike that’s in tatters and listed as ‘project bike’ that goes for nearly $500,000 is considerably more impressive than a pristine sportscar earning the same price tag.

Cars always grab the spotlight when it comes to record-breaking auctions. Marques like Ferrari, Mercedes and Aston Martin are always in the headlines with seven- or eight-figure sale prices next to the model names. But what about motorcycles? A pre-war bike that’s in tatters and listed as ‘project bike’ that goes for over $300,000 is in many ways even more impressive than any factory-fresh sports car earning the same price tag.
GoCompare.com worked with Bonhams to determine official valuations of the most valuable motorcycles in the world. The bike in the top spot has appreciated 4475.23% since it was new in 1951 — when it cost just $710.
Ben Walker, International Director for Bonhams collectors’ motorcycle department, put it best: “it is fascinating to see how the values have increased since the machines were new. Knowing what we know now – the percentage increase in value and how difficult it is to acquire these machines – it would be great to step back in time and buy them when new.”
