A unique collection of BMW motorcycles will be up for auction at Bonhams' Las Vegas Motorcycle Sale in January.
The group of four is headlined by a rare 1939 Kompressor RS 255, which is the same model used by iconic motorsports racer John Surtees. The rider described the bike as being among the top machines to ever race in a motorcycle grand prix, with an authentic 1930s engine mounted on a 1951 frame - something that was common in the early days of factory racing.
Three other BMWs are also going up for auction - a 1954 RS 254, a 1954 RS 254 with a sidecar and a 1956 RS 256. The price tag for these motorcycles is expected to reach six figures each, as similar bikes have brought in more than $130,000 at previous sales.
"Competition BMWs, particularly those from before and just after WWII, are increasingly gaining interest from discerning collectors," said Nick Smith, head of Bonhams USA. "They were highly advanced, extremely well-made, and successful, and this combination of attributes makes them tremendously desirable."
This will be the third annual motorcycle sale for Bonhams. In addition to classic bikes, the auction features memorabilia, motorcycle gear and accessories.
