An extremely rare racing motorcycle from the 1920s that lapped the famous Brooklands race circuit at over 100 mph is expected to spark a bidding war at the Bonhams Autumn Stafford Sale in the UK this October.

One of only two of its kind known to survive, the 1929 Grindlay-Peerless-JAP 500cc “Hundred Model,” estimated at up to about $100,000, won the Brooklands “Gold Star” award in 1937.

Grindlay-Peerless rider CWG “Bill” Lacey became the first man to cover 100 miles in an hour on British soil in August 1928.

Not half bad for a claim to fame…
