Bonhams Summer Sale in Bicester

Due to be held over three days, from August 14 to 16, the Bonhams Motorcycle Department’s Summer Sale will take place in the incredible surroundings of Bicester Heritage, Oxfordshire.

The lots will be on view in the 50,000sq ft former RAF bomber station hangar at Bicester Heritage, with pre-sale viewing on August 13 and 14 by appointment only.

The sale features more than 580 lots, with a sale of spares and memorabilia (including the vast array of parts, components and ephemera from the Morbidelli Collection) on Friday, August 14.


The motorcycles from the Morbidelli Collection, which had initially been lined up for auction at the Spring Stafford Show, will be offered on Sunday, August 16.

This four-cylinder Ducati, as built in 1965 and of a mere 125cc, will be under the hammer and sure to attract plenty of interest.

One of the highlights of the sale is an ultra-rare 1975 Suzuki 750cc XR11 Formula 750, as ridden to victory in the 1976 Isle of Man Classic TT by Texaco Heron Team Suzuki works rider, John Williams. Known as the ‘flexi-flyer’, thanks to frame tubes that were somewhat too small in diameter for the design and power that the engine made, this 1975 model XR11 has an estimate of £42,000-48,000.

The sale will be a live ‘behind-closed-doors’ auction.


The auctioneer will be present on the rostrum as usual, and bids will be accepted in the following formats: online, on the phone, or by leaving an absentee bid.

This 1920 Rudge Multi TT, of 499cc capacity, will also appear at the Bicester Heritage auction.

All bidding will be conducted remotely via a live stream online and in accordance with the latest government guidelines.

Pre-sale viewing of all lots is by appointment only.


Live and interactive video condition reports and enhanced online ‘walk around video’ content will be available for bidders.

And, incidentally, around 75% of the lots are being offered without reserve…
