Headed by French engineer Cedric Klein, Avinton Motorcycles specialises in made-to-order muscle bikes. For this particular Avinton model, customers could choose from six different specifications and three alternative riding positions; it is highly unlikely that there are two bikes exactly identical. Our vendor selected the Collector GT version, which has a slightly higher handlebar position for comfort, and opted for the highest specification for all other components. He was invited to the factory in France to check on the build's progress.

Avinton's Collector GT is powered by an American-built 1,647cc S&S Super Stock v-twin engine producing 120bhp and 123ft/lb of torque. Belt primary drive transmits the power via an Evolution clutch to an Andrews five-speed cassette gearbox. The engine is a stressed member of the large-diameter tubular frame. There is a bespoke aluminium alloy swinging arm, while the suspension is courtesy of Öhlins at both ends; the steering damper likewise comes from the famous Swedish firm. Beringer six-piston callipers grip the twin floating front brake discs, while there is a single disc with four-pot calliper at the rear. The Avinton rolls on Marchesini Racing forged alloy wheels, finished in gold.

Built to the vendor's specifications in 2017, the Avinton bristles with special features: the 'tank' does not contain any fuel (the reservoir is in the tail section behind the seat), while the oil is contained within the frame. Hand made, the exhaust system combines carbon fibre and stainless steel, and carbon fibre is also used for both mudguards. All other fittings are either made by hand or selected from the world's foremost components suppliers.

Offered for sale by the original owner, this stunning creation has covered fewer than 1,000 miles since it left the factory and is presented in commensurately good condition, barely run-in. Not surprisingly, the owner reports that the bike never fails to draw a crowd. Very few were made, and it's pretty much guaranteed you'll never park next to another one.

Accompanying documentation consists of V5C Registration Certificate and a folder of information including photographs of the Avinton under construction; original sales catalogues; the original build sheet/invoice itemising the specification; and instruction books for the Öhlins suspension and the installed BikeTrac alarm/tracker. A once-in-a-lifetime opportunity.
