A one off Harley-Davidson Cross Bones motorcycle designed by artist Damien Hirst

Artist Damien Hirst has unveiled his latest masterpiece – a multicoloured, chrome-laden hog.

But his handiwork is a far cry from the formaldehyde suspended cattle he is best-known for, instead it is a fully-working 1,584cc, 75bhp Harley-Davidson chopper.

His colourful custom will be auctioned for a Los Angeles-based charity on April 23.

Working from his Gloucestershire studios, Hirst decorated the Harley-Davidson Cross Bones bike using his own 'spin-painting' technique.

The artist's unusual method involved pouring paint over the bike as it span around on a platform.

Hirst's multi-hued Harley is expected to fetch more than £70,000 in next week's Project Angel Food charity auction and bidding will open at £17,000.

The winning bidder will also receive two unique helmets designed by the artist.

Project Angel Food delivers more than 11,000 free meals to people battling Aids and cancer in Los Angeles every week.

Margaret Steele, the charity's CEO, said: "We've already had an unparalleled amount of interest from not only local bidders but many oversees art and Harley-Davidson enthusiasts.

"If the initial interest is anything to go by, the bidding for this unique bike could be very exciting."
