A diamond-encrusted motorbike designed by Wayne Rooney has fetched £43,250 in a charity auction, £13,000 less than estimated.

The Manchester United player customised a 2012 Lauge Jensen cruiser-style machine with 21 black diamonds and one white diamond.

The motorbike normally retails for £56,000 and auction house Bonham predicted motorbike would sell for between £40,000 and £60,000.

The footballer, who could have attempted a more eye-catching design, chose instead to modestly place the diamonds in the shift rod.

To complete the unique bike an autographed No 10 football shirt was lacquer-sealed onto the petrol tank.

When he was asked to support the auction, Rooney said the design of the bike was inspired from the celebration of his overhead kick against Manchester City in the 2011 season.

Danish firm Lauge Jensen, a bespoke v-twin-engined motorcycle manufacturer, described the motorcycle as a "truly unique" machine.

The money raised from the sale will support KidsAid's work in Denmark with sick youngsters.

Bonham's auction house in Chester said the motorcycle was sold to an anonymous bidder.

Other popular items at the auction included a Brazil shirt worn by Pele which fetched £3,500.

A collection of 22 Premier League inaugural season hand-signed and match-worn shirts was sold for £18,750.

Two silver-gilt Heavyweight Lonsdale Belts won by Henry Cooper, one in 1965 and 1967 and another used in 1962, 1963 and 1964, each fetched £12,500.
