The motorcycle ridden by Henry Winkler's character in Happy Days is set to go under the hammer.
The 1949 Triumph Trophy Tr5 made a number of appearances with Winkler as The Fonz in the hit TV show, but has not been ridden since the series came to an end in 1984.
It was originally supplied to the show by Hollywood stuntman Bud Ekins, Steve MCQueen's body double who completed the famous motorcycle jump over a barbed wire fence in 1963 movie The Great Escape.
Nick Smith, of auctioneers Bonhams, says, "This is the coolest motorbike ever - you would be hard pushed to find a cooler one. The two things that represent The Fonz are his black leather jacket and his bike... It would be quite something if you could say that you owned Fonzie's motorbike."
The auction will place in Los Angeles on 12 November (11).
