The 1949 Triumph Trophy TR500 used by Fonzie, played by actor Henry Winkler, in the hit American TV show Happy Days is to be sold at auction later this month.
The bike will appear at Julien’s Auctions, Planet Hollywood, Los Angeles on Saturday, June 23 and is expected to fetch $100,000 - $200,000 (£75,000 - £150,000).
Winkler, who couldn’t actually ride a motorbike and for most of his scenes was simply sat stationary on the machine, used three Triumphs during filming as he reportedly found the first few too heavy.
Brando and Arnie's bikes also up for auction
Appearing alongside Fonzie’s bike will be a 1969 Harley-Davidson FLH Electra-Glide motorcycle owned by Marlon Brando, estimated to go for $150,000-$200,000 (£112,000 - £150,000) and a 1987 army green Harley Davidson FLSTC Heritage Softail Classic, with a colour matched half helmet and pair of leather gloves owned by Arnold Schwarzenegger, estimated auction price, $30,000-$50,000 (£22,000 - £37,000).
