The machine, a 500cc Corah built in 1910, will be shown in tribute to its previous owner, at the Motorbike Show at Llangollen's Royal International Pavilion, on August 2 and 3.
The bike was one of a large collection owned by enthusiast D
on Leeson, from Bryneglwys, near Corwen, who was killed while racing on the Isle of Man three years ago.
He was 57 when he died during the Isle of Man Grand Prix in September 2005. He had competed in the event seven times previously but lost control of his 400cc Honda on a bend.
Mr Leeson's interest in machines did not develop until relatively late in life but he soon became an accomplished rider, and also wrote authoritatively about the history of the sport and machines.
After his death his collection of 40-50 bikes was sold at auction at Kempton Park racecourse last year, and two of them were bought by his friend, Gareth Williams.
From Garth, near Froncysyllte, Gareth has had a lifelong interest in motorbikes and old cars.
One of the bikes he bought is a 250cc Suzuki on which Don Leeson raced and which still has his name on the fairing.
He was a founder member of the Vintage Japanese Motorcycle Club and an avid collector of Suzukis.
"I intend to take it to track days at Oulton Park and Ty Croes, Anglesey," said Gareth, who is most proud of the other bike, the Corah.
"I always told Don that I fancied having it and I was determined to get it in the auction."
Built in Birmingham, the machine is still in superb condition despite never having been restored.
"Don said it was the only one in the world, but I know that's tempting fate," said the retired electrician, aged 65.
It still has its original pedal-bike-style brake system and acetylene headlamp.
"There's no clutch and you have to pedal like hell to get it going," added Gareth, who plans to ride it next March in the annual Pioneer Run for pre-1915 models from London to Brighton.
In 1992, during the 75th anniversary celebrations of the Isle of Man TT, Frank Whiteway, who won the 500cc race in 1968, rode the Corah in the winners' parade.
Gareth is pleased that he will be able to display both bikes at the Motorbike Show, especially as the venue is so close to his own home and to his late friend's home.
"It's great that there's a show being held in this area. I don't know if it's true, but I've heard that there are more old British bikes in the Dee Valley than anywhere else, most of them kept hidden well away, so there'll probably be a lot of people going there," he said.
The Motorbike Show is being organised by David Green
whose Xuberance event management company already runs the town's Balloon Show, Gardening Show and Llangollen Food Festival.
David said: "We are absolutely delighted that we are able to provide a platform to display such a rare bike as a tribute to Don Leeson, who was something of a legend in motorcycling circles.
"It is a terrible shame that he died so tragically on the Isle of Man but we are pleased that we can help his memory live on.
"Not only is Llangollen close to where he lived but it is also a mecca for bikers with thousands and thousands of them coming to Llangollen and the nearby Horseshoe Pass.
"One thing that still amazes me is that we have so many leading motorbike figures who live in the Dee Valley."
David is keen to hear from anyone who would like to be involved as exhibitors or people wanting to show their bikes.
