A Rider, Not a Collector

Billy Joel has never been shy about his love of motorcycles. Over the decades he amassed more than a hundred of them — not to display behind glass, but to ride. "I was not a collector," he told The Hollywood Reporter. "I was actually a rider."

That identity is now being tested. His doctors have made clear he can no longer get on a bike. They have also barred him from the stage. A rare brain disorder has reshaped almost every corner of the life he built.

What Normal Pressure Hydrocephalus Does to the Body

Joel went public with his diagnosis of normal pressure hydrocephalus in May 2025, canceling all of his scheduled concerts at that time, Today reported. The condition develops when cerebrospinal fluid accumulates inside the brain's ventricles, pressing on surrounding tissue and disrupting balance, vision, hearing, and memory.

It is most common in adults over 65 and is sometimes reversible with early treatment, ABC7 New York reports. The standard surgical approach involves implanting a shunt to drain the excess fluid. Joel underwent that procedure and told listeners on SiriusXM's The Billy Joel Channel that it genuinely helped. "I had a surgery, and they implanted a shunt in my brain — and it actually improved things," Reality Tea reported him saying.

What His Neurologist Told Him About Performing

The surgery improved some symptoms, but it did not clear Joel to return to work. His physicians connected years of high-volume performing directly to the progression of his condition. Each show, they explained, was inflicting concussion-like trauma on his brain, AXS reports.

"What the neurologist told me, every time you do a show, it's like you're getting a concussion," Joel said in his interview with The Hollywood Reporter. The combination of extreme sound volume, lighting, physical stress, and energy output all factored into that warning.

He cannot say whether a return is possible. "I have to take a series of tests before I know," he told the publication.

Saying Goodbye to More Than 70 Bikes

With riding off the table, Joel made a decision about his collection. More than 70 motorcycles will go under the hammer without reserve at the Gooding Christie's Rétromobile New York auction at the Javits Center, Billboard reports. A preview of select bikes was on display at Christie's Rockefeller Center ahead of the sale.

The lineup spans decades of motorcycling history. Forbes reports the roster includes machines from Ducati, BMW, Moto Guzzi, Harley-Davidson, Yamaha, Triumph, Honda, and Kawasaki. A restored 1975 Ducati 750 Sport carries a pre-sale estimate of $25,000 to $35,000.

The crown jewel may be a custom 1978 Triumph Bonneville T140 that Madison Square Garden presented to Joel to mark his 150th sold-out performance at the venue. The bike comes with a matching helmet inscribed with the date of every one of those shows, Hagerty reports.

The Proceeds Go Somewhere That Matters

Joel is not simply liquidating a collection. Every dollar raised at the auction will go to the Joel Foundation, his nonprofit dedicated to music education, Wide Open Country reports. The organization supports school recording studios and music therapy programs.

He was direct about his reasons for letting go. "I'm into my 70s now, and I realized I can't ride as much as I used to," he said. "I don't want to die like a bug on a windshield."

The bikes were always meant to move. Now they will — just under someone else's hands. Whether Joel himself will move again, toward a stage and a piano, is a question only the next round of tests can answer.
