The secret collection of amazing classics that may or may not be for sale - content

There's no address on the website, satnav doesn't take you to the exact location, and when you do find it, there's no visible signage until you're feet from the seriously serious-looking security gate entrance to a forecourt in front of an anonymous industrial unit that could be anywhere. Automotive journalist Iain Macauley explores the topic further. 

Cameras abound and equally-serious-looking metal barriers protect the perimeter and reinforced metal shutter-type doors. 

The only thing I'm allowed to say about it is that it's in the North West of England. 

Why the security and secrecy? 

The bike at the top of the stairs to the upper level is a clue - a £225,000 Brough Superior; but then there's the sucker punch: the one next to it cost £350,000... 

Solo Motorcycles is a collection of amongst the very best that many motorcycle manufacturers have ever produced - around 300 bikes. They've been amassed by businessman Steve Malone, 65, and are as much a collection for his own interest as they are for sale. Maybe for sale. You get the feeling most of them might take some prizing out of his possession. 

Pre-war British bikes are, to be tactful, flat-lining or falling in value, so when Steve and Solo's business consultant Robert Bentham, 66, point out a Norton which has been sold for a very meaty five-figure sum, in the process bucking the trend, you know that's a special one. 

"When they made this one, a Norton International, they took all the good bits upstairs at the factory and put it together, and everything is stamped with the same number. It's definitely matching numbers," he said. Details of value and buyer aren't shared.... 

Instead it's a tour of the two-floor showroom and display areas. The only windows are skylights, quality lighting emphasising the colours, chrome and condition of the bikes. 

And what a collection. 

The first bike you come across on the ground floor is a 1968 Egri Vincent 1300. 

"Look at that, it's a work of art," says Steve. "In fact this place is full of works of art. Every time you look at some of these bikes you see a new detail," he adds. 

Adds Robert: "When I open up in the mornings, I just laugh out loud when I switch the lights on; I can barely believe, as a bike enthusiast, what I'm walking into. 

"Every bike has a story. Some have big stories, others are just interesting for all sorts of reasons." 

Adds Steve: "We've got a Levis from 1916. It was parked up by the owner soon after it was bought. Makes you think: with that date on it, did somebody go off to war and not come back....? 

"It's in 'first paint'," he said, a reference to what one of their friends said about a 1970s Montesa off-road bike which had clearly lived a life: seat stitched up, but the plastic of the seat itself polished to near mirror finish by sheer usage. But, overall, completely original - in other words "in first paint". 

Bent Spanish number plate suggested it may have gone end-over-end at some stage, original-looking dirt, dust, dents and scars giving it a patina and character only hard use can suggest. 

In the next row are two late '90s Honda CB50s, one a road bike, one a racer, but each with 14,000rpm red lines. The road bike has just two "push miles" on the clock, while the racer has even been started. 

Next to them is a '70s Honda "scrambler", an SL350. In a typically period shade of green it's testament to Steve's view that classic bikes should be ridden: so into the van it went as they headed off to the Isle of Man for August's Classic TT where it did a lap of the mountain and was his runaround for the duration of the event. 

"Never missed a beat, absolutely brilliant," he said. 

Solo Motorcycles is a secret sea of desirable machinery, from BSA Bantams up to Steve's KTM Paris-Dakar bike: yes, he competed in and completed the epic in 2007. 

In between are BMWs, Ducatis, Harley Davidsons, Indians, all the Japanese brands, an array of British historics, and machines you'd be hard pressed to identify, going back nearly 120 years. 

Steve's favourite: a 1929 Husqvarna. 

"The classic bike market has had a 'correction', bikes are now worth maybe 60% of the prices paid by collectors during the pandemic, but niche bikes - like the Husqvarna - are maybe bucking that trend," he said. 

"But that means they are so much more affordable: my message is buy them and ride them." 

All I need to do now is to persuade Steve I'd be open to the "ride them" bit - my excuse for not buying them being the old standby: I can't fit any more in my garage...
