The Bistella 500cc may just be the only custom on the planet that could make Allen Millyard scratch his head – a supercharged 10-cylinder two-stroke radial.

Czech engineer Marek Foltis is the brains behind the creation which uses a 1953 Czech-built Jawa 18 as the base model. The main goal, says Marek, was to: “Create my own engine design, something that had never been used before in any vehicle.”

As has been said before...just 'cos you can doesn't mean you should

OK, I give up. What is/was it?

Love the Curlywurly exhaust and the headlight that looks like it came off a theatre lighting rig. LOL at the front wheel/tyre.

I really don't know! Guessing a scoot of some description?

It's the helmet on the seat which gets me.

Bike looks mad, but then you see that Helmet and realise it must be tiny. Or it's owned by this guy.

There's something Suzuki about it. That cylinder does suggest scooter. Shame we can't see the other side. If it's a single then it's a very scootery engine but the tank suggest some sort of Frankenstein hybrid...or a damn fine Photoshop.

PS You're right Dazzle, if that helmet is to scale it's tiny.

Honda Grom?

Google image search suggests Navi.

Cracked it Hoss.

It's not a Navi!

The Navi has a storage box where the engine is!

It's a (heavily customised) first generation MSX125, known by the Septics as a Grom.

I did suggest a Grom but none of the images I found were first gen.

If I'd bothered scrolling further ...

When a goldwing just isn't big enough

Quite a contrast between the before an after pics...

Retrospective: The history of Elf motorcycles

Rétrospective : L’histoire des motos Elf - Paddock GP (paddock-gp.com)
https://www.paddock-gp.com/retrospectiv ... motos-elf/

In nearly 75 years of Grand Prix, there have been many attempts to stand out. The France is not to be outdone when it comes to the most unusual experiments, and a slew of engineers from France have tried, successfully or not, to modify the design of a motorcycle. This is the case of André de Cortanze and Elf. A unique epic that smells of the 1980s.

De Cortanze was not short of work in the late 1970s. A graduate of INSA, then hired by Renault to develop F2 and F3, he is undoubtedly one of the most promising brains of his generation. He became project manager at the Régie in 1977, and focused on the newly designed turbocharged Formula 1, partly developed thanks to the expertise of the late Jean-Pierre Jabouille, who had just left us.

At the same time, Elf, a major French oil company, is very present in the world of motorsport, and features prominently on the body of the Renault RS-01. Elf does not neglect the motorcycle world, which leads to the birth of a common idea: Why not try to produce an innovative machine, and above all, competitive?

De Cortanze, passionate about two-wheelers, is on the spot, accompanied by the cartoonist Daniel Trema. He can only note the lack of innovation in the motorcycle world, compared to Formula 1 which had changed a lot since the 1950s. The fork and tubular frames were principles of another time, which, according to him, were largely outdated. In February 1978, a UFO appeared: the Elf X.
