Lionel Duke builds a little bit of everything. His Nice, France-based custom shop, Duke Motorcycles, has transformed Honda Goldwings, Kawasaki ER6s, and Ducati Scramblers into unique one-off creations in recent years. But the most interesting thing to come from his garage actually isn?t a bike at all?it’s a box full of parts.
More specifically, a box full of parts to convert any stock BMW R NineT into a radical-looking plug-and-play custom streetfighter. It was this very kit that caught the eye of Duke?s latest client, who saw a picture of Lionel?s prototype build online and decided he wanted one for himself.

The client loved the original kit’s supercar-inspired design, but wanted a few unique touches of their own to truly make it theirs. And Lionel was more than happy to oblige. ?He had been asking around Parisian workshops that offered their own R nineT kits,? he says, ?but none of them were willing to modify their standard parts to suit his tastes. I told him that it wasn?t a problem for me, as I actually prefer to do different things on each project.?

After a little back and forth, the final brief landed somewhere between a streetfighter and a muscle car, infused with a number of café racer– and scrambler-inspired touches. Many of the core pieces of the kit were kept in the mix. Lionel fabricated and fitted the kit’s generous fiberglass belly pan lower down, and a stylish Alcantara saddle up top.
This one-off adaptation also retained Duke?...
