Relax or Race.

With the Clubman Racer from 46Works.

An evening spin off into the mountains and a Sunday afternoon out on the race track – the Japanese Shiro Nakajima had specific ideas of what he wanted to do with his R nineT conversion. With the Clubman Racer, he created an all-rounder entirely according to his own taste. And nevertheless meets the taste of the scene.

Self-realisation in the province

His reputation preceded him. Shiro Nakajima had long-since made a name for himself as a musician, before he first set foot in the customizing world. With the Label Ritmo Sereno, he opened a shop in Tokyo for European custom bikes and converted primarily classic BMW motorcycles. In 2014, Shiro moved from the city with a million inhabitants into the interior of Japan and set up a new shop on the foothills of the Yatsugatake mountain range: 46Works. Four in Japanese is shi, six is ro. Apart from custom bikes, the qualified engineer made parts for classic cars and furniture. In his free time, he can be found in the Yatsugatake mountains just as often as he can in vintage races. Shiro's focus clearly lies on craftsmanship. In Yatsugatake, he finds the peace and quiet he needs to create motorcycles that have just as much deceleration in their DNA as they do performance.

Whether I make music or motorcycles – my mindset is always the same. For both, fantasies become real. ’

Shiro Nakajima


With the Clubman Racer, Shiro worked on a new BMW Motorrad for the first time. The bike emerged as part of the R9T Japan project, whereby four renowned Japanese customizers each converted an R nineT. Specifications: none. The perfect pre-requisites to give the bike its own stamp off the rack. "It was my first international contract. I travelled a great deal and met some very interesting people from the scene. It was very exciting", Shiro proudly recounts. His signature becomes very clear for the light, functional bike. The aluminium bodywork is completely made by hand. The line of the rear is reminiscent of the style of classic racing machines. Shiro understands how to combine performance with striking details and in so doing creating the perfect balance between relaxing and racing.
