Custom bike with prototype of new BMW Motorrad boxer engine wows Japan

On Sunday, December 2, Japanese motorcycle customising specialist Custom Works Zon presented a fascinating custom model commissioned by BMW Motorrad. The centrepiece of the machine is the prototype of a completely new boxer engine.

There was a lot of speculation at the show about the prototype engine. The external geometry and visible elements such as the push rods running above the cylinders in chrome-plated protection ducts recall BMW Motorrad boxer engines that were built until the late 1960s – but with an evidently larger capacity and a modern air/oil cooling. BMW Motorrad says further details about the engine and its possible future use will be communicated at a later point in time.

Custom Works Zon was founded by Yuichi Yoshizawa and Yoshikazu Ueda in the prefecture of Shiga in 2003 and is well-known for its exceptional creations. The custom builders are regularly invited to well-known shows in the customiser scene such as 'Mama Tried Show' in Milwaukee, 'The Hand Built Motorcycle Show' in Austin and the 'Brooklyn Invitational'. The small workshop has won a number if prizes and awards, clear evidence of the builders’ skill, craftsmanship and distinctive style.

Yuichi Yoshizawa was thrilled to collaborate with BMW Motorrad: “It was a great honour and a challenge to be able to build a motorcycle around the prototype of such a spectacular new boxer engine for one of the most tradition-steeped manufacturers.”

Zon's distinctive style can be clearly recognized: classic styling, modern production techniques and a wealth of craftsmanship in the detail – all produced to very highest Japanese quality standards. The very low silhouette of the bike is reminiscent of Ernst Henne's record-breaking machines of the late 1920s and 1930s. The large 21 front and 26-rear inch wheels are milled of aluminium and fitted with relatively narrow tyres, while the girder fork was also made of solid aluminium. The rear swinging arm is made of steel pipe and attached to the tubular space frame by means of concealed suspension. The large-volume engine is suspended in this frame structure reinforced with grid tubes. Meanwhile the fitted fuel tank, seat unit and front trim are crafted by hand from sheet metal.

This custom bike by Custom Works Zon in collaboration with BMW Motorrad bagged the prestigious  'Best of Show Motorcycle' award which is regarded the highest honour at this year’s Hot Rod Custom Show.

The Mooneyes Show – as it is known in the customiser circuit – was being held for the 27thtime in Yokohama, Japan. It attracts at least 15,000 spectators every year despite the fact it lasts only one day. Car and motorcycle custom builders from all over the world present their creations, with a total of nearly 300 cars and 650 motorcycles and there are also numerous dealer stands
