FXER 103ci Shinken

FXER 103ci Shinken


In Japan, Shinken is an authentic Katana knife finely sharpened and often used as a weapon! It also happens to be the namesake of an old endearing dream by Gilles Sliwinski of Milwaukee Twin Metz and Bertrand Dubet of Odyssey Motorcycles Toulouse to design and rebuild one of those Monterey Class racers.

Gilles and Bert also happen to be with Jeff Duval, the founder members of the JETS Forever fraternity, which also goes a long way towards explaining that common visceral desire to resuscitate Old Flames; in Shinken’s case… Stricto Sensu.

Due to the extreme complexity of the project (amidst other more mundane priorities…) it took several years to finish the scoot.


As just an example, Bert had to cut the FXE frame in two to be able to lodge the Japanese Keiji Kawakita’s (Hot Dock) cam cover mods to the 103ci Shovel motor. And that’s only one example amongst many other custom applications.

Custom Exhaust

In fact, almost every part in this project was custom designed, stamped, welded or milled; an incredible challenge and outstanding result if ever there was one… That’s what Bert does in his spare time from his otherwise overwhelming duties at the Brough Superior factory 20 km from Toulouse in glorious Southern France.


Meanwhile, “Shinken” will now proudly reside in Gilles’ Milwaukee Twin Harley Metz emporium in Eastern France amongst many other yesteryear iconic machines. Honni Soit Qui Mal y Pensent…
