It doesn’t take a rocket scientist to know there are only a few commonalities between nautical craft and bikes. Infact the one factor they have a tendency to have in widespread are the supplies used to construct them. One materials that doesn’t usually bridge the hole between boats and bikes is wooden, however that’s to not say it by no means occurs. Occasionally a customized motorbike pops up on my radar that has wooden utilized in its building, and when it’s achieved proper the outcomes may be extraordinary.
Fifty 4 12 months outdated carpenter Jacques Jouvin is aware of a factor or two about working with wooden. Based mostly in Avignon, France his Atelier JAB workshop produces premium cabinetry for native clientele. When Jacques isn’t constructing cabinetry, he likes to work on bikes and sidecars. And a few years in the past he determined to merge his ardour for picket hulled watercraft together with his love of bikes.
The Atelier JAB XS650 was impressed by luxurious runabouts like these produced by Chris Craft and Riva.
“My private imaginative and prescient is {that a} motorbike should have a line; refined, elegant and racy. I make monohulls and picket assemblies utilizing methods from the nautical world,” says Jacques. “For this realization, all the things was fastidiously thought out. “I began on the lookout for a base that had marked its time, specifically the Yamaha XS650. I discovered its traces, components and engine very adaptable to customization.”
After buying a 1978 Yamaha XS650 Jacques pulled collectively a staff of fellow bike fanatics to understand his imaginative and prescient. The group consisted of Fabien Tourlan, in any other case often called “l’Atelier Les Bécanes”, who specialises in classic motorbike restoration, Aymeric Romanowski of Atelier WIK and Bernard Christy, who deal in components, and David Gallet Dadygraph and Laurent Chapus of Neway Designs for the paint.
“The preliminary thought was to construct a monocoque with a really fluid line paying homage to the American and Italian luxurious sports activities boats of the 20s and 30s,” Jacques recollects. “For the overall line of the machine, I needed a café racer that blended metal with aluminium and wooden.”
As soon as the XS had been dismantled Jacques modified the body. Together with eradicating any nonessential brackets, the chassis was bolstered and modified in preparation for its new bodywork. Templates have been then made to get the scale and proportions locked in and as soon as he was joyful, Jacques set to work constructing the Yamaha’s picket monocoque ‘hull’.
With such a novel undertaking the selection of timber needed to be as distinctive as its utility. After wanting via his assortment, Jacques picked out a uncommon and endangered wooden referred to as Wengé from the Millettia Laurentii tree in Africa. “It was discovered within the house of a retired fellow woodworker who owned a secure lot since 1976,” he tells us.
Remodeling the uncooked timber into bodywork match for a useful motorbike was no meant feat. Taking some 10 months to finish, Jacques used a number of completely different woodworking methods to understand it. The Wengé boards have been joined collectively previous to shaping and aluminium has been added to the construction for extra energy and sturdiness. To showcase the attractive grain of the Wengé wooden to the identical premium degree as the luxurious boats that impressed it, it has been coated in 12 layers of UV-resistant varnish. A bespoke brown leather-based saddle and traditional Monza filler cap full the development.
The creation of this Yamaha cafe racer went effectively past the development of simply the bodywork. The XS650 is now operating a customized wiring harness that includes an up to date CDI. The rear flip alerts use LEDs put in into the body rails behind repurposed orange methacrylate from a set of Nineteen Seventies door handles. The battery is housed in its personal field beneath the swingarm pivot and the entire electrical cables run out of sight.
After its modification, the body was additionally cleaned to easy out the manufacturing unit welds, sandblasted after which powder coated utilizing a chrome look end. The forks have been shaved and polished and a customized drum brake help added. The rebuilt triple timber use a customized prime yoke and the fork internals are upgraded utilizing progressive springs and hydraulic adjusters. The rear suspension is all new consisting of a pair of 320mm retro-look Hagon shocks. The wheels are polished Akront Morad rims with stainless spokes and the entrance fender doubles as a fork brace.
Jacques additionally utilised a number of off-the-shelf parts to finish his cafe racer. There are E.NOV clip-ons fitted with chrome-plated aluminium handlebars, Tommaselli Matador brake and clutch levers, Rizoma bar finish flip alerts and hand-turned picket grips. A single Motogadget ChronoClassic gauge takes satisfaction in place within the cockpit and it sits in a customized wooden and aluminium encompass.

“We modified the entire gearbox bearings, rebuilt the cylinder head (new seats and valves), rebored the cylinders, match new pistons, bolstered the oil pump, put in an digital ignition, suppressed the kickstart and match a brand new clutch with bolstered springs.”
Together with the motor’s improved reliability, it’s been given a lift in efficiency utilizing Keihin PWK 34 carburettors, aluminium intakes, a whole stainless exhaust system and Okay&N air filters completed with Wengé wooden. Lastly, the cylinders have been completed in satin black and the entire instances polished to a mirror end.
Typically used as recreation crafts for the wealthy and well-known, Chris Craft and Riva runabouts are the epitome of aquatic luxurious. The Atelier JAB XS650 is a bona fide homage to these watercraft. Constructed to exacting requirements and from uncommon, premium supplies, it’s a one-of-a-kind motorbike that may look proper at house in a personal assortment, which is the place it’s probably destined.
