Instrument Time: A Yamaha SR500 constructed by a machine software firm




There’s nothing unfamiliar about setting up a customized motorbike with the foremost motive of taking it to a diploma to. Nonetheless what if the extent to in quiz has fully nothing to elevate out with customized bikes? That’s a frosty twist.

This sharply styled Yamaha SR500 flat tracker is the pet mission of 27-one year-ragged Maxime Fontvielle. He’s an software program program engineer on the French operation of the US machine software program program agency, Hurco—a profession he purchased into due to a love of two wheelers.




“Once I develop into as soon as a teen,” he tells us, “I alter into as soon as passionate about mopeds. Whereas taking a survey on the boards, I seen people making components for aggressive 90s mopeds and I believed, that’s what I need to elevate out! I went the entire talent in with apprenticeships at fully totally different companies, then I arrived at Hurco.”

Maxime stumbled upon a wrecked Yamaha SR500 for true €100, and had a mental perception: rebuild it as a showpiece for his agency, to expend to machine trade swap exhibits.




“Each individual 12 months on the swap exhibits,” he says, “the entire producers stage to their current machines in movement with conventional components from the aviation trade, and heaps others. I believed it lacked a exiguous passion and soul.”

“I needed to assemble an very sincere appropriate looking bike with machined components on it. I proposed to my boss that I put together this bike as an proper flat track beast. American self-discipline, American agency… proper here’s a match!”




Maxime’s boss correctly gave the OK—however there develop into as soon as a real three-month cut-off date sooner than the subsequent stage to. So Maxime decided to divide and overcome. He entrusted the engine rebuild to the Parisian workshop Machines et Moteurs, with a terribly express pointers, whereas he centered on the chassis.

The motor got here help with a 540 cc gear and a heck of various inner fettling. Highlights comprise an upgraded camshaft, improved oil journey alongside with the dawdle, a Mikuni TMR36 carb and a Okay&N filter. There’s moreover a model current header and reverse cone megaphone muffler, every from SC Problem in Italy.




Maxime’s first job on the chassis develop into as soon as to put in a 19” rear wheel to check the doorway. He ended up sourcing a second SR unit, and machining it to expend a sprocket and a 300 mm brake disc. Then he machined customized wheel axles, tailor-made the doorway to elope with larger bearings, and lightened every wheels by ‘splitting’ the spokes.

There’s no brake on the doorway, however there’s a Brembo caliper and grasp cylinder out help, linked by a braided stainless steel line. Since Maxime develop into as soon as upgrading the bike from a rear drum brake, your full diagram is customized—true right down to the caliper bracket and foot controls.




Up entrance is a plan of Yamaha XJR1200 forks, with a customized steering stem, yokes and bar risers. Out help are a model current plan of shocks, curved as so much as a customized swingarm—a bit that Maxime’s boss requested, to command their get hold of praises Hurco’s machines’ capabilities. Made in partnership with the CAD/CAM agency Mastercam, it’s tailor-made specifically for this bike—with exiguous minute print fancy a caliper reinforce mount, and paddock stand helps.

It’s a refined part that wishes to be appreciated up shut; however so are the other customized touches on this Yamaha.




From the engine covers to the paunchy foot pegs, to the complete kickstart lever and pedal, Maxime’s lengthy earlier to metropolis with out going over the tip. Detect even nearer, and also you’ll position further, finer minute print—fancy the emblems etched into the sides of the yokes.

Up prime is an Airtech Streamling tail share, matched to the OEM gasoline tank, a entrance quantity board, and a plan of flat track bars. For the livery, Maxime’s brother, a designer on the Austrian assemble powerhouse Kiska, helped out with over thirty mockups—all of them the utilization of Hurco’s company colors.




The entire factor’s now carried out in unhappy and gray, with two shades of blue for accents (one for paint, and one for anodizing). But another buddy, Jerome, took care of the decals; a nod to the entire confederate companies that labored on the mission.

Not solely does the SR survey hella sharp, but it surely fully’s moreover reportedly a deal with to lumber. Maxime plans to safe sideways with it on a flat track quickly… however besides then, its primary job is to maintain Hurco’s subsequent swap stage to sales space head and shoulders above the comfort.
