Tool Time: A Yamaha SR500 built by a machine tool company

There’s nothing unfamiliar about constructing a custom motorcycle with the major motive of taking it to a diploma to. However what if the level to in quiz has completely nothing to lift out with custom bikes? That’s a frosty twist.

This sharply styled Yamaha SR500 flat tracker is the pet project of 27-one year-ragged Maxime Fontvielle. He’s an software program engineer at the French operation of the US machine software program firm, Hurco—a career he bought into thanks to a love of two wheelers.

“When I change into once a teen,” he tells us, “I change into once hooked in to mopeds. Whereas taking a survey at the boards, I seen individuals making parts for competitive 90s mopeds and I believed, that’s what I desire to lift out! I went the total skill in with apprenticeships at completely different corporations, then I arrived at Hurco.”

Maxime stumbled upon a wrecked Yamaha SR500 for true €100, and had a intellectual belief: rebuild it as a showpiece for his firm, to expend to machine industry swap shows.

“Every person year at the swap shows,” he says, “the total manufacturers level to their recent machines in motion with traditional parts from the aviation industry, and heaps others. I believed it lacked a exiguous ardour and soul.”

“I wished to assemble an very honest correct looking out bike with machined parts on it. I proposed to my boss that I prepare this bike as an right flat song beast. American discipline, American firm… right here is a match!”

Maxime’s boss wisely gave the OK—but there change into once a true three-month closing date earlier than the next level to. So Maxime determined to divide and overcome. He entrusted the engine rebuild to the Parisian workshop Machines et Moteurs, with a extraordinarily explicit guidelines, whereas he centered on the chassis.

The motor came aid with a 540 cc equipment and a heck of different internal fettling. Highlights contain an upgraded camshaft, improved oil journey alongside with the dawdle, a Mikuni TMR36 carb and a K&N filter. There’s furthermore a brand recent header and reverse cone megaphone muffler, each from SC Challenge in Italy.

Maxime’s first job on the chassis change into once to install a 19” rear wheel to compare the entrance. He ended up sourcing a second SR unit, and machining it to expend a sprocket and a 300 mm brake disc. Then he machined custom wheel axles, tailored the entrance to elope with bigger bearings, and lightened each wheels by ‘splitting’ the spokes.

There’s no brake on the entrance, but there’s a Brembo caliper and grasp cylinder out aid, linked by a braided chrome steel line. Since Maxime change into once upgrading the bike from a rear drum brake, your complete diagram is custom—true down to the caliper bracket and foot controls.

Up entrance is a plan of Yamaha XJR1200 forks, with a custom steering stem, yokes and bar risers. Out aid are a brand recent plan of shocks, curved as a lot as a custom swingarm—a section that Maxime’s boss requested, to command their obtain praises Hurco’s machines’ capabilities. Made in partnership with the CAD/CAM firm Mastercam, it’s tailored namely for this bike—with exiguous minute print fancy a caliper make stronger mount, and paddock stand helps.

It’s a refined section that wants to be appreciated up shut; but so are the opposite custom touches on this Yamaha.

From the engine covers to the paunchy foot pegs, to the full kickstart lever and pedal, Maxime’s long previous to metropolis with out going over the tip. Detect even nearer, and you’ll role extra, finer minute print—fancy the emblems etched into the perimeters of the yokes.

Up top is an Airtech Streamling tail share, matched to the OEM gas tank, a entrance amount board, and a plan of flat song bars. For the livery, Maxime’s brother, a designer at the Austrian assemble powerhouse Kiska, helped out with over thirty mockups—all of them the utilization of Hurco’s corporate colours.

The complete thing’s now performed in sad and grey, with two shades of blue for accents (one for paint, and one for anodizing). Yet any other buddy, Jerome, took care of the decals; a nod to the total accomplice corporations that worked on the project.

No longer only does the SR survey hella sharp, but it completely’s furthermore reportedly a treat to lumber. Maxime plans to secure sideways with it on a flat song soon… but except then, its main job is to keep Hurco’s subsequent swap level to booth head and shoulders above the relaxation.
