This Bespoke Buell 1125R Wears A Classic Gixxer’s Unmistakable Front Fairing

Although this workshop may not necessarily be among the nation’s most popular firms when it comes to crafting one-off motorcycles, its portfolio is certainly worth checking out. Needless to say, the custom undertaking we’ll be examining today shows you exactly why that is.

At its core, this mechanical warrior is a beefy 1125R from Buell’s lineup, which happens to be one of the ill-fated manufacturer’s juiciest machines, if you ask me. Before we go into any details on the build itself, let’s take a second to remind ourselves about some of the original bike’s main specs and features, shall we?

Within its aluminum skeleton, this nasty animal houses a Helicon 72° V-Twin powerplant that boasts a four valves per cylinder head and an astronomical displacement of no less than 1,125cc. Additionally, the liquid-cooled colossus prides itself with a healthy compression ratio of 12.3:1.

At approximately 9,800 rpm, the four-stroke DOHC mill is perfectly capable of summoning up to 146 feral horses, while as much as 82 pound-feet (111 Nm) of ruthless twisting force comes in at 8,000 revs. A six-speed transmission feeds this monstrous oomph to the rear six-spoke cast alloy wheel by means of a belt final drive.

Ultimately, this state of affairs enables the 1125R to run the quarter-mile in just eleven face-melting seconds, while top speed is generously rated at 151 mph (243 kph). Long story short, it’s quite safe to say that Buell’s leviathan is a force to be reckoned with among large-displacement entities. Personally, I find its design language and proportions to be slightly odd, but we can probably all agree that LYS did a wonderful job at fixing that aspect.

The crew kicked things off in the bodywork department, where they proceeded to install an assortment of fresh items to give this creature a personality of its own. Up front, you will find a 1987 Suzuki GSX-R750's iconic fairing hosting a smoked windshield, dual aftermarket headlights, and a pair of Motogadget M-blaze turn signals.

Furthermore, the Frenchmen went about sculpting air scoops on both sides to ensure that 1125R’s twin radiators can breathe with ease. On the opposite end of the structure, we spot a steel tail section borrowing cosmetic elements from sport bikes of the previous century.

Thanks to the manufacturer’s fuel-in-frame design, LYS was able to fabricate a custom box that wears a K&N air filter where you’d normally find the motorcycle’s filler cap. The cockpit is adorned with a billet aluminum top clamp developed by USVracing, as well as a tasty set of clip-on handlebars.

Next, the bodywork was blessed with a matte grey finish from Mercedes-AMG's color palette, while the frame received a stealthy coat of satin black for contrast. The French moto masters tasked AdC Sellerie with upholstering a single-seater saddle to round out the visual pizzazz. Last but not least, the finishing touch comes in the form of a unique exhaust system produced by the experts over at IRNOX Motors.

And there we have it, ladies and gents. What’s your take on LYS Motorcycles’ muscular behemoth?
