It should really go without saying that Yamaha’s XJR1300 is a perfect candidate for customization. As time went by, we’ve looked at countless XJR-based entities bred by some of the world’s most prominent workshops, such as Deus Ex Machina and Denmark’s revered Wrenchmonkees. Recently, the autoevolution pages were adorned with a ‘99 MY specimen that's been treated to an eerie makeover at Poland’s topmost aftermarket clinic – Unikat Motorworks.

Today, we’ll be examining yet another bespoke head-turner that revolves around the mighty XJR, namely Bad Winners’ “Muscle Retro.” More than a decade has passed since Walid Ben Lamine founded BW in the 19th arrondissement of Paris, so it’s fairly reasonable to say these folks know exactly what they’re doing!

In its previous incarnation, the bike you’re seeing here was a factory-spec 2005 model from Yamaha’s discontinued line-up, featuring a 1,251cc inline-four mill that’s good for up to 98 hp and 80 pound-feet (108 Nm) of twist. Although most of us would be perfectly satisfied with those numbers, the French specialists were determined to take things to the next level.

As such, they installed a new ECU, a Stage 1 jet kit from Dynojet and a premium set of Wiseco pistons, while the cylinders were bored to raise capacity. Following the overhaul, the engine’s displacement has been boosted to 1,390cc, resulting in a peak horsepower figure of no less than 128 ponies at the rear wheel. To top things off in the powertrain department, BW replaced the original exhaust with a stainless-steel four-into-one alternative, which terminates in a tiny muffler from Spark.

Suspension duties are taken good care of by a Suzuki GSX-R1000's higher-spec forks up front and dual Ohlins piggyback shocks down south. The Gixxer also donated its brakes and front wheel, whose rim sports Continental’s top-grade ContiAttack SM EVO rubber. A Koso LED headlight can be seen taking pride of place in between the repurposed forks, while the cockpit comes equipped with a Motogadget speedometer, Motone switches, and a Renthal handlebar.

Lastly, we spot a loop-style subframe and one gorgeous custom saddle down south. If you’re digging this beast as much as we are, you’ll be intrigued to learn that Bad Winners will be more than happy to build it again for €13,500 ($15,675 as per current exchange rates).
