This graceful machine will have you spellbound!
When it comes to producing state-of-the-art aftermarket components or crafting ravishing custom two-wheelers, Japanese manufacturers are the real MVPs, and no wonder. I mean, it only makes sense that a healthy deal of ambitious workshops will be established in a country that hosts the likes of Kawasaki, Honda and the revered Yamaha, right?

One such enterprise goes by the name of An-Bu Custom Motors, a reputed moto surgeon crew that goes about its daily business in the stunning city of Nagoya, Japan. Besides creating some seriously rad one-off rides, these specialists pride themselves with an extensive inventory of custom goodness that’ll have your bike perform like an absolute showstopper.

As to An-Bu's gorgeous works of two-wheeled art, they include a glorious Harley Davidson XL1200S Sportster, a funky Ducati 750SS and one splendid XS650 from Yamaha’s lineup, to name a few. Quite frankly, it goes without saying that each and every single one of these fascinating superstars does a wonderful job at dropping jaws and raising pulses.

If this stirs your curiosity, then you may want to consider paying these folks a visit on their social media profiles, where you’ll discover some truly drool-worthy feats – after we take a minute to examine their remarkable accomplishments on BMW Motorrad’s feral K100RS, that is.

Let’s set things straight, the Bavarian tourer is one hell of a donor to work with. It is brought to life by a wicked four-stroke DOHC inline-four powerplant that exhales through a stainless-steel four-into-one exhaust. This malevolent liquid-cooled entity houses a total of eight valves and a solid compression ratio of 10.2:1. Additionally, it packs an astronomical displacement of no less than 987cc.

At 8,000 rpm, K100RS’ vicious mill is capable of producing up to 90 hp, accompanied by 63 pound-feet (86 Nm) of malicious twisting force at around 6,000 rpm. A five-speed gearbox enables the engine’s monstrous power to reach the rear wheel via a shaft final drive. Ultimately, this state of affairs leads to a 0-62 mph (0-100 kph) acceleration time of just 4.3 seconds, while top speed is rated at 136 mph (220 kph).

Up front, suspension duties are handled by a set of telescopic forks, coupled with a Paralever unit on the opposite end. Stopping power is provided by dual 285 mm (11.22 inches) discs and twin-piston calipers at the front, joined by a single brake rotor and a one-piston caliper at the rear.

Now, when this bad boy landed on An-Bu's doorstep, things kicked off with the removal of its factory bodywork items, except for the aluminum fuel tank. In their stead, the team installed several modules that were fabricated in-house, such as a slim tail section with an incorporated LED lighting package, as well as a fiber-reinforced polymer front fairing that hugs an eccentric headlight.

Furthermore, the Japanese gurus selected a pair of clip-on handlebars from their very own range and equipped them with Rizoma Spy-R bar-end mirrors and Aries grips. You will also notice rear-mounted foot pegs, top-grade Avon Spirit ST tires and a Chronoclassic gauge from Motogadget’s catalogue.

In terms of performance upgrades, K100RS’ front suspension received a comprehensive makeover, while its rear counterpart was blessed with a juicy YSS monoshock. Last but not least, the inline-four colossus breathes a little more freely, thanks to an ominous exhaust and a carbon fiber muffler.

Right, since we’ve wrapped this up, the next places you ought to be heading are An-Bu's Instagram and Facebook profiles. Trust me; their portfolio guarantees to soothe your soul!
