Nitrocycles’ aesthetic tweaks are obvious, but just wait until you read about the performance upgrades.
In the past, we took a look at Nitrocycles’ inventory and admired a few of their juiciest exploits, including a handsome Suzuki GS850 and one sexy piece of custom machinery based on Honda’s CB750 F2, to name a couple. It’s not hard to see why this Madrid-based enterprise is one of Spain’s go-to places when it comes to personalizing your two-wheeled companion.
The project we’ll examine today revolves around a 1986 BMW K100RS. From the factory, this bad boy is brought to life by a liquid-cooled DOHC inline-four powerplant that boasts a gargantuan displacement of 987cc. At approximately 8,000 revs, the four-stroke fiend will be more than happy to produce as much as 90 hp, along with 63 pound-feet (86 Nm) of twist at 6,000 rpm.
A five-speed transmission is tasked with handing over the engine’s oomph to a shaft final drive, enabling the K100RS to accelerate 0-62 mph (0-100 kph) in just 4.3 seconds. Furthermore, the top speed is generously rated at no less than 136 mph (220 kph). Now, let’s see what the Nitrocycles team brought to the table, shall we?
For starters, the bike’s chunky inline-four mill was thoroughly refurbished, receiving a selection of fresh internals and polished engine covers. Next, the stock subframe was tweaked to accommodate a fiberglass tail section fabricated in-house, as well as a single-seater leather saddle. On the other end, you will find a retro-style headlight and a one-off front fairing resembling that of a classic Ducati SuperSport.
Speaking of lights, the new tail unit comes equipped with an integrated aftermarket item that’ll handle rear lighting duties without adding any visual bulk. The cockpit hosts a fresh pair of clip-on handlebars and a digital speedometer sitting behind the windshield. For a considerable improvement in the handling department, the beast was blessed with rebuilt forks, a Hagon monoshock, and high-performance tires on both ends.
Last but not least, a set of high-flow pod filters allows the engine to breathe a little more freely, complemented by an Akrapovic muffler on the opposite end of the combustion cycle. To top it all off, the entire structure was enveloped in a two-tone color scheme, consisting of gunmetal grey and satin black.
