An emotional machine that blends the aesthetics of a endurance racer with an air-cooled boxer! BMW R100RS

Inspired by the endurance racers of the 1980s, this machine isn't a mere replica of the bikes from that era, but rather a reinterpretation that captures their spirit and philosophy, rebuilt into a form that the owner desires to ride today.
We introduce a BMW R100RS, customized with a modern touch using parts from other models, while fully leveraging the charm of its air-cooled boxer engine.

1993 BMW R100RS

What is the BMW R100RS?

The R100RS, introduced in 1976, was the world's first mass-produced sport tourer featuring a full fairing.
Equipped with an air-cooled horizontally opposed twin-cylinder engine, it is known for its ability to achieve a high level of both high-speed cruising performance and long-distance comfort.

The R100RS was almost entirely stock when purchased.

Three years after purchase, this photo shows the bike without its fairing.

Drawing and Crafting

Cars, motorcycles, and even girls.
Illustrator "surakusu" draws them to blend seamlessly into the same atmosphere.

Her pop and charming illustrations have a relaxed feel, leaving the viewer with a comfortable sense of space and atmosphere.
Her worldview extends beyond mere visual expression, touching upon the concept of "how things and people should be."

This BMW R100RS is also a creation that stems from this philosophy.
It is shaped not by specs or accuracy, but by a sensibility of "how it wants to be."

Wearing the "Context" of Endurance Racers

The starting point for this project was a friend who owned the same model.
This sparked the owner's interest, and they were drawn to the simple structure of the "air-cooled twin/carburetor" setup.

Although they missed an opportunity to purchase one once before, it was a bike they were determined to own, thinking, "Next time, for sure."

The customization theme is endurance racing machines from the mid-1980s.
It's based on the atmosphere of the era, reminiscent of races like the Suzuka 8 Hours and the Barcelona 24 Hours.

However, the goal was not to create a copy.
It was to rebuild it into a form that the owner "wants to ride today."

With this philosophy in mind, the overall form and composition were assembled.
The coloring, in particular, was a point of focus, with 20 to 30 patterns considered.

The Essence of Riding, Beyond the Appearance

The uniquely smooth cruising feel of the air-cooled boxer twin.
And the stable cornering performance brought about by its low center of gravity.

This R100RS is not a motorcycle that is complete with just its style.
In fact, its true value shines through when it's ridden.

A beautifully balanced side view in terms of both coloring and form.

The stability and feel provided by the low center of gravity, unique to the boxer twin, enhance cornering confidence and riding enjoyment.

Details Composed of Parts Swaps and One-Offs

The R100RS is not exactly a mainstream choice as a tuning base.
Therefore, the customization primarily involves parts swaps and one-off fabrication, rather than relying on off-the-shelf parts.

・Alpha Racing NS250R cowl (modified)
・Ducati MHR single seat (manufacturer unknown)
・Daytona 80φ digital meter
・41φ fork from a Japanese model + Bitubo fully adjustable cartridge
・TL1000S 4-pot caliper
・Frando radial pump master
・Bitubo rear shock
・MAC megaphone silencer
・Ritmo Sereno rearsets

The ingenuity of using parts from different models and the functional upgrades are seamlessly integrated.

The cowl, the most distinctive feature of this vehicle, is a modified Alpha Racing NS250R part.

The Ducati MHR single seat further enhances its racy appearance.

The suspension system is a serious setup, featuring a fork from another model and a TL1000S 4-pot caliper.

A neatly organized cockpit area.

The meter chosen is a Daytona 80φ digital type.

The rear section features meticulous attention to detail, including Bitubo rear shocks, MAC megaphone silencer, and Ritmo Sereno rearsets.

Customization as Expression

Drawing and making.
Though they seem like different activities, the underlying principle is the same.

How do you want it to look?
How do you want it to be?

The answer to these questions has taken the form of this BMW R100RS.

Clad in the context of endurance racers, it becomes a machine that belongs nowhere.
It is not merely a custom bike, but an "expression" that projects the owner's aesthetic sensibilities.

This can be said to be a unique BMW R100RS that embodies the aesthetic sense and sensibility of an illustrator.
