Many really feel that BMW boxer customization has turn into a tedious paint-by-numbers affair. It’s a good argument—in spite of everything, most BMW R-series customs observe the identical components so intently, that you just’re in all probability already picturing them in your head.
This thought weighed closely on Takashi Nihira when a buyer particularly requested a BMW R-series construct, but additionally stipulated that it must be attention-grabbing sufficient to command consideration on the prestigious Yokohama Scorching Rod Customized Present. Working with a 1990 BMW R100RS, the person behind Tokyo’s Wedge Bike resolved to create a machine that will rise above the present developments. And with none additional requests from his consumer, he was free to execute his imaginative and prescient nonetheless he noticed match.
Nihira-san’s plan was to construct a svelte café racer with {custom} bodywork that will move cohesively from entrance to again. However quite than create a conventional fly-line alongside the underside of the tank and tail, he aimed to attach the entrance to the again by the use of a tapered ridge operating alongside the facet of every half. Or, as he calls it, a “character line.”
“After I beat out metal and aluminum sheet steel to construct gas tanks and bodywork, I have a tendency to make use of rounded shapes, as a result of they’re straightforward to construct,” he explains. “It’s very troublesome to create an edgy character line on elements produced from crushed metal. However this time, I needed to tackle that problem.”
Listening to Takashi’s phrases and analyzing his work, it’s straightforward to attach the dots. The handmade gas tank and tail part will not be solely impossibly slim, however their shapes and myriad edges echo one another fantastically. The aforementioned ridge line ties the entire thing collectively, accentuated by a tasteful silver stripe.
Takashi has drawn one other parallel line decrease down, by fabricating a brand new aluminum cowl for the highest of the engine. “The one engine that may be utilized as a part of the design is the air-cooled BMW flat twin engine, the place the higher engine cowl might be modified,” he explains. “By including this design ingredient to the motor, I used to be in a position to give it a near-future energy supply really feel—like an electrical motor.”
The general design of the brand new bodywork and engine cowl additionally led Takashi down an sudden path. His regular course of is to sketch a tough draft of the bike he’s constructing, after which to check his idea by shaping the proposed design out of styrofoam blocks which are positioned onto the bike’s bare body. These styrofoam sculptures don’t act as molds although—they’re simply used to prototype no matter concepts Takashi has brewing.
As soon as he begins shaping the ultimate items out of steel although, the proportions inevitably change because the design morphs into an actual motorbike. As that occurred on this construct, Takashi quickly realized that the BMW R100’s offset mono-shock rear suspension was going to conflict along with his clear design.
“Contemplating this bike from a design perspective alone,” he provides, “I might have most well-liked it with out rear suspension, however that wasn’t an choice. So I used to be very anxious about the place to transplant the rear shock. As I thought of it increasingly, I made a decision that I needed to cover it—after which I assumed, why not put it in or underneath the gas tank?”
After contemplating (and eliminating) a number of choices, Takashi settled on mounting the shock ‘inside’ the gas tank, simply to the best of the body’s most important spine. A cutout on the facet of the tank exhibits off the Öhlins shock—however what it doesn’t present, is the linkage mechanism that makes all of it work.
To complicate issues additional, Takashi redesigned the BMW R100’s subframe and swingarm in order that the shock pivot now sits on the left of the bike. Forces are transferred by way of a vertical strut, throughout a horizontal linkage to the alternative facet of the bike, after which to the ultimate linkage and shock that sits up entrance.
It’s a posh answer to an issue that many would take into account nonexistent—however the result’s a motorcycle that seems inflexible from one facet, solely revealing its suspension if you look at it from all angles. And it seems rattling cool, too.
This type of mechanical class is scattered throughout this construct. The subframe help is a single tube setup, with an LED taillight mounted slightly below the tail cowl. Takashi has additionally liberated the chassis of its passenger peg mounts, together with any superfluous tabs.
There’s an identical vibe up entrance, the place a custom-made cross member, mounted between the yokes, performs host to an LED headlight and a set of bespoke handlebars. Classic bicycles supplied unfastened inspiration from the bars, that are deliberately low-slung in order to not mess with the bike’s profile an excessive amount of. The entrance forks are inventory, however they’ve been lowered a contact, and the one piece of seen tech within the cockpit is a small Motogadget speedo.
The bike rolls on 18” cross-spoke tubeless BMW wheels, transplanted from a BMW R100R. Mounting the R rear wheel to the RS swingarm resulted in an offset that Takashi couldn’t abide, so he narrowed the hub and modified the spokes to get it excellent. The entrance brake was upgraded with a Beringer caliper and a Kustom Tech grasp cylinder.
Most simplicity was at all times the purpose of this mission—and Takashi went to nice lengths to realize it. The gas traces and the few wires that there are all run by way of the engine casing to their remaining locations, and the entrance brake grasp cylinder is hidden beneath the gas tank. He even went as far as to switch the BMW’s oil pan, in order that its backside edge would run parallel to the gas tank.
The engine now sports activities a pair of Keihin FCR carbs with velocity stacks, wrinkle black paint on the cylinder head covers, and a custom-made chrome steel exhaust system that sashays its means right into a luscious pair of reverse cone mufflers.
The paint job is worthy of consideration too—particularly since Takashi does all his personal portray. It seems to be a easy metallic blue in these images, however he tells us that the impact solely actually involves life when seen with the bare eye. “I combined mild blue with gold pearl,” he explains, “in order that, relying on the angle of view and the depth of the sunshine, it seems both greenish or golden.”
“When contemplating a brand new design, there’s a strategy of including new particulars. It’s very straightforward—all it’s important to do is fill it with new issues. However then it’s troublesome to create a way of unity within the design.”
“However, it’s very troublesome to create a easy, but new, design. Easy design signifies that, at first look, there isn’t a lot data to soak up. And the novelty you expertise creates a type of discomfort, I assume. Issues we’ve by no means seen earlier than really feel unusual, as a result of we’re unfamiliar with them.”
“I consider that this discomfort and newness should exist inside pure traces and shapes. That’s why the surfaces that make up a motorcycle’s exterior are crucial. And that’s why I used a unique methodology to create the character traces of this bike after which structured the opposite particulars round them.”
“A unique strategy equals a way of discomfort—and difficult this was the theme of this mission.”
