BMW R 1200 GS Jararaca

Bavarian cosiness is over for the boxers. This is what this species of R 1200 GS proves at the latest: not a friendly platypus, but an aggressive venomous snake. Careful, snappy.

The visitors to the Wilhelma, Stuttgart’s magnificent botanical-zoological garden, have not seen that yet: A two-meter-long strangler of the species Boa constrictor lolls on a motorcycle, enjoying the heat radiation of the cooling boxer. A kind of affinity, because the machine is named after a South American lance viper, the poisonous Jararaca. “Everyone in Brazil knows and fear this animal,” explains tuner Erich Wunderlich. He should know because he was born in Brazil and spent the first five years of his life in the Amazon.

In 1985 Wunderlich started with tuning parts for Yamaha SR and XT, today his think tank in Sinzig only tunes BMWs. The current catalog serves as a 480-page bible for BMW drivers. It also neatly lists the conversion kit for the Jararaca so that they can multiply in our latitudes. All parts fit together modularly.

Despite a good GS basis, the people at the motorcycle meeting point remain in a state of fright in front of the strange creature like the rabbit in front of the snake. The Jararaca stands there as if freshly hatched from the egg; rests on the side stand with an enlarged footprint, the main stand and the pillion seat are dismantled. Her beakless, grim-edged front mask could come from a science fiction film. This contrasts with rounded tank panels, in their
Hella auxiliary headlights have bulges. The xenon lamp on the left, coupled with the high beam, shines almost too brightly during nighttime forays. If you have to stop the lights, you can only see in the dark. In contrast, the fog light shines modestly.

A standard GS has no side panels, the Jararaca does. Painted blue and silver like the front, they continue the line. The same applies to the rounded tail light cover, also made of solid-colored plastic (ABS). All of these cladding parts together cost less than 900 euros, including adjustable mini windshields “Flowjet”. It protects surprisingly well, offers honest wind pressure without turbulence and a fairly quiet noise level. That‘s a good thing, because the Jararaca area is itself a German motorway.

This is ensured by flawless straight-line stability and more liveliness and power at high speeds. At the heart of the GS rotate »boxer boost« camshafts with sharper control times: more elevation and greater valve overlap. The four-valve engine hangs wonderfully directly on the gas. It is only after 6700 tours that it is definitely ahead. Below this mark, for example in the urban jungle, a series GS usually even has a little more torque. The running smoothness of this example is poor in the partial load range. Especially when idling, the cold-blooded, i.e. air-cooled flat twin shakes unwillingly. On brisk hunting stages, it burns more than nine liters of high-octane concentrated feed per hundred kilometers.

The titanium-coated double-pipe exhaust »TwinBoost« from HPE sounds animatingly pithy. Only its driving noise is too high? see exhaust test for the R. 1200 GS in MOTORRAD 12/2005. At least he breathes out via G-Kat. This Jararaca nimbly meanders through the asphalt thicket as its role model through the bushes. Super direct takes on the 1200 steering impulses. The wide Magura handlebars ensure great handling ?? it is flatter than the series, but rests on higher trestles ?? and road tires on black painted GS cast rims, 17 inches at the rear and 19 at the front.

Michelin Pilot Road deservedly won the tire test for travel enduro bikes in MOTORRAD 10/2005. Bibendum, the Michelin mascot, greets you happily from the sidewalls. Even the driver has
every reason to be happy, the martial BMW hammers around the corner with such precision. As if a black mamba bites. The higher positive profile share of the Pilot Road stands out positively. And they stick very well even in the rain. In the border area, they warn in good time like a rattling rattlesnake before the monster cow begins to push over both wheels.

When things get too thick, Wave brake discs from Braking, including standard calipers, will surely catch the Jararaca again. Despite the brake booster, it can even be dosed to some extent. A shortened rear Wilbers shock absorber does not allow the rear to stand quite as high, minimizes its life of its own. However, at the expense of convenience, it’s clearly too tightly tuned. This applies even more to the Wilbers colleague at the Telelever. Every small expansion joint in the asphalt is passed unfiltered to the wrists and buttocks. The Kahedo single seat, which is available in two heights, can pamper the very best.

From conjuring snakes to eye-catching: Noble carbon laminate is used for the fenders, valve and generator covers. And many nice details make dealing with the reptile easier in everyday life: the boot is easier to thread under the foldable, three-centimeter-length adjustable lever, resulting in more switching precision. A pure lead battery provides safe starting current at all times.

A “Blue” permanent air filter made of cotton fabric only requires every 50,000
Kilometers after cleaning. Transparent adhesive films, which otherwise protect aircraft propellers, preserve the painted skin
the jararaca in the most stressed areas from abrasion damage. Aspherical mirrors minimize the blind spot, an aluminum handle helps when jacking up. The boa constrictor likes the tester
so many conversions are astonishing. Well, the metamorphosis was a complete success.
