Description:

Jeans on the bike – that is casual, it’s loose. But what happens when an involuntary asphalt contact? If you then away with a few bruises? 13 pants and jackets made for five MOTORBIKES a departure.

Svenni poor. At a speed of 80 it knocks him off the bike, the knee strike on hard, Rummer, he tries to support himself in vain, then slams his helmet visor on the asphalt drags on the abdomen a few meters, is thrown to the side, flying fragments, and only after a glissade of more than 25 meters, it remains in a cloud of dust and lint lie motionless. The volunteers come running up and turn the casualty onto his back. Svenni has a tough job that nobody else wants to do. He is of indeterminate age, approximately 1.75 meters tall, 90 pounds in weight, more of a silent type. Svenni’s crash test dummy. A loan from the Dekra and very valuable to the great Jean-MOTORCYCLE test because Svenni can fall until you drop. Normal, vivid test drivers try to avoid this course. Driving under the sun and the south of France to check the fit and comfort are, as compared to Svennis use a piece of cake. Just like the daily standings of the textiles.

In the end, however, primarily interested in this: how much security the Klamotte offers in the fall? And without a crash test Svenni who was catapulted from a motorcycle developed by ADAC-ejection device (see photo show) in the direction of asphalt, this question could be answered no. But back to the beginning. Why is this test? Not only within the editorial is the subject of “jeans on the bike,” controversial. Only one can be happy once its complete equipment are left and sometimes just slips into “my old jeans” to cruise into the city or to the quarry pond. Keyword Cruiser: Certain types of refuse on principle technical motorcycle apparel as unfashionable and make you feel blue when it comes to safety equipment. However, the designers now offer a variety of special motorcycle jeans with protectors (or retrofit facilities) and reinforcements with Kevlar (aramid) as a better choice for the traditional fashion jeans. The most expensive pants in the test, Strong Esquad costs, including nearly 400 € protectors.

An impressive sum, especially as the cheapest, Icon Victory, only a fraction of that price expensive, would also play in the league of motorcycle clothing, even if they differ at first glance hardly a normal pair of jeans.

And even when the item featured jackets were clearly big differences – not only on price. The buyer has therefore to distinguish and decide. Therefore, this test, in addition to the security aspect but will also clarify other questions: How can the blue fabrics to go on tour, how easy it is to use the clothes? Disrupt the shopping center or stroll the protectors, or is it due in the summer of Materialdoppelungen even sweats? The coolness factor is way deliberately hidden from the review because whether an intersection like the “baggy” or “slim fit” to wash “vintage” or “raw” should remain a matter of taste.

The processing is in turn as a hard test and criterion affects the overall score. Once more to the discharge test (see individual results in the products): He provided important clues to the protection of a fall, but can not provide eventual truth. The bombing occurred while always from 80 km / h at the same place, the dummy fell and slid but each time something different. In the evaluation of the wear pattern and the degree of destruction, this was taken into account accordingly. Just as the seat of the Protectors, this was previously placed in the driving test on the touchstone. Florian Schueler, accident investigators from the University of Heidelberg emphasizes just this aspect: “Are there protectors and keep them in the fall and at the place where they belong is not the case, lacks the most important protective function.”

The researcher explains why. So-called abrasion injuries, in German: abrasions were indeed very unpleasant but rarely dangerous as the many injuries that would be incurred by collisions with edges, poles or rock. And it is only approved protectors – it noted, well-fitting – in this nightmare scenario would offer the best protection.

Are not entirely without abrasions yet? Depending on the nature of the asphalt (rough, smooth, loose chippings, etc.) and relevant parts of the body can slip in a batch of several meters, first the skin, muscles and tissues, and even then arteries and veins are pulled in the affected.

In extreme cases, threatened with a severe increase in blood loss and it can even grind bones. So about the gas gangrene a severe wound infection. Certain bacteria of the genus Clostridium form poisons (toxins) that cause the tissue death associated with gas formation. The flood of toxins in the bloodstream – within a few hours from a life threatening situation can arise. Accident investigators thus warns students: “Driving with normal jeans, his naked as the fabric is still straight away..” The after-discharge test MOTORCYCLE badly mangled fashion jeans for 19.90 € students are right.

This, however, to conclude, jeans are always bad, and normal motorcycle clothing protects one from a bad beating in the truest sense, would be wrong. The test showed, namely, that a single-ply motorcycle textile pants import from really hard-wearing Cordura (nylon), a catastrophic result, and also a slightly graying leather suit looked after the drop is not necessarily better and trousers as the most tested denim jackets.

Some of the jeans made after the crash test, however, a lively impression, and even went as trendy Buxe through hole with a discreet design.

Hans-Peter Fleischmann of the Hohenstein Institutes in Bonnigheim (Textile Research Facility) hardly surprising that “jeans were originally worn as work clothes, must be able to put away from home a lot.” Jeans, more precisely, denim fabrics (from “serge de Nimes”, tissue from the French city of Nimes) consist of a so-called body tissue that is particularly strong. Their good durability, they obtained by using heavier yarns. “This is really a lot of material,” says the clothing expert, but points out that the quality (measured in ounces) not only depends on the severity of the tissue, but significantly on the quality of cotton. Fleischmann: “The longer the fibers can be, the better the yarn produced. The problem with the naked eye one can see the little.”

The test also showed that the abrasion Materialdoppelungen play a crucial role. Summary: Solid, thick denim fabrics to survive, even with good processing crude falls comparatively well. During a phase slip can be made of around 100 km / h at the clothes by Reibhitze selectively develop a temperature over 200 degrees Celsius, the blend of polyamide and polyester synthetic fibers in the skin to burning debris. Cotton fibers, however, as it verflocken abfackelndes paper – dissolve into thin air – and the underlying tissue in the ideal case of aramid fibers carbonize until around 400 degrees.

In an emergency, then the injuries would probably turn out less than many comparably priced motorbike textile suits without additional Kevlar protection. Jean-motorcycle clothing but can not replace a tight-fitting, high-quality leathers. And slim-fitting suits with high-end textile many options, Materialdoppelungen and vulnerable areas highly abrasion-resistant fabrics such as Cordura and Schoeller, 1000 dynatec or leather trimming of the “blue men” probably trumps either. Motorcycle jeans and jackets are and will remain a compromise. Especially in summer, but a pretty good, not because you sweaty and overheated way is – the active safety of the driver’s certainly doing well. Svenni was full-bodied despite its commitment to the way relationships healthy and happy again packed into the crate. After more than 20 ground contacts on hard asphalt airfield remained only a few scratches. Well needless to say, that one, even with the best motorcycle wearing jeans, was better left to professionals such Schlitterpartien with replaceable rubber skin.
