The A–Z of Rider Equipment

AirTex This resistant, net-like Dynafil structure allows air to flow freely, keeping you cool even at higher temperatures. It is extremely light, yet offers all the safety you’d expect from a motorcycling jacket, and is ideal for hot-weather riding.
Azo dyes These may not be used in coloured outer materials since they can break down into carcinogenic amines.
Breathability Technically defined as resistance to evaporating heat transfer (RET). The lower the RET, the more permeable the material is to air.
Carbon fibre Heat-resistant chemical fibre, lighter than glass fibre. Characterized by high strength and rigidity.
c_change ™ Elasticated, abrasion-resistant Dynatec, employed as a three-layer laminate. The intelligent c_change ™ membrane adapts the size of its pores according to the exterior temperature, thus allowing the skin to breathe in hot weather, and locking in heat on colder days.
CE test mark The CE (Communauté Européenne) mark indicates that the product complies with European Union safety directives.
Cordura ® 500 / 700 Nylon yarn consisting of 100% polyamide. The manufacturing process involves respinning and weaving the cut polyamide fibres. Has a melting point of 210°C. Cordura ® 700 is even more tear-resistant.
Design The characteristics of BMW design include the use of classic shapes and colours. The guiding principle is “Form follows function.”
DuPont Coolmax ® DuPont Coolmax ® consists of hollow fibres which transport humidity to the outside very quickly by capillary action, making the material dry 50% faster than cotton.
Dynafil A highly tear-resistant polyamide yarn that is even more robust than Cordura ® 500 / 700 and resistant to high temperatures.
Dynatec Fabric made of Dynafil. Tear-resistant and extremely robust, with a melting point of 290°C.
Expanding pleats The upper material is sewn onto the stretch fabric in a corrugated form. This allows the compound to stretch, making the tear-resistant outer material even safer.
Glass-fibre reinforced plastic (GFRP)/carbon-fibre reinforced plastic (CFRP) The individual fibres (aramid, carbon, glass fibre) can be mixed in varying proportions as required. By changing the orientation and position of the fibres, different characteristics can be achieved – for example low weight, high strength, high rigidity, low heat expansion and good insulating properties.
GORE-TEX® A membrane made of teflon (polytetrafluorethylene). Countless microscopic pores prevent the penetration of large water droplets while allowing the much smaller water vapour molecules to pass through. The branch-like structure of the membrane means that it is also windproof.
GORE-TEX ® Armacor™ An extremely tough, non-tear fabric with Kevlar ® and Cordura ®, that offers the breathability of GORE-TEX ® in a three-layer laminate.
GORE-TEX® Performance Shell A combination of soft fabrics, a GORE-TEX® membrane, and a special lining which provides lasting protection against cold and damp.
GORE-TEX® ProShell The GORE-TEX® ProShell three-layer laminate is 25 per cent more breathable than standard GORE-TEX® three-layer laminates. It is also wind and waterproof, and so provides optimum temperature and moisture regulation – it keeps wearers warm when the weather is cold, and ensures they do not overheat when the temperature rises.
GORE-TEX ®X-TRAFIT ™ GORE-TEX ®X-TRAFIT ™ is a three-layer construction employed in motorcycling gloves. It is windproof, waterproof and breathable, with the layers being glued or laminated together. The lining of the gloves is bonded to the membrane, which in turn is bonded to the leather, ensuring they are easy to put on and take off (even when wet) and offer first-rate grip.
Hydrophobic treatment A treatment which renders leather water-repellent. BMW uses the vat immersion technique, with 3M Scotchguard™ as the active agent. The best results are obtained when only the leather fibres are encapsulated and the pores are left open, thereby maintaining breathability.
Integral helmet A helmet that encloses the head completely.
Jet helmet An open-face helmet with no chinguard or visor.
Kangaroo leather Finer, more closely woven ⇒bres and a tighter structure make this leather even more durable than cowhide.
Keprotec ® A blend of Kevlar ® and PA ⇒bres which enhances Kevlar’s ® already excellent stretchability and abrasion resistance. Used to reinforce those areas most at risk in a fall, such as the elbows, shoulders, knees and thumbs.
Laminate A layered structure of various materials created by thermal adhesion (the adhesive is usually applied in spots), and particularly suited for use with all-weather membranes. Can also take the form of a lining laminate or three-ply laminate, and does not always need to be thermally attached to the outer material.
Motorcycle-specific cut This pattern takes account of the body’s contours in the riding position. The tops of the sleeves are further forwards, the sleeves and legs are angled, and there are numerous other special design details.
Nappa leather The upper surface of the hide. Smooth and slightly shiny, worked to a soft leather with a fine grain.
Nickel-free accessories All BMW Motorrad buttons and zips are nickel-free to protect the skin.
Nomex® A heat-resistant material made of fire-retardant aramid fibres.
Nubuck Leather A highly breathable leather with a slightly roughened surface, resulting in a velvety feel.
Off-road helmet A helmet with a chinguard and sunshield but no visor.
PCP/CP Pentachlorphenol (PCP) is banned under the German prohibited chemicals order of 14 October 1993, though it may be used in concentrations of up to 5 mg/kg in leather processing.
ProFoam A viscoelastic foam which hardens on impact, providing excellent shock absorption at all temperatures.
ProSafe An integral polyurethane foam with an open-cell structure and a closed-cell outer skin that resists weathering and is used in protectors.
Safety, active and passive Active safety measures are designed to prevent accidents, for example by using reflective material for good visibility. Passive safety features aim to minimize the effects of an accident, for instance by employing impact-resistant protectors and outer materials.
Schoeller® PCM Derived from space research, this material features special paraffin capsules that allow it to store heat when warm and release it when the temperature drops. It is thus able to minimize fluctuations in body temperature, keeping the rider comfortable. The material is at its most effective between temperatures of 5°C and 25°C.
Serafil Highly tear-resistant safety yarn used in all BMW Motorrad motorcycle suits.
Silver function A textile treated with silver via an ionizing process that has a longterm antibacterial effect, minimizing odour and moderating body temperature. The material has anti-static properties and wicks moisture away particularly effectively.
Storm cuff A sleeve inlay which forms a waterproof closure around the wrist.
Taslan A group of materials in which the polyamide fibres are altered by steaming. This causes them to swell and soften while retaining their wind and water-resistance and breathability.
TFL® Cool System Cool technology is used in dark leather and textile garments. Thanks to a special manufacturing process, sunlight is reflected from the dark surface of the leather or fabric in the same way as from a light surface, making the outer material much less likely to overheat.
Venturi This breathable wind and waterproof membrane is used as a laminate in BMW Motorrad Rider Equipment. Its main advantage is its low weight, and it can also withstand water pressure at depths of up to 10 metres.
x-static® A textile containing silver which prevents bacteria, odours and static, and regulates the temperature.
Z-liner Here, the membrane is like a lining ”suspended” between the outer material and the lining itself.
