AI-assisted summary
Description from the seller
The item for sale is the legendary BMW System motorcycle helmet (most likely Systemhelm 4) in a striking, vivid red color. It is an ideal proposition for the owner of a classic BMW motorcycle, a collector, or someone who values reliable engineering solutions from the Bavarian brand's best years of production. The helmet visually presents itself superbly – the outer shell is kept in very good condition, the paint has a deep shine and only minimal signs resulting from normal use, as shown in the attached photos. The visor is clear, and the chin-bar lifting mechanism works precisely and smoothly. However, it should be noted that due to the helmet’s age, its interior needs attention. The inner foam lining has undergone natural oxidation and crumbled, which is a standard issue for helmets from this period. The inner EPS shell is undamaged, but for full comfort and hygiene, the new owner should replenish the padding or subject the interior to professional renovation. It is an excellent base for refreshing, which after minor internal service work will regain its former glory and will serve for many more years, providing a stylish complement to motorcycle equipment. I cannot determine the size of this helmet.
The BMW System 4 helmet was designed with a focus on safety and aerodynamics, which at the time of its release placed it at the forefront of jaw-caps helmets. Here are the main materials used in its construction:
Outer shell: Made from high-quality thermoplastic reinforced with fiberglass (GFK). By using composites, the helmet is stiffer and more impact-resistant than cheap models made of pure plastic (ABS), while still maintaining a relatively light weight.
Liner (inner shell): Made from expanded polystyrene (EPS) of varied density. This layer is responsible for absorbing impact energy.
Visor: Made from high-clarity polycarbonate (scratch-resistant). Interestingly, BMW used anti-fog coatings in this model.
Interior padding: A combination of soft synthetic fabrics (often Velour or breathable materials) with polyurethane foam. It is this foam, due to the passage of time, that undergoes natural oxidation and crumbling, as you mentioned in the auction description.
Chin-bar mechanism: The locking elements and hinges are made from a combination of stainless steel and durable plastics (polymers), which ensured the mechanism’s durability despite repeated opening. Height around 22 cm, width around 22 cm
I do not ship to the USA.
