What Size Top Case is Needed for a Full-Face Helmet?

Shad 29, here is the relevant information: 1. The specific differences between full-face and half-face helmets: The main difference between full-face and half-face helmets lies in their safety ratings. Compared to half-face helmets, full-face helmets offer much higher safety ratings, providing excellent protection for the human head by fully enclosing it. Full-face helmets offer perfect head protection but lack ventilation, making them feel stuffy when worn. They are more suitable and warmer in winter. Half-face helmets, on the other hand, offer better visibility and ventilation but are not ideal for winter use. 2. Brands: Well-regarded helmet brands include SOL, Aidel, RuiShi, HJC, and SHOEI.
When it comes to the size of the top case needed for a full-face helmet, I think starting from 35 liters is a safer bet. My full-face helmet measures between 38 to 40 cm in length, with both width and height exceeding 25 cm. It was a tight fit in a 32-liter top case, but the 42-liter one I'm using now fits just right. Besides size, the internal shape also matters—square top cases are easier for helmet storage compared to round ones. If the top case is too small to fit the helmet while riding, carrying it around is quite inconvenient. I recommend measuring your helmet's maximum dimensions before purchasing and choosing a top case with a slightly larger internal diameter, leaving some room for gloves or small items. A 35 to 45-liter capacity is a common choice—too small won't fit a full-face helmet, while too large adds weight and affects balance, reducing riding stability. I usually recommend 40 liters as a starting point, having tested multiple brands with reliable results. When storing the helmet, remember to place a soft cloth inside to prevent scratches on the paint, making maintenance easier. Opt for durable plastic or metal top cases for better theft resistance. In short, you'll only know which one suits you best after trying it out yourself.
