How should a motorcycle suit fit correctly?
Small details make a big difference...
The cut of all 4SR motorcycle leather suits is based on years of experience from racetracks, many crashes, and feedback we receive from professional racers. These valuable insights are applied in the final products for our customers. And since we want to manufacture only top-performing leather suits, all our motorcycle leather suits are identical. That's why we don't have different equipment and price lines for production suits. One that works is better. Simply the same quality for everyone.

WRIST: FINE, THIN, AND SHORT This is exactly how the wrist of a sport leather suit should look. That's why the sleeve on 4SR leather suits is always shorter and finished with a thin aramid stretch cuff. Such finishing allows free movement of the wrist, and as you surely know, it's with your wrist that you control the motorcycle. |

FLEX PANEL ABOVE THE KNEE PROTECTOR Above the knee protector, one of the flexible panels (leather accordion) is sewn in. When standing, this panel is gathered. When sitting on the motorcycle, the panel stretches so that the knee protector can always be in the correct position and the bending of the knee is as comfortable as possible. Unrestricted movement is, after all, the foundation of safe and fast riding. |
 |
ERGONOMICALLY SHAPED KNEE The perfect shape of the leather suit's knee, besides ensuring comfortable riding, is designed to secure the protector during movement and in the event of a fall. For this reason, the leg is composed of several segments. Leather section, shaped to the knee and flexible, with an aramid stretch panel ensuring flexibility in the back of the leg. |
 |
BACK FLEX PANEL The largest flex panel on the 4SR suit is located in the lumbar area. It allows for easy tucking in on the motorcycle, as it can stretch to almost double its length. Also, when shifting weight and quickly leaning the bike, the lumbar flex panel and its function are crucial for the feeling of freedom and full range of motion. |
 |
LEG LENGTH A motorcycle suit goes into the boots, so the legs must be as short as possible and the bottom hem should be as narrow as possible to avoid pressure inside the motorcycle boots. You can easily check the correct leg length in the riding position on the motorcycle. |
 |
STRETCH IN THE GROIN AREA Proper motorcycle control requires weight transfer. A basic movement example is hanging off in a corner, which is precisely why an elastic material is used in the crotch area. However, this part must not be assembled from multiple pieces, because connecting seams would restrict the rider's movement. To ensure movement is not limited by seams in any direction, we use one large piece of aramid stretch. Thanks to the seamless cut, movement and weight transfer on the motorcycle is a true joy. |
 |
SHAPED TORSO, SLEEVES, LEGS, AND SHOULDERS The suit's cut is ergonomically adapted for the position on the motorcycle, which is why the legs, torso, sleeves, and even shoulders are pre-bent. That's why you'll always feel your best behind the handlebars in your suit. |
