Sporty Kevlar jeans that are properly fitted to maximize comfort and keep that sharp sports style and feel! These are the new Club Sport jeans from the 4SR.

When developing the 4SR Club Sport jeans, we have used our experience from World Superbikes technology, to ensure these sporty jeans, work in the same way as our racing Leathers, using flexible panels above the knees.

Flexible and elastic Kevlar® by DuPont, has been used to produce these jeans, to ensure maximized comfort and mobility while riding your motorcycle.

The 4SR Club Sport Jeans also have ventilation that is strategically placed on the upper thighs, right next to the side pockets. The location of the ventilation on the upper thigh reduces the risk of injury from the zip for the wearer. For added safety, the vent is also covered with Kevlar, for extra protection.

Like any other garment we produce at 4SR, the Club Sport Jeans are equipped with quality knee protectors, which are of course to the highest level 2 T + certification and with the ergonomic 3D shape of the protector not only protects the knee but also the shin.

Thanks to the development of our professional riders along with our experience in the world of motorcycle and world championship motorcycle racing, we know that the right shape of the protector is one of the most important aspects.

4SR Jeans are still the only Kevlar jeans on the market that have the fixation of the guards in the right place and meet the highest standard requirements. 4SR have the patented AFS - Armor Fixation System.

How does the 4SR AFS work? The trousers have a loose elastic stocking that holds the knee and shin protector in place and is independent from the top layer of material. So you still have the protector in the right place, while enjoying the freedom and movement of safe Kevlar jeans.
Additionally, you can adjust the protector up and down to position them exactly where you feel most comfortable according to your height.

Are you into black? Want the highest level of safety? Than look no other way, we've just the thing for you! Black classic in a two-piece design ready for an airbag. In our new leathersuit you can enjoy both performance riding on the race track and the casual afternoon ride in jeans.

DRESS LIKE A PRO RIDER!

The materials, cut, and triple-stich sewing technique are based on our experience developing racing suits. At 4SR we do not differentiate between racing and customer suits, so this suit is made of the same quality leather, sewn with the same technology and equipped with the same protectors as the suits of our factory riders in WSBK, BSB or Moto America.

MADE FOR GRINDING THE ASPHALT!

The leathersuit is made of premium 1.2 mm thick cowhide leather and comes equipped with a total of 17 protectors. On the shoulders, elbows, knees and shins you will find comfortable Italian Betac protectors. Panels of memory foam sewn into the areas around the shoulders, collarbones, elbows, forearms, hips, base of the spine, knees and shins, absorb impact during falls and give another level of protection in case the leather is sand trough. The most exposed areas during falls – shoulders, elbows, buttocks and hips – contain extra layer of leather. All this is complemented by black sliders on the shoulders, elbows and knees. The suit can be equipped with a back and chest protector, or one of the airbag vests available on the market.

The pre-curved sleeves, forward-leaning shoulders, well-shaped knees, and seamless stretch in the crotch and underarms allow for a flawless riding position on a sportbike. The narrow sleeve cuffs do not impede wrist movement and allow the use of racing gloves. For greater comfort, the jacket is extended in the back part and can be easily attached to kevlar jeans or leather pants using long or short zipper. The suit is embroidered with 4SR logo and other decorative elements made of suede leather.

Once again, we have made progress in development and we are happy to introduce a new model of the best gloves from 4SR. The Stingray Race Spec racing motorcycle gloves have been created with an emphasis on safety and maximum flexibility. 

Riders often prefer comfort and the feel of their fingers in the gloves over high-level protection, but we all know that this is not exactly ideal, and that is why we have focused on joining these conflicting demands.

The fingers controlling the levers have flexible panels built-in at the joint, which do not resist bending and thus enable sensitive touch control of the brakes and clutch. This reduces pressure on the tendons and minimizes the risk of cramps. The entire glove is anatomically pre-closed for better grip on the handlebars. For maximum comfort, external stitching is used.

The edge of the hand is sturdy, equipped with an Antishock system made of Viscofoam material with a memory effect. Because the pinky finger is hit in the vast majority of falls, it is conjoined to the ring finger to increase its protection.

The palm is usually the part of the glove that must resist abrasion well. Kevlar fibers and stingray skins are also used in the area of the palm. That is then backed by Viscofoam memory foam which protects the shuttle bone. The skeleton of the palm, including the fingers, is made of very fine Pittards leather, which is 2x more durable than kangaroo leather.

To protect the joints, it was necessary to develop a new protector made of flexible material and at the same time resistant to abrasion. The energy of the impact is distributed within the area and partially absorbed by the protector. Additional energy is absorbed by the Viscofoam layer below it. For the glove to fit properly, the dimensions of this protector correspond to the size of the glove

Our motorcycle suits are frequently used at the BSB championship, one of the most dangerous superbike competition. Since the suits are exposed to maximum strain during frequent fall-downs, we ensure the quality protectors are placed correctly.

Race inspired features show up in the form of shoulders, pre-curved arms, 3D lining, articulated knees/sleeves, extension in the arms and more allocation of Kevlar stretch materials.

The grey Kevlar® motorcycle sweatshirt - without a hood, with 2D embroidery 4SR, is fully made using unique Kevlar fabric. Thanks to this structure, it no longer has to be reinforced in other areas like ordinary sweatshirts made of standard sweatshirt fleece fabric. We had the resistance of the abrasion tested on our motorcycle sweatshirt by the German TÜV Rheinland® certification centre, where it passed the EN 17092-4 Level A test (45km / h) without any difficulties.

The grey Kevlar motorcycle sweatshirt with a fluorescent yellow print on the chest is sewn from a unique single-layer Kevlar fabric. This makes it very lightweight and incredibly breathable. In addition, it protects the rider's torso and arms from abrasions and cuts during a fall over its entire surface. Therefore, it does not need to be lined with additional protective layers of Kevlar in selected areas, as is common with motorcycle sweatshirts. The 4SR Kevlar sweatshirt is thin, lightweight, breathable, and durable - simply functional.

Durable

We had the material resistance to abrasion tested at the German certification center TÜV Rheinland, where it passed the EN 17092-4 Level A (45 km/h) abrasion test without any problems. Thanks to its composition, Kevlar provides a strong protective barrier against cuts, punctures, and piercing. It is naturally fire resistant up to 426.6 °C.
