Like any other garment we produce at 4SR, the GTS Lady 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 motorcycle 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.

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.
