Make Your Track Days Better
Since 2007
An ultra-light, maximally perforated, and super safe suit worn by professional racers can be yours too. On a bike, it’s all about freedom, movement, and feel. The Racing Ultra Light Pista AR suit gives you all of that without compromise—and it’s also ready for an airbag.
Entering the world of motorsport, where milliseconds determine success and style is part of a rider’s identity, comes the Racing Ultra Light Pista AR.
The Ultra Light Pista AR is designed for maximum freedom of movement and rider performance in every situation. A wide range of motion is achieved by the seamless aramid stretch.
The Airbag Ready® system gives you the choice: either you ride with a complete set of 18 ergonomic protectors, or you remove the chest and back protector and wear an airbag under the suit. Fast and simple—you're ready. Airbag Ready!
Every 4SR suit is made to the same uncompromising production standard—the highest we can achieve. No shortcuts. No lower tiers. When you wear 4SR, you wear the safest and most advanced gear we know how to make, trusted by our factory riders.
This commitment includes our patented 4× stitched safety seam in high-impact zones — so strong that even asphalt is afraid of it.
The suit is equipped with Elbow Down TECH® replaceable elbow sliders. One pair of white sliders is included; additional colour options are available separately. Naturally, highly durable knee sliders are also included for maximum confidence on track.
ZIPPER LOCK® keeps the suit securely in place when unzipped, allowing free movement in the paddock without the suit sliding down

We really understand how important it is to have a racing suit that fits perfectly.
This Is Racing | Hannes Soomer & 4SR
We selected some of our products, sent them to the German certification centre TÜV Rheinland® and awaited the test results.
Majority of companies use Denim and aramid fabric that reinforces exposed areas. 4SR Kevlar® jeans are different. Here is why...
Are you looking for a top-class racing suit that you can use with or without an Airbag? Our suits are compatible with most Airbag Systems.
