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 Matrix 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 Matrix AR. A kangaroo leather suit that pushes your limits. The Ultra Light Matrix 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!
4SR FAIR PLAY
We sew all our suits to one production standard. The highest one. That means, that with 4SR you always wear the best and safest gear we are able to make. Naturally including our patented 4× stitched seam (even asphalt is afraid of it).
RIDING ON THE EDGE? GET YOUR KNEE AND ELBOW READY!
The suit is equipped with Elbow Down TECH elbow sliders. One pair of yellow sliders is included in the purchase; additional color variants can be purchased separately. Of course, there are also highly durable knee sliders.
ZIPPER LOCK is the solution that keeps the suit from sliding down and holds it in place, so you can move freely around the paddock even with the suit unzipped.
