A motorcycle suite made from kangaroo leather used to be a privilege for professional racers to wear. Its minimum weight was loved by riders who were slowly losing strength, as well as engineers who were increasing the maximum speed of the machine by tenths. You now have a chance to experience that feeling of lightness as well. We present you with the lightest suit in the 4SR collection.

Easy and fast, you're now Airbag Ready! Thanks to the unique cut and placement of accordion stretch panels, you can use several variants of standalone airbags available on the market. Our stitching and materials remain and will always remain 100% the same as our factory racers suits.

The price includes knee and elbow sliders, internal protectors, removable chest and back protectors, double hip and coccyx protection and all from reputable brands. We have 18 ergonomically placed protectors, the most used in any mass-produced 1pc leather suit.


   We have also developed a simple and effective solution for holding up your leathers between track sessions, 4SR's Zipper Lock system will effectively hold the upper half of your suit out of the way.
