4SR USA

Our one-piece racing suits are manufactured on a custom basis and are made to fit.
We really understand how important it is to have a racing suit that fits perfectly. That´s why we try to consider the needs and physical proportion of each racer. All of this goes hand in hand with color combination and the overall design, which can be done in any color combination and style. Specifically, even with sponsor logos, names and numbers. All details can be produced in printed form, leather logos, embroidery or laser burning.
   

Contact us at individual@4sr.com and you will immediately receive graphical materials and supplementary information. We are looking forward to hearing your ideas! 

 

We caught up with 4SR racers, to ask them 2 questions - "Why do you race in the British Supersport Championship & What made you choose 4SR leathers?"
Watch the full videos in Video  tab below to find out why!

Please note that we can't ship the suit to California.

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.
