Why 4SR

Production functionality, not price or design, always comes first

In 4SR we produce functional and safe products. Price and design are important factors in our customers' decision-making, we know, but it is product functionality that we pay particular attention to. In our assortment you will never find mere designer fads; each detail has to have a reason.


Development and experience from the racing environment

Where best to test new protectors or a new racing suit in real-life conditions? In racing conditions, of course. And that is the reason why we cooperate with experienced racers in our development. For example, our main test rider Matěj Smrž has 20 years of experience in top races.



Cooperation with leading protector producers

4SR products always have to meet and exceed the highest standards of safety. We therefore do not manufacture our own protectors, but rather use the best in each given segment, made by specialized producers. We always look at the quality of protection of the rider, provided by the protectors.
As the only manufacturer in the Czech Republic, we use protectors from leading European producers Betac and Pro-Life.


It is the suit, not the certificate, that protects the rider (very low certification requirements)

A customer who wants a top-quality motorcycle suit should realize that his/her safety is in the hands of a specific product, not certification. CE certification under EN 1621-1 provides standards so low that it can be met even by products of a lower quality. 4SR products highly exceed the limits specified by that standard. That is why they are used in World Cup races, too.

The same products for customers and for competitive riders

It doesn't matter whether you're a street racer or a World Cup rider. You're equally important to us in 4SR. 4SR products for our customers are made from the same materials, sewn with the same technology and equipped with the same protectors as the products for our racers.


Why do most Czech national team riders cooperate with 4SR and not with other brands?

Only a high-quality, well-tested manufacturer can meet the tough conditions of races worldwide. Product quality and functionality come first here. The riders in motorcycle sports risk their lives in every race, and therefore they only trust the best. Long-term, repeated cooperation is the proof.


Why doesn't  4SR use hard exterior protectors of metal?

We can use metal protectors very easily. However all protectors used on 4SR products must be subjected to load testing. Unfortunately, no metal protectors have passed such tests and, therefore, cannot be used on 4SR products.

Why are our products not made from kangaroo leather

We can sew a suit from kangaroo leather, lighter than our existing suits, but our experience with falls in WSBK, IDM and Moto GP clearly shows that kangaroo leather is not the safest material for the production of suits. Strength and flexibility are more important than weight, and that is why our suits are so resistant.
