a decent motorcycle jacket is always equipped with approved shoulder and elbow protectors. Motorcycle pants are almost always equipped with approved knee protectors as standard. Of course anyone can upgrade their motorcycle clothing with 'better' protectors afterwards. Almost every motorcycle jacket can be provided with a CE approved back protector, this is very important to prevent injury to the back protectors.
Separate back protectors have been developed especially for sports and circuit use, which are approved according to the CE Level 1 or the better CE level 2 standard. To complete the protection, you can use an approved hard chest protector. Separate chest protectors can be integrated with Alpinestars motorcycle jackets. Of course the knee sliders on motorcycle suits can also be replaced!
