Alpinestars RK-7 Plasma Black Red Knee Braces

Safety and approval

The knee braces are CE certified level 1 to EN 1621-1:2012, as stated by the manufacturer. Always check the label of the product you receive and make sure the hinges work without forcing the joint.

Fit and sizes

This product is available in sizes S. To choose your size, measure your chest (or your leg, for knee braces) and compare it with the manufacturer’s size chart; if you are between two sizes, contact us before buying and we will help you choose the most suitable one, taking into account what you will wear over and under it.

Who it is for

These knee braces are designed for motocross and off-road riding, in training and racing. The adjustable extension stops let you tailor the support to your needs and riding style.

Care and maintenance

Clean the product with a damp cloth and mild detergent, without bleach. Where applicable, remove the protectors before washing and let it air dry away from direct heat. Check straps, buckles and seams regularly and replace the protectors after a significant impact. Rinse off sweat residues after a hot session to keep the fabrics fresh.

Why choose it

A motocross protector only works if it stays in the right place while riding. That is why adjustability, low weight and ventilation matter: the best protection is the one you are happy to wear for the whole session, from the first moto to the last.

If you need help choosing the size or pairing the protector with the rest of your gear, our team will gladly answer your questions.

A practical tip: try the protector on with the clothes you will really wear and move your arms, torso and legs in riding positions. It must not shift or restrict movement, but stay firmly over the areas to protect. A correct size is essential so that the protection works in the right place in a fall. Check that straps and buckles close without twisting before every ride.
