The Alpinestars SX1 are a light and vented knee guard, designed for those who are looking for a knee protection but not as sophisticated as the protectors used by the offroad professionals.
Construction and materials
The chasis of the Alpinestars SX1 is composed by two protectors linked thanks to two hinges, that allow the movement of the knee. These parts are combined by a kneecap protector. This piece is made with semirigid TPU and it has an ergonomic design. Around the kneecap protector we find foam that offers an integral protection on this critical area.
The two mobile protectors offer a correct protection in the area of the thigh and shin, thanks to the high performance polymers, which are combined with an internal Polyurethane foam for an optimal absorption of the hits. The touch is nice and its orifices allow a proper ventilation.
Adjustments and installation
For the protector’s adjustment, we have two flexible straps, that can be fixed through Velcro adjustments, mantaining the protector on its place at all time, avoiding unwanted movements. As a detail, the Vlecro straps have a neoprene finish, helping us on a better adjustment. we also find the “right” and “left” labels, that will help us to fit easily the knee protectors on our legs.
With these knee protectors, Alpinestars is offering an excellent choice for those who practise motocross or enduro but not as a professional level. The Alpinestars SX1 are homologated as motorcyclist protection and offer a very good value for money.
