Frequently asked questions Hide FAQs
What types of knee protection are available in this MX collection?

This motocross knee protection collection includes hard-shell knee guards, soft knee braces, and hybrid protection systems. Hard-shell protectors offer maximum impact resistance with CE-certified armor, while soft braces provide compression support and flexibility for extended riding. Hybrid designs combine rigid external shells with internal padding for comprehensive protection against impacts, abrasion, and hyperextension during motocross and off-road riding.
Are these MX knee protectors compatible with motocross boots and pants?

Yes, the knee protectors in this collection are designed to integrate seamlessly with motocross boots and pants. Most models feature low-profile designs that fit comfortably under or over MX pants without restricting movement. The anatomical shaping ensures proper alignment with boot tops to eliminate gaps in protection. For optimal compatibility, pair with MX boots and MX pants from Alpinestars for a complete protection system.
How do I choose the right size for MX knee protection?

Proper sizing ensures both protection and comfort during motocross riding. Measure the circumference of your leg approximately 15cm (6 inches) above the center of your kneecap while standing. Compare your measurement to the size chart provided for each knee protector model. The fit should be snug without restricting blood flow or movement—you should be able to fully bend your knee without the protector shifting position. Adjustable straps on most models allow fine-tuning for a secure, personalized fit throughout your ride.
What safety certifications do these motocross knee protectors meet?

Alpinestars MX knee protection meets rigorous international safety standards, with many models featuring CE certification under EN 1621-1 for impact protection. This certification ensures the armor has passed standardized tests for energy absorption and impact resistance. Racing-grade models may also comply with FIM homologation requirements for professional motocross competition. Each product listing specifies the exact certifications, ensuring you select knee protection that meets your riding discipline's safety requirements.
Can I wear MX knee protectors for other off-road activities besides motocross?

Absolutely. While engineered specifically for motocross, these knee protectors are highly versatile for various off-road activities including enduro, trail riding, hard enduro, and recreational dirt biking. The protection technology and ergonomic design translate effectively across disciplines that involve similar impact risks and riding positions. Many riders also use MX knee guards for mountain biking downhill and BMX racing. Explore our complete off-road protection collection for discipline-specific options.
