Championship-Tested Motocross Body Protectors

Alpinestars® MX body protectors are engineered for the intensity of motocross, supercross, and off-road racing. The range spans roost deflectors, CE-certified chest and back protectors, integrated vests, and rib coverage that shield vital zones from debris and crash forces. Hard-shell plates combine with energy-absorbing foams to disperse impact while the ergonomic architecture preserves freedom of movement. Low-profile silhouettes integrate cleanly under or over a jersey so you can stay focused on throttle control, braking points, and traction.

 

Ventilation, Mobility, and All-Day Comfort

Heat management is essential from the first gate drop through the final lap. Extensive perforation, channelled airflow, and moisture-wicking liners help regulate temperature in hot and humid conditions. Articulated panels, soft-edge bindings, and flexible linkages promote natural motion over whoops and ruts. Adjustable shoulders and waist straps dial in stability so the protector remains centered when you are standing, seated, or weighting the outside peg.

 

Certified Impact Coverage and Modular Options

Select models carry EN 1621-3 for the chest and EN 1621-2 for the back in Level 1 or Level 2 ratings, indicating transmitted-force thresholds. Roost-focused shells may reference EN 14021 for stone deflection. Choose streamlined under-jersey armor for minimal bulk or hybrid hard-shell systems for extended coverage. Modular shoulder and side-rib panels let you scale protection for speed, terrain, and event format without compromising balance or bike feel.

 

Under-Jersey and Over-Jersey Integration

Designed for versatile setups, slim protectors slide beneath a jersey for a locked-in feel, while over-jersey roost deflectors maximize airflow and quick changes. Low collars, contoured shoulders, and thoughtful plate cutouts help maintain clearance for neck braces and hydration packs where applicable. Quick-release buckles and elasticated straps simplify on-the-fly adjustments and reduce lift at speed.

 

Durable Construction and System Pairing

High-impact polymers, abrasion-resistant shells, and robust stitching deliver durability through repeated motos and post-ride cleaning. Smooth inner surfaces reduce hot spots, while removable components streamline maintenance after muddy sessions. Build a complete MX system by pairing torso protection with certified MX helmets, track-ready MX boots, and complementary MX protection for head-to-toe coverage.

 

Ride with confidence backed by decades of competition-driven development. Alpinestars® MX body protectors combine advanced impact management, airflow, and precise adjustability so you can push your pace, maintain control, and stay protected from practice laps to the checkered flag.
Frequently asked questions Hide FAQs
What’s the difference between a roost deflector and a CE-certified MX body protector?

Roost deflectors are primarily designed to shield against roost (stones and debris) and light impacts, while CE-certified chest/back protectors are engineered to attenuate crash energy to defined standards for impact protection.

Protection TypePrimary PurposeCertificationTypical Wear
Roost DeflectorDeflects debris and minor contactsOften EN 14021 (stone shield) or un-certifiedCommonly worn over a jersey; very ventilated
Chest/Back ProtectorImpact energy absorption in a crashEN 1621-3 (chest) / EN 1621-2 (back), Level 1 or 2Frequently worn under a jersey for close-to-body fit

If you ride tracks or more technical terrain, many riders choose CE-certified chest and back protection for higher impact attenuation, sometimes paired with a lightweight roost shell depending on conditions.
Should I wear my MX body protector under or over my jersey, and how should it fit?

Slim, CE-certified chest/back protectors are typically worn under a jersey for a stable, close-to-body fit; roost deflectors are often worn over a jersey for quick on/off and maximum airflow. Either approach is valid as long as the protector stays centered, doesn’t ride up, and doesn’t restrict arm or head movement.

Size by your chest circumference and torso length, then fine-tune straps so the sternum, ribs, and spine are covered without gapping. In riding position, the protector should not contact your helmet, interfere with a neck brace (if used), or shift during braking and landings.
Which safety standards apply to MX body protection, and what do Level 1 and Level 2 mean?

Off‑road stone shields may reference EN 14021, which focuses on roost and debris deflection. Impact‑absorbing protectors typically carry EN 1621-3 for chest and EN 1621-2 for back. Each of these has Level 1 and Level 2 ratings—Level 2 indicates lower transmitted force (higher impact attenuation) under standardized tests.

Choose the level based on your risk tolerance and riding style: Level 2 offers more impact reduction and may be slightly heavier or less ventilated than Level 1. Always verify the label or product description for the exact standard and level.
Can I use a chest/back protector with a neck brace or a hydration pack?

Yes. Many MX body protectors are designed with neck‑brace and pack compatibility in mind. Look for adjustable shoulders, low‑profile collars, and modular panels so the brace can sit correctly on your shoulders and the backplate can accommodate a hydration bladder without creating pressure points.

Test the full setup on the bike to confirm the brace contacts the intended surfaces and that pack straps do not shift the armor. For neck support options, explore our neck protection collection; for additional torso options, see MX chest protection.
How do I clean and care for MX body protectors?

Remove any soft inserts if possible, close straps, and rinse off dirt first. Hand wash fabric components in cold water with mild detergent; wipe hard shells with a damp cloth. Do not use bleach, solvents, or fabric softeners.

Air dry away from direct heat and sunlight, and reassemble only when fully dry. Inspect after any significant crash—replace protectors that show cracks, crushed foam, or deformed panels to maintain impact performance.
