Nucleon Flex Pro represents Alpinestars’ premium CE Level 2 protective armor designed for motorcyclists seeking superior impact protection without sacrificing comfort or mobility. I’ve tested these protectors extensively in various riding conditions, and they deliver remarkable performance advantages over traditional motorcycle armor.
Nucleon Flex Pro | Delivers | Superior Protection
Nucleon Flex Pro protectors utilize advanced TPR (thermoplastic rubber) construction with a geometric pattern that maximizes impact absorption. The protectors achieve the coveted CE Level 2 certification while maintaining exceptional flexibility and a low-profile design. This represents a significant advancement over the previous Flex Plus armor that offered CE Level 1 protection.
I crashed at moderate speed wearing Nucleon Flex Pro knee protectors last summer, and the impact dispersion was noticeably better than with my previous armor. The geometric shape creates a sophisticated crush zone that absorbs and distributes energy throughout the protector instead of transferring it directly to your body.
The asymmetrical design ensures each protector fits perfectly on either the left or right side of your body. You’ll find clear left/right markings on each piece to ensure proper placement. I once installed them incorrectly and immediately noticed the awkward fit – the body-specific contours make a significant difference in both comfort and protection.
Nucleon Flex Pro | Features | Rider-Focused Design
Nucleon Flex Pro armor incorporates multiple design elements that enhance both protection and comfort:
- Highly flexible construction that moves naturally with your body
- Low-profile shape that fits comfortably under riding gear
- Geometric pattern that maximizes airflow and ventilation
- Asymmetrical left/right specific design for anatomical fit
- Available in multiple sizes to accommodate different body types
The AMT-10R jacket pairs perfectly with these protectors, creating a comprehensive protection system. I’ve worn this combination on long summer rides, and the breathability made a noticeable difference compared to traditional armor systems that trap heat and moisture.
The protectors maintain their protective qualities without the bulk and weight associated with traditional CE Level 2 armor. This creates a protection system that feels less restrictive during long rides while still providing confidence-inspiring impact resistance.
Nucleon Flex Pro | Includes | Comprehensive Body Coverage
Alpinestars offers Nucleon Flex Pro protection for multiple body zones:
| Protection Zone | Key Features | Available Sizes |
|---|---|---|
| Shoulder | Asymmetrical design, CE Level 2 | Small/Large |
| Elbow | Contoured fit, Enhanced flexibility | Small/Large |
| Knee | Geometric ventilation, Impact dispersion | Small/Large |
| Chest (CI) | Core protection, Breathable design | Universal |
The Protection Vest model integrates multiple Nucleon Flex Pro protectors into a single garment for comprehensive upper body protection. This creates a versatile protection system that works across multiple riding styles without compromising safety or comfort.
When upgrading from older Alpinestars jackets, you might notice these protectors are more compact than previous generations. This lower profile design might create extra space in armor pockets of older jackets – something to consider when upgrading your protection system.
Nucleon Flex Pro | Represents | Protection Evolution
Nucleon Flex Pro armor demonstrates Alpinestars’ commitment to advancing rider protection technology:
The protectors build upon the foundation established by the Flex Plus line while elevating protection to CE Level 2 standards. This evolution maintains the comfort and flexibility riders appreciated in the previous generation while significantly enhancing impact resistance.
The comprehensive protection system integrates seamlessly with Alpinestars’ broader range of motorcycle gear, including their Tech-Air airbag systems. This creates multiple layers of protection that work in harmony to maximize rider safety in various impact scenarios.
Nucleon Flex Pro technology represents a significant advancement in motorcycle protection, delivering genuine impact resistance without compromising on comfort, flexibility, or ventilation.
