Two very different answers to the same question, "how do I protect my neck if I go over the bars?", sit at the top of our neck brace rankings: the Leatt 6.5 Carbon, our highest-rated brace at a 9.5/10 T&T Score, and the Alpinestars Bionic, sitting further down our list at 7.6/10. The Leatt runs $609.00; the Alpinestars runs $394.95, a real $214 gap that isn't just brand markup. It reflects two genuinely different construction philosophies, not the same brace at two price points.
We compared them on chassis construction, how each is designed to work with a chest protector, and where the extra $214 actually goes.

What Actually Matters at This Price Point
Every neck brace worth considering at this level is built around the same basic goal: limiting how far your head and neck can travel during a crash before it's your spine doing the work instead of the brace. Where these two genuinely diverge is construction philosophy, since that's what determines fit, weight, and how the brace actually behaves under load, not just how it looks on a spec sheet.
Leatt is the brand that effectively created the modern hinged neck brace category, and the 6.5 Carbon is still the version other braces get measured against. Its MaxiWeave carbon chassis is engineered specifically to manage front, rear, and lateral load paths through a single connected structure: the hinge design most riders now picture when they think "neck brace" at all. That structural commitment is a meaningful part of why it's kept its position at the top of our rankings.
Alpinestars didn't copy that hinged-carbon format for the Bionic. It uses Alpinestars' own proprietary construction, which is a real engineering choice, not a budget shortcut. Riders whose body shape or riding position hasn't worked well with the standard hinged-carbon silhouette are exactly who this alternative approach is built for. It's also the more natural pick if you're already deep into Alpinestars' boots or gloves and want a matching-ecosystem setup.

The 6.5 Carbon holds the top spot in our neck brace rankings for the same reason the Moto-10 holds it in helmets: Leatt didn't just refine an existing idea, it built the structural foundation most of the category is still working from. The MaxiWeave carbon chassis keeps the brace light enough to forget about on a long moto while still managing load across three directions at once, which is a harder engineering problem than a single-direction impact pad.
At $609.00, this is a brace for riders who've decided the hinged-carbon approach specifically is what they want, and are willing to pay flagship money for the version of it that set the standard rather than a version that's chasing it.
- Best for: Riders who want the hinged-carbon design the category is built around, from the brand that originated it, and don't mind paying flagship price for it.
- Consider instead if: The $214 premium doesn't fit your budget, or the hinged-carbon silhouette hasn't fit your body shape well in the past.
Alpinestars Bionic

The Bionic isn't trying to be a cheaper Leatt, and that's exactly why it's worth a real look rather than a runner-up glance. Alpinestars built it around their own construction approach instead of licensing or copying the hinged-carbon format everyone else defaults to, which means it's a genuinely different product to try on, not just a different price tag on the same idea.
At $394.95, it lands as a legitimately competitive mid-range option for riders who want real neck protection and either don't need the specific hinged-carbon geometry or have found it uncomfortable in the past. It's also a natural pick if you're already running Alpinestars boots or gloves and like the idea of one brand's fit philosophy across your gear.
- Best for: Riders who want a genuinely different construction approach than hinged-carbon, or who are already invested in the Alpinestars ecosystem.
- Consider instead if: You specifically want the category-defining hinged-carbon design or the higher T&T Score of the 6.5 Carbon.
FAQ: Leatt 6.5 Carbon vs. Alpinestars Bionic
Do I still need a neck brace if I already wear a chest protector?
Yes, they protect against different failure modes. A chest protector or roost guard is built to absorb direct impacts to your torso, while a neck brace is built to limit hyperextension, hyperflexion, and compression of the cervical spine during a crash. Both the Leatt 6.5 Carbon and Alpinestars Bionic are designed to be worn over a compatible chest protector, not in place of one.
Will the Alpinestars Bionic fit over my chest protector the same way the Leatt does?
Both are sized to sit over most adult chest protectors, but fit is never universal across every brand and model. If you already own a specific chest protector, check that manufacturer's fit notes or size chart against the brace before buying, especially if your chest protector runs unusually bulky at the shoulders.
Is the $214 price difference just because Leatt uses carbon fiber?
Carbon fiber construction is part of it, but not the whole story. You're also paying for Leatt's position as the brand that effectively created the modern hinged neck brace category, plus the specific engineering work behind managing front, rear, and lateral load paths in a single carbon chassis. The Alpinestars Bionic isn't a cut-rate imitation of that design. It's a genuinely different construction approach, which is a large part of why it costs less rather than simply being a lesser version of the same idea.
Final Verdict
If you want the neck brace our rankings rate highest and the category-defining hinged-carbon design that comes with it, the Leatt 6.5 Carbon earns its flagship price as the brace most others are still trying to match. If the hinged-carbon silhouette hasn't worked for your body or riding style, or you'd rather stay in the Alpinestars ecosystem for $214 less, the Alpinestars Bionic is a real alternative built on its own engineering approach, not a compromise version of the Leatt.
