Over the years, I’ve strapped on countless helmets, riding everything from twisty backroads to long highway hauls, so I was thrilled to test the LS2 Advent X Modular Helmet. Fresh out of the box, its sleek, pearlescent white finish caught my eye, and I couldn’t wait to toss it into my routine on my trusty bike.
After logging 300 miles across a couple of rides, I’ve got a real feel for this one—lightweight, versatile, and packed with thoughtful touches. It’s hands-down the quietest modular I’ve owned, and the quality rivals expensive helmets I’ve tried before. If you’re looking for a quiet full face motorcycle helmet that doesn’t break the bank, this one’s definitely in the conversation.
Still, a few quirks popped up during my time in the saddle. I’m sold on a lot of it, but not everything’s perfect. Here’s my take, straight from my own experience, with the features and what I loved or wrestled with on the road.

My Pros and Cons About the Model
Pros I Loved
- Super Quiet: In my opinion, this is the quietest modular I’ve worn! Wind noise barely bugged me, even at 65 mph—way better than my old Simpson or Schuberth.
- Light & Solid: At 1,600g, it’s a breeze to wear. The KPA build feels top-notch, rivaling helmets I’ve paid double for, and I love the quality.
- Flip-Up Bliss: The 180° chin bar flips back smooth with one hand—no wind-catching sail effect! Kept me cool at stops and secure at speed.
- Comfy Fit: Cheek pads were tight at first, but after two rides, they molded perfectly to my medium-sized head. No hot spots, just cozy all day.
- Visor Wins: The optically correct shield is crystal-clear, and the built-in sun shade saved me on bright rides—super handy with an easy left-side switch.
- Bonus Goodies: Came with a Pinlock insert, dark shield, and a backpack bag! Changing shields was a cinch, too, in my experience.
- Bluetooth Ease: My Cardo Pack Talk Bold slid into the speaker pockets like a dream—sound’s great, and setup was a breeze.
Cons I Noticed
- Noisy at Speed: Despite being quiet, past 65 mph, wind noise drowned my Sena EVO. My ears hummed after long rides—earplugs didn’t fully cut it.
- Sizing Woes: I ignored reviews and regretted it! My medium was tight, pressing my forehead and neck. I swapped for a larger size—trust me, size up!
- Chin Strap Struggles: The ratchet strap’s short and tricky to secure blindly. Mine arrived twisted, and it felt choke-y until I got the hang of it.
- Bulky Look: It’s wider than my Simpson—felt like a “Spaceballs” head! I nearly returned it, but the features won me over, barely.
- Liner Hassle: The innermost liner’s attached, making my J&M mic install a pain. Took some fiddling to unsnap and fit it right.
- Shield Sync Issue: Raising the chin bar lifts the shield automatically—annoying! It pops up again when closing, which threw me off on rides.
Hands down, I’m a fan of the LS2 Advent X. It’s a steal for the price—light, quiet, and versatile, with a fit that hugged my head after breaking in.
The flip-up design and sun shield made my rides a joy, especially on hot days at red lights. Sure, the noise at highway speeds and funky strap bugged me, but in my book, the positives shine brighter. Plus, it helped me bust some of my own helmet noise myths—you don’t always need the most expensive helmets to get solid wind reduction.
If you’ve been comparing motorcycle helmet types and wondering whether a modular can be as quiet as a full-face, this one proves quieter helmets can come from the modular world too
For new or seasoned riders, I’d say grab one—size up, though! It’s my new favorite, and I’m already itching to roll out and flaunt this beauty again!
