Strengths
- ECE 22.06 certified at a budget price — the newest standard, rarely found this cheap
- Built-in drop-down sun shield, which most premium full-faces here don't have
- Pinlock-ready face shield and a rear spoiler with flow-through ventilation
Trade-offs
- Kinetic Polymer Alloy shell is heavier and less premium than a composite lid
- Fit and finish are good for the price, not flagship-grade

The budget helmet that overdelivers
Most budget helmets pick one nice feature to stand out. The LS2 Stream II stacks several: DOT and ECE 22.06 certification, a built-in sun visor, a Pinlock-ready shield and LS2’s AREM rotational-energy management—all at a price around $150. That combination is why it’s our top overall pick in the budget ranking and a strong option for a first helmet.
Certification at a budget price
The standout is the ECE 22.06 rating. That’s the current European standard, independently tested, with rotational and multi-point impact testing that the older 22.05 didn’t require—and it’s rare to find it this cheap. Paired with DOT and LS2’s AREM system (which addresses rotational forces), the Stream II’s protection story is genuinely strong for the money. Our safety-ratings guide explains what 22.06 tests.
Features you usually pay more for
The built-in drop-down sun visor is the everyday highlight—most premium full-faces (the RF-1400, the K6 S) don’t have one, and here it’s standard. The face shield is Pinlock-ready to kill fogging, and a rear spoiler adds flow-through ventilation. For a rider who wants a sun visor without paying for a modular, that’s a real draw.
The honest trade-off, and who it’s for
The compromise is the Kinetic Polymer Alloy shell: heavier and less premium than a composite lid, so more neck fatigue on long days, with good-for-the-price rather than flagship fit and finish. That’s the right corner to cut—the weight is a comfort issue, not a safety one. Buy the Stream II if you’re a budget-minded commuter or new rider who wants ECE 22.06 and a sun visor without overspending. If you want a lighter shell, you’re into composite-helmet money, and the full-face ranking has those options.
Frequently asked questions
Is the LS2 Stream II ECE 22.06 certified?
Yes — and that's the headline. The Stream II carries ECE 22.06, the newest European standard with rotational and multi-point impact testing, plus DOT, at a price around $150. Finding 22.06 certification this cheap is genuinely unusual, and it's the main reason the Stream II is our top overall budget pick.
Does the LS2 Stream II have a sun visor?
Yes — it includes a built-in drop-down sun shield, which most premium full-faces in our ranking don't. Combined with a Pinlock-ready face shield, that makes it a genuinely well-featured budget helmet: you get sun and fog handled without swapping shields.
What's the catch with the LS2 Stream II?
Mostly weight and materials. The Kinetic Polymer Alloy shell is heavier and less premium than a composite or carbon lid, so it's more tiring on a long ride, and the fit and finish are good-for-the-price rather than flagship-grade. The core protection (DOT plus ECE 22.06) is not where the compromise is.
