Ranked #5 in Best Motorcycle Helmets Under $300

HJC C10

4.2

$129.99as of May 29

The HJC C10 is the budget champion of this group, a sub-$100 full-face helmet that meets the latest ECE 22.06 safety standard, a rarity at the price. Reviewers call it the best value motorcycle helmet they have tested; RideApart, MCN and RevZilla all praise its comfort, exceptional ventilation and build quality that feels worth far more than its cost. It is all-day comfortable with plush cheek pads and a lightweight shell. The first visor detent lets in debris and it fogs without a Pinlock, but for a rider who wants a genuinely safe, comfortable full-face on the tightest budget, the C10 is unbeatable.

Strengths

— Meets the latest, most demanding ECE 22.06 safety standard plus DOT
— Exceptional ventilation that flushes heat well for a full-face helmet
— All-day comfortable liner with plush cheek pads that resist flattening

Watch-outs

— First visor detent opens wide enough to let in bugs and debris
— Fogs in humid conditions without the optional Pinlock insert
— Padding is not adjustable for fine fit tuning

Higher ratedRanked #2 in Best Motorcycle Helmets Under $300

Scorpion EXO-R420

4.4

$150as of May 26

The Scorpion EXO-R420 is the safety-first pick of this group, the rare sub-$200 full-face helmet to carry Snell M2015 certification alongside the mandatory DOT approval. webBikeWorld rated it 4/5 and RevZilla owners 4.5/5 across more than 800 reviews, praising the genuinely impressive feature set: EQRS emergency release, the EverClear anti-fog shield, the tool-free Ellip-Tec II shield swap and efficient ventilation. The trade-off for Snell-grade protection is weight; at nearly 3 lb 14 oz it is the heaviest helmet here. But if maximum crash certification at a low price is the priority, the EXO-R420 is the benchmark.

Strengths

— Carries Snell M2015 certification on top of DOT, rare at this price
— Ellip-Tec II tool-free shield swap with a secure center-locking latch
— EQRS emergency cheek-pad release for safer helmet removal after a crash

Watch-outs

— Heavy at around 3 lb 14 oz for a size large polycarbonate shell
— Standard shield is not Pinlock-ready
— Shell can lift slightly at sustained highway speeds above 60 mph

How they stack up

HJC C10

The HJC C10 is the budget pick of this group, costing roughly half the Bell Qualifier DLX MIPS or Scorpion EXO-R420 while still meeting the latest ECE safety standard. It lacks the MIPS of the two Bell helmets and the Snell certification of the Scorpion, and it is a fixed full-face rather than a modular like the HJC IS-MAX II or an adventure helmet like the Bell MX-9 Adventure MIPS. Its certification is the newest crash standard of any helmet here.

Scorpion EXO-R420

The Scorpion EXO-R420 is the safety-maximalist pick, the only helmet here with Snell certification on top of DOT, where the Bell Qualifier DLX MIPS instead offers MIPS and the HJC C10 carries the latest ECE rating. It is a pure street full-face, not an adventure helmet like the Bell MX-9 Adventure MIPS or a modular like the HJC IS-MAX II. Its main downside versus the lighter Qualifier is weight, the price of its Snell-grade polycarbonate shell.
