Ranked #5 in Best Motorcycle Helmets Under $300

HJC IS-MAX II Modular

3.8

2 sources1 derived

Around $200 bought the HJC IS-MAX II (now discontinued, per Billys Crash Helmets, though leftover stock may still turn up), the best modular (flip-up) helmet in this group, with a smooth-opening chin bar, an integrated drop-down sun visor and a Pinlock-ready shield. webBikeWorld rated it 4/5 A Good Buy and Motorcycle.com scored it 87.5/100, both noting it offers more than almost any modular at the price and comes surprisingly close to lids costing three times as much. webBikeWorld counts it as lightweight, though Billys Crash Helmets calls its weight about average for a modular, and it is convenient for touring and commuting. The sun-visor spring feels flimsy and it is not the quietest flip-up, but for an affordable flip-up that covers several jobs, the IS-MAX II is the pick.

Strengths

— Smooth-operating modular chin bar that flips up easily with a gloved hand
— Integrated drop-down sun visor doubles as eye protection without swapping shields
— Lightweight per webBikeWorld at around 3.8 lb (Billys Crash Helmets rates it about average for a modular)

Watch-outs

— Drop-down sun visor spring feels weak and may not last long-term
— webBikeWorld found some minor fogging in humid conditions despite venting
— Not the quietest modular at this price point, per Billys Crash Helmets

Scorpion EXO-R420

4.1

2 sources1 derived$150as of May 26

Safety comes first with the Scorpion EXO-R420, one of the rare sub-$200 full-face helmets carrying Snell M2015 certification on top of the mandatory DOT approval. webBikeWorld rated it 4/5 and RevZilla owners 4.5/5 across more than 800 reviews, with praise for a genuinely deep feature set: EQRS emergency release, the EverClear anti-fog shield, the tool-free Ellip-Tec II shield swap and efficient ventilation. For maximum crash certification at a low price, the EXO-R420 sets the benchmark.

Strengths

— Carries Snell M2015 certification on top of DOT, rare at this price, per Billys Crash Helmets
— 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, per Billys Crash Helmets

Watch-outs

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

How they stack up

HJC IS-MAX II Modular

The HJC IS-MAX II is the only modular (flip-up) helmet in this group, offering convenience the fixed-chin Bell Qualifier DLX MIPS, Scorpion EXO-R420 and HJC C10 cannot, and a more road-focused design than the adventure-oriented Bell MX-9 Adventure MIPS. Its integrated sun visor is a feature only it and, indirectly via Transitions, the Qualifier offer. It is DOT-rated only, lacking the MIPS of the two Bell helmets and the Snell of the Scorpion.

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.
