Short answer: buy the Shoei RF-1400if you need a current certification — track days, or simply because you want the most-tested helmet available. Buy the HJC RPHA 11 Pro if you ride on the road and want a light composite sport shell for roughly half the money, and you are comfortable with an older ECE protocol on an outgoing generation.
What makes this comparison more interesting than the usual “just buy the Shoei” is that the HJC wins on the spec most riders actually feel. It is 234 g lighteron the published figures. That is not a rounding error over a six-hour day. The Shoei’s advantages are real but they are mostly advantages on paper — which is exactly where a certification argument lives.

Certification: the real gap, and it is not just Snell
There are two separate things going on here and they get conflated constantly.
First, the Snell line. The RF-1400 carries Snell M2025; the RPHA 11 Pro carries no Snell at all. Snell is the only one of the three certifications on a US helmet shelf that is verified by an independent third party which also pulls production helmets for random re-testing, and its protocol asks the most of a shell on impact energy. Whether you need that is a separate question we answer at length in do you need a Snell helmet— the short version is no for street riding and almost certainly yes on track.
Second, and underrated: the ECE generation.HJC’s US page states ECE 22.05for the RPHA 11, not 22.06. That matters more than the version number suggests. ECE 22.06 added oblique-impact testing that measures rotational acceleration — the mechanism behind a large share of serious brain injury — tested more impact points on the shell, and brought visors and accessories into the approval. A 22.05 helmet was never tested against any of it. Our ECE 22.06 vs 22.05 guide walks through the whole change list.
So on certification the Shoei wins twice: it holds a current third-party rating the HJC does not have, and the HJC’s European approval is a generation behind. If certification is the axis you are buying on, the comparison is over here, and our safest helmets ranking is the page to read next.
Weight: the HJC wins, and the gap is large
1,417 g against 1,651 g.Rider Magazine cites 3 lb 2 oz for a medium RPHA 11 Pro; Shoei publishes 3.64 lb for the RF-1400. That is a 234 g difference in the HJC’s favor, and 234 g on your neck is the kind of thing you notice on hour five of a highway day, not something you need a stopwatch to detect.
Two honest caveats, because the published record is not as tidy as the headline number. Shoei does not state a reference size for its 3.64 lb figure, so we are comparing a stated medium against an unstated one. And webBikeWorld measured an XL RPHA 11 Pro at 1,502 g, so the real gap narrows as the size goes up. Treat 234 g as the best available comparison rather than a precise delta — and read our lightest helmets ranking if weight is the deciding factor, because neither of these is the answer there.
Construction: different philosophies, both composite
Both helmets use a real composite shell rather than the injection-moulded polycarbonate you find lower down the market — see our shell materials guide for why that distinction is worth paying for.
HJC’s PIM+is a carbon, fiberglass and aramid hybrid, tuned for low mass. Shoei’s AIM+ is a hand-laid multi-composite of interwoven fiberglass and organic fibers, and the thing Shoei does that HJC does not at this price is tool the RF-1400 in multiple shell sizes across an XS–3XL range. That is why a small RF-1400 does not feel like a mushroom: the shell itself shrinks rather than being padded out with EPS. The RPHA 11 Pro runs XS–2XL. If you are at either end of the size chart, that is a point for the Shoei that the weight column does not show.
Features: closer than you would expect
Neither helmet has an internal sun visor. The RF-1400 does not have one because Shoei would rather you swapped to a tinted shield; the RPHA 11 Pro simply does not have one. Both are Pinlock-ready, and in bothcases the insert is a separate purchase — see stopping a helmet fogging for why we treat that as real money rather than an optional extra.
The HJC’s useful feature is RapidFire II, which makes a shield change a ten-second tool-less job — and given that a tinted shield is how you solve the no-sun-visor problem on either helmet, it is a more relevant advantage than it looks. Shoei’s useful feature is the CWR-F2 shield with vortex generators, aimed squarely at wind noise, which is the complaint riders actually voice most often. Neither maker publishes a verifiable noise figure and no independent body measures helmet noise, so we rank on the design intent and say so — our quietest helmets page explains why nobody can honestly rank by decibels.
The generation question
One more thing to know before you spend money, because it changes how you read the price. The RPHA 11 Pro is the outgoing generation.HJC has launched the RPHA 12 above it on an ECE 22.06 certification and a revised PIM EVO shell. The 11 Pro is still widely stocked and distinctly cheaper, and the whole value case is that gap — you are buying last year’s flagship at a discount, which is a perfectly good thing to do, as long as you are doing it deliberately. The RF-1400 is current.
There is also an Amazon-specific wrinkle worth stating plainly: as of our last live listing check the plain PIM+ RPHA 11 Pro was no longer listed on Amazon, and the complete-helmet listing our buy button resolves to is the Carbon Littcolor option. Same RPHA 11 Pro shell family, same HJ-26 shield, so the specs here hold — but you should know which helmet you are clicking through to.
The spoiler: neither of these may be the answer
If the argument that moved you is the weight, the honest thing to tell you is that the AGV K6-S beats both. A carbon-aramid shell at a published 1,255 g— 162 g lighter than the HJC and 396 g lighter than the Shoei — with DOT and ECE 22.06, and a 190-degree Ultravision eye port. It has no internal sun visor either, and it sits at premium money rather than the HJC’s mid tier.
We put it on this page rather than leaving it out because a two-helmet comparison that hides the helmet which wins both arguments is not a comparison, it is a sales page. If you want that one against the Shoei directly, we have RF-1400 vs K6-S.
The decision, in four lines
Track days, or you want the most-tested helmet:RF-1400. Snell M2025, current generation, multiple shell sizes. Check your organizer’s tech rules first — our track-day ranking is built around that requirement.
Road riding, composite shell, least money: RPHA 11 Pro, knowingly. It is the better value in this pair and the lighter helmet.
Weight is the whole point: AGV K6-S, which gets you 22.06 as well.
Either way: get the sizing right before the badge. Both of these are intermediate-oval-friendly shells — though HJC publishes no head shape for the RPHA 11 Pro at all, which our head shapes guide explains how to work around.
