Things to consider before buying


HJC has prevailed with regards to offering a cap that fights at a surprisingly high level. Notwithstanding being perhaps the most costly contributions from HJC, the RPHA 70 ST is a sub $400 helmet and offers astounding quality and worth in the value range. 

Quality and Safety 

There’s a full carbon fiber variant of the RPHA accessible. Be that as it may, most of the RPHA 70 ST range is produced using what HJC calls their Premium Integrated Matrix in addition to or PIM for short. That is a mind-boggling 6 layer composite overlay, including layers of carbon, glass fiber, and aramid (kevlar) intended to offer great effect resistance while being lightweight. 

Sway resistance is just a single portion of the condition regarding a powerful accident protective cap (with energy assimilation being the other half). On the off chance that you take a gander at the SHARP security tests covering HJCs, you can see they have a mishmash of results. Their average score across completely tested HJC protective caps is just more than 3 out of 5. And keeping in mind that the composite-shelled FG-ST scored a most extreme five, their top-of-the-reach RPHA 11 just dealt with a modest 3/5.

Nonetheless, it merits recollecting that the most significant thing with any head protector is to get one that fits right – a SHARP one-star cap that fits impeccably will secure you better than a five-star cap that is a helpless fit. 

Proceeding onward from cap shell and stun ingestion execution, the RPHA 70 ST has some other helpful wellbeing highlights. Foremost among these is the crisis fast expulsion cheek cushions (EQRS) – intended to help eliminate the protective cap by crisis staff. There are likewise old-fashioned twofold ring fasteners – it very well may be an old-style approach to fasten a head protector; however, they’re protected as houses and a must on the off chance that you need to take your cap on the track. The RPHA 70 will likewise accompany both an enemy of haze embed (however, it is anything but a Pinlock) and against a mist-covered drop-down sun visor. 

Having a basic sun visor can be exceptionally valuable. Also, having it against haze covered ought to be truly valuable as well. However, we’ll need to keep a watch out if the covering’s, in reality, any great: it’s one thing saying it’s enemy of haze covered yet. Altogether another if it functions admirably! 

Comfort and sizing

The HJC RPHA 70 estimating goes from XXS to XXL (that is size 52/3 through to 62/3). Within, you’ll track down the typical removable/launderable covering, and you’ll additionally discover a glasses section to help to ride in shades and glasses more agreeable. It additionally considers every contingency as far as dynamic textures as well. It is moisture-wicking, its enemy of bacterial, smell decreasing and snappy drying. 

It doesn’t contain a portion of the opposition’s chic materials, yet it marks all the cases, and proprietors figure that it’s a truly agreeable cap. A couple of thought it was all too close at first, however, said that it breaks in rapidly and, presently it has, they love the solace even on long rides.

Highlights and advantages

Noise Isolation 

It’s uncommon that we run over an especially calm protective cap. Yet, the word on the RPHA 70 ST is, by all accounts, pretty consistent. This is one helluva calm cap. It seems like HJC has worked some speculative chemistry with the air and cushioning because not exclusively is it allegedly probably the quietest protective cap around. However, that clamor doesn’t appear to increment in any event when the vents are open. 


HJC has done a great deal of work on making the RPHA 70 ST extraordinary compared to other venting protective caps. Two or three jawline vents; the top primary vent coordinates air up onto the rear of the safeguard and around the jaw region. The upper vent is not difficult to work utilizing a slider in the standard situation outwardly of the cap. The lower vent is more modest and a bit fiddlier to work as its slider’s within the cap, which is rarely ideal. 

With the RPHA 70 ST, these top vents are both admission AND exhaust vents. The switches on the top/side vents are likewise there to help manage not just the measure of cold air entering the protective cap yet the measure of warm air leaving it as well. Since the RPHA 70 ST is intended to work for the two games and visiting riders, they’ve put forth a unique attempt to make vents that work in a sports bike fold just a more upstanding position. With everything taken into account, it’s hard to blame the venting on the RPHA 70 ST. 

Sun Visor and Shield 

The reasonable safeguard that comes as standard has both HJCs fast fire II speedy delivery system and is Pinlock antifog-prepared. The quick-fire system functions admirably to whip off the visor with a little quarrel. Another thing that we’ve not run over before is a two-position safeguard lock. Close the safeguard as ordinary, and the safeguard secures position. That is not new, and loads of head protectors do that – and you need to push the safeguard up at the catch, and it opens in a single activity. Be that as it may, with the RPHA 70 ST, you can likewise slide the lock to one side, and it’ll bolt the safeguard shut – so even in a mishap where the catch is thumped, the safeguard shouldn’t open. 

HJC likewise figure they’ve overhauled the safeguard gasket to give a shockingly better fit, lessening water/dust entrance and fixing out more outside sound. This is conceivably an invite improvement as we do once in a while hear people groaning about helpless fixing on HJCs, so ideally, this will improve things. At last, on the fundamental safeguard, it has an ‘aired out’ position which numerous riders like; it’s great as a defogging position allowing in a touch of ventilation while still ensuring the face. 

HJC considers it a ‘wire type’ sun visor, meaning it’s more controllable – not just giving the choices of either completely up or completely down yet permitting you to drop it down however much you like. They’ve likewise planned it, so the switch is further advanced and simpler to reach and made the slider overall quite furrowed, so it’s not difficult to work in gloves. The sun visor is likewise against haze-covered. 

Looks and Graphics 

With its thick moldings and air impacted spoilers, the HJC RPHA 70 looks probably as current and deliberate as any cap available today. Quite a bit of that is tied in with making a protective cap that works; about lessening rocking and improving stability. What’s more, it’s also been molded to make a pressing factor differential to help draw air through the cap for ventilation. 

Yet, it’s not just about the air. That confounded shape’s also intended to make the head protector look outwardly minimal and fool the eye into believing it’s more modest than it is. And all that plan work is highlighted by some very striking designs. You have the typical decision of matt or gleam in there; there’s additionally the Octar, the Dipol, Grandal, and Lif illustrations – most accessible in, at any rate, a few distinctive shading combos. 

Weight and Feel 

Notwithstanding the inward visor, pin-lock, and numerous components for vent conclusion, the RPHA 70 ST comes in at just 1538 grams (3.39 lbs) in size enormous inspected here. Weight isn’t the lone factor in general solace. It “feels” little, and since size medium and enormous units share a similar shell size, the conservative feel isn’t unexpected. 

The shell appears to carve a perfect way through the air with practically no pulling or lifting at expressway speeds. Windscreen or not appears to function admirably in any case. Head checks are additionally dramatization-free, and the cap is truly stable at speed.

Final Verdict

The HJC RPHA 70 ST is a sophisticated, sophisticated helmet. Not the cheapest, it provides many features and technologies for the money. Still, it offers a complicated laminate shell, a sophisticated shield and sun viewing system, and EQRS and anti-fog shield (not Pinlock).

Also, it is lightweight, but a full carbon RPHA 70 ST is available if you choose to have even a lighter version. And the RPHA 70’s carbon ECE variant was a helmet suggested by the UK Ride Magazine when they covered top sports touring helmets in 2021. In short, the RPHA 70 ST is a major overall pick, with which owners are very happy.
