HJC C70: Lower price polycarbonate all-rounder full face helmet.


HJC C70 full face polycarbonate motorcycle helmet.

The HJC C70 is HJCs replacement for their IS17 helmet. Which means it’s designed to be a great all-rounder motorcycle helmet at an affordable price.

It also means it has one heck of a job to do – to replace one of their best selling, highest safety rated and fullest-featured crash helmets on the market.

Like the IS17, the C70 is a polycarbonate shelled helmet with a drop down sun visor, micrometric fastener, quick release and Pinlock-ready main visor. But sadly, unlike the outgoing helmet, there isn’t a Pinlock in the box.

So if you’re after a good quality, well performing but affordable helmet that’ll work from any bike from moped to a tourer (but not so well on a sportsbike) then read on as we tell you all you need to know about the HJC C70 helmet.

  • Full face all-rounder helmet
  • Polycarbonate shell
  • Drop down sun visor
  • Made in 2 shell sizes
  • ECE and DOT versions available
  • Pinlock ready visor (insert not included)
  • Micrometric fastener
  • Quick release main visor
  • Sizes XS-XXL
  • Expect to pay £130-£150

 (more about helmet safety)

HJC has a pretty good reputation for safety, not least among their polycarbonate helmets.

After a hi viz C70? This one’s the HJC C70 Lianto

The helmet it’s replacing was actually given a maximum safety rating of 5 stars by SHARP, and of course the HJC C70, like all helmets for sale in Europe, is also ECE tested & certified.

In the US it’s been certified DOT compliant too, but over and above these mandatory tests, none of the independent helmet safety testing labs have published any results for the C70 yet. When they do, we’ll publish all the details here.

If we look at SHARP test data over the last few years, their last two tested polycarbonate helmets scored 4/5 stars for safety. That’s the full face CS-15 and the IS Max II modular helmet.

And in 2019, HJC crept in to our top 10 safest helmet brands list at number 9 spot.

OK, so these aren’t giving you info specifically on the C70’s safety, but because the C70 shares so much with the outgoing (and 5 star rated) IS-17, hopefully it means safety’s gonna be similarly great for the latest range of polycarbonate HJC helmets.

Right onto other safety stuff…

The visor’s been designed to be wide to give good peripheral vision. And an integral drop down sun visor’s always really useful to have on your helmet, to stop you getting caught out when the sun’s blinding; so that’s a very worthwhile safety addition.

And finally, the HJC C70 is made in two shell sizes. That’s probably to be expected for a helmet at this price point but we like to see more these days as more shells means a more optimised fit, less weight and – arguably – improved safety.


(more about helmet ventilation)

As you can see from the photos, there’s one large top vent and a single vent in the chin bar too.

That chin bar vent is covered by a sliding panel used to close it off or open it up and direct air behind the visor.

The top vent is opened by a small slider right on the top of the helmet. It’s actually really easy to find and, because it sticks up nicely, it’s simple to use and means gloved fingers can easily grip it .

This top vent passes air through the helmet shell and into grooved channels inside the helmet.

Given it’s a similar system to the outgoing helmet, we’d expect ventilation inside the helmet to be adequate but not amazing.

Same goes for that chin vent. And if you’re riding in Europe, you’re going to want to buy and fit a Pinlock antifog insert in there to stop fogging.

If you’re a summer-only rider, you might get away without. Otherwise, expect the visor to fog up on cold mornings or when it rains.

Pinlocks are about £30.

(more about visors)

OK, the visor on the C70 does pretty much everything you’re going to need on your helmet – except come with a Pinlock antifog insert.

It is Pinlock-ready, meaning it’s got those Pinlock pegs fixed on the visor so you can buy a Pinlock and fit it on there. Just some helmets come with the Pinlock itself in the box – whereas the C70 doesn’t.

You can understand why the C70 doesn’t come with an insert. HJC obviously wanted to keep the cost of the helmet down and including a Pinlock would’ve nudged it up a bit. But it’s a real shame because us Brit riders need all the anti-fog help we can get!

Other than that, the visor system on the C70 looks pretty good.

It’s nice and wide to give good peripheral vision. It also features HJCs RapidFire II visor quick removal system. That’s one of the best and just involves raising the visor, squeezing a trigger and popping off the visor.

Why do you need that? Well for easy cleaning mostly. Get home covered in dust/bluebottles/wasp juice – pop it off and wash it in soapy water. Job done.

The C70’s visor’s also got a small locking mechanism on it. When you snap the visor closed, it’ll click-locked. But it’s easy to push up on the visor tab, releasing the lock and opening the visor in one go.

A visor lock’s probably not that important to most of us outside a race track, but it does help a little with securing the visor against the visor gasket and keeping wind/rain out.

Sun Visor

(more about sun visors)

A sun visor’s always a mega useful addition to a helmet. Not only is it really convenient – quickly dropping it down to keep the sun out of your eyes – but it’s also an important safety feature when the sun’s low and dazzling.

The sun visor on the C70 is operated by a slider sat high up and far back on the crown of the helmet. It’s kind of an OK position for the slider, though it can be a bit tricky to find until you get used to it.

Unlike the old model which returned the sun visor to it’s fully up position using a spring-loaded, button operated mechanism, the C70’s sun visor needs to be slid down, then manually slid back up again.

That does give you the option of choosing exactly which position you drop it down to – whether you want it fully down or just down a little.

Plus, the spring mechanism on the old IS17 was known for getting a bit tired – meaning it’d raise it a bit but not fully. So this system does away with that potential problem.

And if you prefer riding in sun (or normal) glasses, then the C70 should be good for glasses wearers because there’s glasses grooves inside the C70, so they should slot into the helmet without pressing into your head.

Comfort and Sizing

(more about comfort and sizing)

The inner lining on the HJC C70 is removable and washable and uses a material HJC calls SuperCool. That’s a moisture wicking and antimicrobial material that’s soft to the touch too.

Black/white/red version of the Lianto

It’s available in sizes XS-XXL. If you are looking to buy a C70, check out our helmet fitting guide first. Then when you receive the helmet, make sure it’s a reasonably tight fit (but expect it to give a little over the first days/weeks) and make sure it’s comfortable.

Ensuring your helmet fits correctly should be your number one priority when buying a helmet because a correctly fitting helmet means the helmet can do its job in an accident. If it’s too loose, it won’t give you the best protection.

And make sure you always tighten your chin strap fully, because loose helmets are known to come off in accidents if they’re not correctly tightened.

Looks & Graphics

HJC’s expecting to sell lots of C70s and you can see that in the number of graphics available.

If you’re after a solid/plain helmet, there’s a gloss black and gloss white as well as a matt black version (called semi-flat by HJC).

This one’s the Troky in black and hi-viz

And there’s also a heap of funky graphics that we’ve scattered up and down the page: the Valon, Lianto, Troky and Boltas available in allsorts of colour options including some hi-viz.

Other stuff – fasteners, glasses, aero, warranty

The C70 is available with a double-d ring fastener from most retailers in the UK, or micrometric fastener if you’re in Europe or the US. Either system’s fine – click the links to find out more about either fastener if you’re not sure.

Black and orange C70 Troky

There’s glasses grooves inside the comfort liner which are a slot to let the stems of your glasses sit comfortably inside and not press against your head. So you should be OK with the C70 if you wear glasses.

HJC says the slightly redesigned shell of the C70 was wind-tunnel tested to reduce noise, buffeting and give all round improved aero performance.

It comes with a removable breath guard inside the box to help reduce fogging on the visor.

Finally, whereas some HJCs come with a 5 year warranty (RPHA range of helmets) the C70 only comes with a paltry 1 year guarantee 🙁


The outgoing IS17 was a great helmet, so we’ve got high hopes for its replacement, the HJC C70.

The C70 has a slightly redesigned shell for improved aero, but other than that and a few other minor tweaks, it’s a very similar helmet. Which means it’ll (hopefully) be mega safe like the last helmet and that visor system and overall comfort level should tick all the right boxes.

It should also mean that if you’re after a budget helmet for your more upright motorcycle (so nakeds, adventure bikes etc. but not sportsbikes) that offers real performance and all the major features you need – like sun visor and Pinlock-ready main visor – then we’d expect the C70 to deliver.

Good Alternatives to the HJC C70

HJC make some great performing lower-priced helmets, and we expect the C70 to be a good buy. But there are quite a few other great helmets available for not very much money.

Here’s a selection of recommended alternatives to take a look at. These have all scored well on safety tests – and you can find more by using our smart(ish) filters page, for example by checking the ‘budget’ and ‘safest’ boxes to find lower priced helmets that offer great safety levels.

If you’d consider a modular helmet, HJC’s FG-ST is a SHARP 5 star safety rated fibreglass lid that doesn’t cost the earth. It’s got a sun visor and comes with a Pinlock in the box.

Back to full face helmets – the Shark Skwal 2 is SHARP 4 star rated, has a Pinlock, sun visor, is reasonably light weight and has in-built LEDs for extra visibility.

Another maximum safety rating helmet is the full face composite fibre X-Lite X-702 GT. It’s light weight and has great ventilation too.
