How many of you change helmets after 5 years from the manufacturing date? My GXT has unknown date, so let's not count that. Neither does my Index. :troll: Feels sayang to throw away a 5 years old but good looking Shoei X12, right?

can you find a real serious warning frm any reputable helmet maker that says that helmet should be changed after 5years.
i mean a real serious warning/disclaimer.

what if rider only wear 2 times a month, compare to rider wears everyday.

their helmet starts deteriorating once placed on the head?
or out frm factory?
what about helmet tht was on display for over a year... ??

all these have not been really studied...?

Seems you've not tried looking.
I think some of these sounds serious enough to absolve the manufacturers of any claims.

Shoei: Helmet Replacement
Ultimately, the useful service life of a safety helmet is dependent on the intensity and frequency of its use. Helmet replacement is recommended even if only one of the under-mentioned points applies:
1. The helmet was subjected to an impact.
2. The comfort padding or the retention system has become loose due to heavy use or display signs of deterioration. Test: with the retention system fastened, the helmet turns to the side when you gently shake your head.
3. The EPS liner has come away from the helmet shell.
4. The EPS liner shows signs of wear and is beginning to break up, or if it has been exposed to heat or a solvent and has melted. There are indentations in the EPS liner and/or white scratches can be seen on surfaces with black paint.
5. Even if none of these is applied, we, SHOEI, recommend replacement in 5 years after it's first purchased at retail.

Arai: How do I know when my helmet is past its best?
Arai helmets are handmade to the highest possible standard, and although after many years the outside shell can look as good as new, it’s the EPS polystyrene liner that loses its ability to absorb impact over time.
Arai recommend replacing your helmet 7 years after date of manufacture and 5 years after date of purchase to maintain the maximum levels of protection.
The EPS liner is effectively the shock absorber of your helmet, absorbing the force of an impact onto the shell. This is done by the cells in the poly styrene being expanded (EPS = Expanded Polystyrene) and filled with air to absorb impacts. Over time, even when not in use, these liners lose their air pockets incrementally, after 7 years, dropping the shock absorbing ability of the liner below Arai’s safety standards. This is why we declare the helmet due for replacement so it can properly protect you against impacts.

Caberg:
Is the production date visible on the helmet?
Researches have shown no evidence of degradation of the materials (used in the helmets manufacture) due to the mere effect of the times passing by. Nevertheless the exposure to the atmosphere agents (extreme hot and extreme cold), and the contacts with the vapors of the lubricants and gasoline normally used in the motor bikers environment may influence the molecular links of the materials used. Moreover, because of its own nature, the helmet often undergo to shocks of different amplitude that could limit its performances. For all these reasons and for the abuse to the comfort padding and for the technical evolution that make more modern and protective lids available, it is suggested to replace the helmet after 5 years of use. In case of intensive use this delay should be shortened accordingly. If a helmet supports a severe blow, even if there is no evidence of damage, it should be replaced.

basiliskyeah, i thought the same, as they wanna sell more helmets, until I looked it up.

Some say materials deteriorate, some say they don't. The question is, a 5 years old helmet new in box, how to calculate for non-Arai helmets. Means will use 5 more years, until 10 years from mfg date then replace liao. EPS are, polystyrene, the thing that supposed not to degrade over many2 years, right? Among other things like glue, duct tape, electrical tape or whatever things they may use.

TanJy1814 I think it means if there's any scratches or abrasion that removed the paint on the outershell of the helmet. I have a black Index helmet, very old, and it has not faded, just lost its gloss. Where is your helmet kept mostly? Got petrol fume or something like that that could cause color fade? How old is your GiVi?

Here's a read I came across: some facts, arguments, and how to sensibly up-cycle our helmets.

not outer shell... the inner EPS liner. EPS itself is white. but they put a black paint over it as a "marker" to be able to identify damages to the liner. example, if the helmet gets an impact powerful enough to dent the EPS, you will see the dent via the white scratches/cracks in the paint.
*
Yes, now that makes more sense. Thanks.

https://helmets.org/up1505a.htm
Found the link above saying old bicycle helmets were tested and the EPS conformed to original qualifications.

For motorcycle helmets, I think it boils down to luck, again. And the odds stack against us as a helmet ages, just like anything.

All in all, I'll keep using my old helmets lah, but inspect it more frequently. Recently I've been using fabric shampoo/foam to clean my helmet liners. Hope that doesn't degrade the helmet lah.

ur liner removable? if u wanna make sure they are fine and concerned...use johnsons baby shampoo.. baby shampoo is somewhat recommended especially if ur liners are not removable.

for me... all my liners are removable.. and i just shove them in a laundry bag and into the coin laundry washing machine and dryer along with the rest of my laundry... use normal laundry detergent mixed with some dettol and no softener.

been doing it for years... they come out real nice n fluffy n feel really nice once installed back to the helmet
*
Before this use Index, not removable. Would weigh down and sink the whole thing in a pail overnight with Dettol bleach dynamo concoction and dry it.

Had an LS2 FF, sold it before I need to clean it. That time it's only 200 a piece for top of the line.

Just recently got the GXT open face with removable liners and still new.

Now surveying and noticed some used Shoei for 5~800, year made 2009~2013.
Or considering a new i70 or IS Max2 for 800+.

GXT modular looks like an open face helmet with a make shift chin bar. I saved some money and went for the open face. The visor on GXT open face is better than most, and copies the Shoei Jet one IINM.

It's snug on the cheek and forehead and tight on the jaw.
Noisy, but improves with the face shield closed.
Still a lot of wind noise I guess from the low quality liner used.
Tinted visor is good optical quality.
Paid 60 for it, no complain la.

For a next level, I'd definitely say a decent full face. Other than weight, safety rating etc, additional considerations for me, would include availability of Iridium visors, and affordability of fresh liners. Like previously mentioned, these parts can cost a helmet.

I think the chin bar of the One2 is removable?

3~4x price difference. The liner material different sky and earth.

A good helmet really reduces the possibility of fatigue.
Good I don't mean super expensive, otherwise bangsa-wan becomes bang-sawan.

Any of you using carbon fibre helmet?
Last time I thought KYT selling the fluocarbon is genuine CF, found out later is painted.

had 2 michel open face for over 20years.
made by solidgold helmets which produce ltd index sgv apollo etc.
ltd index sgv too tight for my head, only michel feels comfy.
tht was in the mid 90s.

early 2k bought a SOL SO1, frm nks, tht time sol is marketed everywhere, brought in by winmaster (shark dist)
then they stopped dist SOL.

SOL quality, finishing, + features is good at tht time for the price. but d shape is still too oval..

michel retired i start to search for under rm100 helmet with removable inner with sirim sticker.
finally found one by KHI, helmet also have drop down visor. rm120 or less.

i like retro open face helmets, out of curiosity i wana find one tht has inner drop down visor, with 3tabs and also air vents.
no branded helmet produce tht, manage to find one made by SOL,discontinued model, but taobao seller still has it, ship over here, lucky din stop by kastam.. biggrin.gif

Thanks for sharing. Seasoned rider you are.

Michel I know, and I remember pretty much the same about SGV brands that you mentioned. Had a hand down fullface too, very tight, so I sold it. Seems they still make SO-1. I think that time SOL and ZEUS helmets are the upper class open face helmets. Oval shape means it extends forward for better jaw coverage, right?

I had an Index, then got a Fibreglass JAX open face, a rare find, but was stolen off my bike on a day I had to park outside compound rushing to a class. Index dropped, crashed, changed liner for more times that it deserved, and finally started to crack open at the cheek. Found the GXT earlier this month, and this topic opened.

Belum berani buy Shoei yet. Recently notice got Shoei X13 Carbon Snake selling for RM900... mana tahu I think is MT Helmet clone.
Thinking get a used GT-Air try try premium helmet.

How can I be sure that my helmet fits properly?
1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch (2.5cm) above your eyebrows. When done properly, you will have measured the largest part of your head.

2. Check your measurement with the helmet sizing chart (can be found under the helmets section, after selecting the model you are interested in), and select the closest size. As the helmet may not always exactly meet your head size, and your head measurement may fall between two sizes, first try on the smaller size.

3. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. Pull the chinstraps only, not the chinstrap covers, as pulling on the covers may rip them. If the helmet is not tight, it is too big for you. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug.

4. Now that the helmet is on:
• Check that the helmet inner lining fits snugly all around your head.
• Check that the top pad presses on the top of your head.
• Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
• Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
• Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
