heavy, design sucks, used by messengers

yung mga GDR na binebenta dito sa atin ay mukang di sya Orig kaya ganyan. Di nyo ba napansin? iisa ang design? saka lahat eh modular.

pangit yang GDR.. dami pa peke kaya kahit na orig bilhin mo mukang peke..

parang "GOR" pa ung logo kung basahin sa malayo.. (GORILYA) :O

Nagtataka lang ako kung bakit ang pic na ito ay laging nagiging testament sa pagiging hindi maganda ng isang helmet. Di po ba na ang design ng helmet is to break upon impact? Sa pagkawasak nya upon impact is what helps sa pag-absorb ng shock. And di rin po natin alam kung ano talaga ang nangyari kung bakit nabasag ang helmet na to. Kasi kahit ano pa ang helmet mo, kahit arai man o shoei, pag nagkaroon ng malakas na impact, siguradong mababasag din sya. For me, mas maganda yung mabasag yung helmet upon impact kesa naman sa buo sya pero lahat nung shock nung impact ay maisalin sa bungo ko.

Nagkataon lang na GDR yung suot nung rider (RIP bro) nung nangyari to, pero kahit na anong helmet, mababasag din yan pag malakas ang impact.
As long as orig na GDR at certified sya then that would be good enough for me. The same as any other helmet na certified.

imho, di dapt mabasag ang helmet especially sa polycarbonate shell,yung shock wave nman dapat ma absorb ng styrofoam..yung bali sa leeg ang ewan...

kng nagkaroon ng Craniotomy yung bangkay from that motorcycle accident, then malalaman natin kng yung GDR helmet nya ay nakatulong sa pagreduce ng impact based sa findings ng Neurosurgeons.. ive seen a lot of GDRs, including FAKE ones.. ang material na ginamit ay hindi polycarbonate kundi hard plastic (brittle)..parang material na ginagamit dun sa fairings.. yung ibang display nga na GDRs, nakadisplay pa lang pero may mga cracks or basag na.. at isa pa, yung iba nga pwde mo mabasag or matwist using your bare hands..

pero may kasama ako naka-GDR din.. mga 2k bili nya.. pansin ko iba quality nya kasi nacompare namin sa isang kasama namin na GDR din at nabili nya ng 1.1K..

bottomline.. ok ang magtipid.. basta be practical.. itigil ang maling pagtitipid..invest on safety not on speed.. ride safe everyone!

ano nangyari sa rider??? nakaligtas ba?

patay bro..

Tingin ko ECE approved naman yan... Di naman nila ilalagay yun kung hinde totoo. Basta orig GDR, ayus na yun.... Kung yun lang talaga kinaya ng bulsa mo eh....

there are fake gdr helmets already going around. so please buy the original gdr from reputable dealers na lang....chris sports, blade, active moto carry the original gdr helmets.
How will you know fake gdr helmets? Try squeezing the helmet. If its soft and flimsy then for sure its fake.

ano nangyari sa rider??? nakaligtas ba?
DOS ang rider due to spine injury. buo ang ulo at mukha nya.

Marami na nga nagkalat na fake na helmets, kaya better to buy the original..

I agree to you sir, this only shows that the helmet done its purpose.
To absorb all the impact during the accident. Some of us here go for the brand and the price not for the purpose of the helmet. I don't care if it is the cheapest or the unknown brand on the market as long as it pass the standard i will go for it.
Buy the Original not the Fake ones

Ride Safe Everyone....

yan sir totoo.. yung binebenta sa atin hindi totoo.. may naka encounter na akong GDR na orig.. ibang iba itsura sa mga GDR na binebenta at meron din kasi akong gdr kaya kinumpara ko..

Ask ko lang po, kung hindi po ba GDR ang gamit nya, maliligtas po kaya siya? As in, di po ba siya matutuluyang mamatay nung pagkakataon na yun?

Nangyari po yata yan during ride sa Marilaque, nag overshoot sa twisties.

May he rest in peace.

kung hindi full face ang gamit nya, posibleng hindi sya Dead on the Spot. puedeng basag ang panga nya at mukha pero may chance pa na umabot pa sya ng hospital kahit na comatose sya.
I still think he would have died. iba nga lang ang injury. instead of spine injury, malamang mukha nya ang durog.

orig man o hindi ang helmet natin kung masyado tayong barubal sa kalsada hindi rin tayo maililigtas ng helmet or kahit ano man

DOS ang rider due to spine injury. buo ang ulo at mukha nya.


helmet will absorb some of the impact . the picture show that it absorb most of the impact kasi nabasag sya, orig man o hindi, mababasag yan, kung talagang malakas ang impact..

and i think base on the picture, tumama una ang ulo kung saan man, kasi hindi naman mababasag ang helmet kung hindi malakas ang impact.

try a sudden front brake of you're MC the momentum of you're bike can stop instantly or so, but the momentum of you're body will still continue forward, unless an opposite force will stop it... (hindi ko alam kung tama ang explanation ko).

helmet can save you're face but it will not protect you're neck and the spinal

A very simple but effective explanation of one of the laws of physics. I remembered na may nagsabi sa akin sa forum na may reflexes rin daw ang tao to protect his head in case of an impact kaya mas maganda daw pag walang helmet. This is a very appropriate answer. Kahit gaano kabilis reflexes mo, you can never cheat the laws of physics.

Mas maganda na may sasalong certified helmet sa impact ng crash kesa sa saluhin ng ulo mo.

So just go for the original ones. Kahit mura, basta certified. Wag na nating isugal buhay natin.

ano nangyari sa rider??? nakaligtas ba?

...yang nag semplang na yan mabilis ang andar nyan...sa marilque "sabi ng mga frends".hindi k alam kung peke or orig ang gamit nya ..kung mabilis ang andar mo siguro malakas ang impact talagang basag talaga....

Skull - protection for our brain
Helmet - protection for our skull

Sana may expert dito na makakapagexplain para maliwanagan tayo regarding sa helmet.

IMHO po cguro dahil china made etong GDR baka fake yun helmet na GDR na gamit nitong rider. kasi sa china lahat ng bagay kaya nilang gayahin. nag work ako dati sa factory ng plastic marami kasing klase ng plastic meron mal***** meron makunat nakalimutan ko na yun mga tawag dun eh sensya na. may plastic na madaling mabasag meron naman hindi meron din plastic na di madaling masunog like dun sa mga outlet ng electricity yun mga kulay brown na eagle ang tatak di basta basta nasusunog to. kaya mgayon di pa rin tumitigil ang mga researcher para sa mga matitibay na plastic na pwedeng gamiting sa helmet para ma-lessing yun impact upon collision. ano kaya difference ng 1-5thousand na helmet sa 20-30thousand price na helmet???

Sana may expert dito na makakapagexplain para maliwanagan tayo regarding sa helmet.

sir anong klaseng explanation ba ang kailangan para maliwanagan ang dapat maliwanagan...

we wear helmet to protect our head, to lessen the force of impact absorb by our head.

you may have the most expensive helmet in the world, but it doesn't mean that you're totally protected ....

diba yong mga sinaunang helmet na ginamit is yong tinatawag ngayon na tabo...

pero dahil nag eevolve ang mga motor pati helmet nageevolve din..

try nyo mag ride ng walang helmet at may helmet, pansinin nyo may pagkakaiba ang driving style nyo.

heavy, design sucks, used by messengers



bakit ano ba helmet mo? mayaman ka ciguro tandaan mo mas marami mahihirap kesa mayaman baka di mo alam may messenger na may masteral pa mahirap lang mag hanap ng trabaho dito sa pinas kaya ganyan ano ba natapos mo!!! baka B. S. vulcanizing ka lang hirap kasi dito dami mayabang di nila iniisip mga post nila dito. bago mag post isipin mo muna MORON!!!!

another trol!!!!!!!!!!!!!!!!!:I:I:I:I

heavy, design sucks, used by messengers

mga bossing baka gusto nitong taong ito na ang helmet nya ay magaan at may design kaya gamit nya yong, tabo or yong pang biseklita...

baka pag nakakita sya ng isang messenger na helmet eh branded, baka ihampas pa sa kanya..

@Topic.

kung yong pic ba ng basag na helmet, eh ARAI,SHOEI,ZEUS at iba pa.
Ano kaya sasabihin ng mga tao pag ganon.

Sasabihin siguro, fake yong Zeus helmet nya or Arai na helmet nya

di ako nanghihinayang sa mukha nya sayang yung caberg dual visor ko kung hahampas ko lang sa kanya siguro dun ko malalaman kung matigas talaga at ece at dot policarbonate yung helmet ko na yun matest kaya!!!:evil:

peace to all, brothers in bikes,,, anong kaguluhan ito...well, going back to the topic, as motorcycle enthusiasts, we have to consider, first and foremost our safety...that's why once we get to own a bike, we have to invest on protective gears,,hindi biro ang hobby natin,,this is quite dangerous,,lalo sa mga panahon ngayon,,,HELMET..yes..in fact, when i got my first mc in 2005, isinabay ko na rin ang helmet ko..that time, trip na trip ko yung Zeus 506, half-face..a year later, kumalat ako..salamat sa helmet..and those gears with me..nasira lang ang pants ko and nagasgas ang visor... word of advice: NEVER SETTLE for inferior helmets. mahirap magsabi ng brands, pero i know you guys know what im talking about.. basta never settle for anything less, USE your HEAD... WEAR a HELMET...teka sinabi ko ba na mahirap magsabi ng brands. pardon me,,but experience wise.. i think kung safety lang din ang habol mo. you should settle for HJC, ZEUS...if you have enough dough.. settle for ARAI, AGV, SHOEI, BELL, KBC..ang daming brands,,.RIDE SAFE!!! :clap::clap::clap:

regarding ur post..how about INDEX HELMETS?? :rolleyes: its my first helmet..un naka decorate nalang sa bahay kasi nasira na ung strap nya :D

kng nagkaroon ng Craniotomy yung bangkay from that motorcycle accident, then malalaman natin kng yung GDR helmet nya ay nakatulong sa pagreduce ng impact based sa findings ng Neurosurgeons.. ive seen a lot of GDRs, including FAKE ones.. ang material na ginamit ay hindi polycarbonate kundi hard plastic (brittle)..parang material na ginagamit dun sa fairings.. yung ibang display nga na GDRs, nakadisplay pa lang pero may mga cracks or basag na.. at isa pa, yung iba nga pwde mo mabasag or matwist using your bare hands..

pero may kasama ako naka-GDR din.. mga 2k bili nya.. pansin ko iba quality nya kasi nacompare namin sa isang kasama namin na GDR din at nabili nya ng 1.1K..

bottomline.. ok ang magtipid.. basta be practical.. itigil ang maling pagtitipid..invest on safety not on speed.. ride safe everyone!

right on bro, di natin alam kung pano sya mabangga. when i receive my agv visor it was marked with gdr on the tag, meaning ang gdr ay sub contractor ng agv and it might be a big possibility kasi ang s4, stealth at titech ay made in china. so, kung orig na gdr ang nakuha mo it would help you out alot in case na maaksidente ka pero kung peke.... oh well, parang russian roulette yan.

with all due respect i don't think helmets are designed to break on impact kasi pano na lang kung on impact nag break na yun helmet po then yung momentum mo will push you pa what if kumaskas yung face mo sa pavement? did the helmet served its purpose?...example nyan yung kay sete gibernau sa Catalunya Grand Prix 2006 ata yun (you can watch it sa youtube) after nun impact gumulong pa sya the helmet is still intact ang nasira lang yung visor...hmmm ano kayang helmet gamit nya nun?

sir base on the picture, talagang malakas yong impact kaya sya nabasag, meaning that it absorb the impact until it reach it's limit kaya nabasag. kaya nga nabasag kasi talagang grabe yong impact nya. and outer shell lang naman ata yong nabasag at hindi yong inner shell so intact pa rin yong inner shell nya.

depende naman sir kung pano yong pagkakaaksidente , kahit pagulong gulong ka dyan, at nag slide kung hindi direct sa helmet yong impact, magagasgasan at masisira lang yong visor..

hindi ko napanood yong video..

try mo magsuot ng bracelet na maluwag tapos sumuntok ka, imagine mo yong kamao mo yong ulo mo at yong bracelet yong katawan mo. tignan mo kung ano effect.. yong kamao mo, nakastop na pero yong bracelet eh sumunod at nagstop na nong nasa kamao mo na.

so yong theory na spinal injury is malaking tyansa na yon an kinamatay nong rider

"Motorcycle helmets are generally designed to break in a crash (thus expending the energy otherwise destined for the wearer's skull), so they provide little or no protection after their first impact."

How do helmets work?
Helmets are normally comprised of four elements; a rigid outer shell, a crushable liner, chin straps or a retaining system and fit or comfort padding. The rigid outer shell when present adds a load-spreading capability, and prevents objects from penetrating the helmet. It's kind of like an additional skull. The liner, usually made of EPS (expanded polystyrene) or similar types of materials absorbs the energy of an impact by crushing. The chin strap when properly buckled and adjusted along with the fit padding helps the helmet remain in position during a crash.
Helmets work kind of like a brake or shock absorber. During a fall or crash a head is traveling at a certain speed. Since the head has weight, and is moving there is a certain amount of energy associated with the moving head. When the helmet along with the accompanying head impact an unyielding object; a rock, a wall, a curb or the ground the hard shell starts by taking the energy generated by the falling helmet (head) and spreads it over a larger portion of the helmet, specifically the internal foam liner. The foam liner then starts to crush and break which uses up a lot of the energy, keeping it from reaching the head inside. Depending on how fast the head is traveling, and how big, heavy and immovable the object is the faster the head slows down, and the more energy is present. In short everything slows down really quickly. A helmet will effectively reduce the speed of the head by breaking and crushing which reduces the amount of energy transferred to the brain. The whole process take only milliseconds to turn a potentially lethal blow into a survivable one.

kahit anong helmet pa yan mga bro parepareho lang yan. very simple...kung gusto ng rider ng sobrang bilis ng takbo nya dapat sa circiut sya pro kung ride or adventure habol ng isang rider eh diba pwede nman tayo magpaandar ng normal speed and distance sa ibang sasakyan. all we need is DICIPLINE on the road.:banana:

I think mga GDR for sale dito sa atin japek..choice ito ng ibang rider na bilhin ciguro swak lang ito sa budget nila...hopefully makabili na tayo lahat ng best helmet...

safe riding na lang mga bro...wag na mamintas kung pangit mga helmet na suot ng iba intindihin na lang natin di pa nila kaya bumili ng best helmet..ciguro me plan naman din cila...:)

kakatakot.. pareho ng helmet ko ung basag sa pic.. wala pa kasing budget eh.. student fair palang.. hehehe.. pero plan ko bumili ng HJC ipon pa ko, defensive driving lang lagi para iwas accidente..

kakatawa ung bayaw ko bumili ng ZEUS na 508W tapos laging gamit eh yung tabo na helmet.. sayang daw baka magasgasan.. hehehe..:clap:

fake na helmet nag kalat sa quiapo, any brand meron, may shoei pa nga e, tinanong ko how much sabi 800 daw may bawas pa. heheeh.. baka pag nabagsak un biyak kaagad. we should buy original helmet and gears, para sa atin din naman yun e. sabi nga ni master desk_mullen " may pambili ka ng magandang motor.... ni matinong helmet wla? (common reason: budget) lalabas yan pag nasa hospital na.mas masarap ba magbayad ng hospital bills kaysa mag gears?... "

right on bro, di natin alam kung pano sya mabangga. when i receive my agv visor it was marked with gdr on the tag, meaning ang gdr ay sub contractor ng agv and it might be a big possibility kasi ang s4, stealth at titech ay made in china. so, kung orig na gdr ang nakuha mo it would help you out alot in case na maaksidente ka pero kung peke.... oh well, parang russian roulette yan.

Just to clarify a bit.... AGV titech helmets are made in Europe. AGV s4 helmets are made in China....GDR is not a sub-contractor for AGV

Sa panahon ngayon dali na lang pekein lahat ng bagay. kaya ingat sa pag bili maging mapanuri sa lahat ng bibilhin bagay....ako rin balak ko buli ng mas ok na helmet.

how to select a helmet and wear it correctly?

‧ Determine your fit – Measure with a tape horizontally around your head at a height of 2.5cm above your eyebrows. Then choose the helmet size closest to your head.

‧ Try the helmet – Widen the helmet opening by pulling both chin strap and wear the helmet. If the helmet is not tight, it is too big for you. Choose a smaller size and you should feel tight.

‧ Check fitting – Make sure the inner lining fits securely around your head by pressing both your hands each side of the helmet and turn left and right. See if it can be move easily. If yes, choose the smaller size.

‧ Check retention system – Fasten the chin strap as tight as possible. Then put your hand at the chin area and pull upwards. If the helmet shows any indication to come off, do not use the helmet.

Should i change my Helmet after an accident?

You must destroy your Helmet involved in accident and get a new one. The helmet protected you from an accident may still looks good, but the strength and absorbsion ability is weaken. Small crack on the shell may not be visible with naked eyes.

What is a life spent of a helmet??

The SNELL Memorial Foundation recommends a helmet life spend is 5 years. Therefore a helmet may not show any malfunction or damage for 5 years, we recommends discontinue using the helmet.

Which is the standard?

There is no black and white in which standards offer better protection for the rider. All standards are meant for the safety of a rider as long he/she ride within the speed limit.

sabi ni ZEUS.

Nagtataka lang ako kung bakit ang pic na ito ay laging nagiging testament sa pagiging hindi maganda ng isang helmet. Di po ba na ang design ng helmet is to break upon impact? Sa pagkawasak nya upon impact is what helps sa pag-absorb ng shock. And di rin po natin alam kung ano talaga ang nangyari kung bakit nabasag ang helmet na to.

As long as orig na GDR at certified sya then that would be good enough for me. The same as any other helmet na certified.


Sir yung mga arai at iba pang well known helmets ay subok na... di ko naman sinisiraan yung ibang helmet pero yung napanood ko sa dicovery ch. binabagsakan ng matulis na bakal yung arai pero di man lng nag crack...

ride safe to all..always wear your. helmet

ride safe to all..always wear your. helmet

Yes sir, di nga po siguro mabubutas yung arai pag binagsakan ng matulis na bakal pero I'm sure that the inner lining will be crushed because of the impact. Yung pagbasag nung inner lining is what absorbs the shock of the impact. Para po hindi maitransfer yung shcok sa ulo. That's what a helmet is supposed to do. Kung bibigyan nyo po ako ng helmet na di masisira pag hinampas ng malakas, di ko po ito tatanggapin kasi lahat ng shock ay maililipat din lang sa ulo ko. Buo nga yung ulo ko, pero my brain would certainly turn into mush. Di lang po protection from objects that might enter our head in case of a collision ang binibigay ng helmet, kundi protection from the shock that the impact produces.

Just like the design ng mga kotse ngayon, may mga impact crush zones ang mga bagong kotse sa harap at likod. this is to absorb the impact in case of collisions. Tumitiklop yung mga structural members sa harap at likod ng kotse to save the passenger cabin. kung sakaling matigas ang buong structure nung car then all the impact upon collision would be transferred to the passenger cabin which we don't want to happen coz obviously, dun tayo nakaupo.

just my two cents...

As you have said sir, ride safe to all!
