About Marushin Motorcycle Helmets


The Marushin story started 1958 in Tokyo as helmets manufacturing company, led by Watanabe Shin. His business vision was shaped by strict quality consciousness and steadfast innovation strength, both typical virtues of Japan's rising economy during its golden years. The brand name Marushin came out from Watanabe´s first name which, when translated, reads as "reliable and tenacious".

Since the beginning, Marushin has been one of the pioneers who developed the fibreglass technologies applied to the shells of High-End helmets production. At the end of the sixties the production plants were expanded to match the fast growing demand.

Very early the further step was a very strong connection and cooperation with racing teams, so, since the early seventies the results came out with several worldwide championships. Since 1980 Marushin got the benchmark as test-winner among the most qualified international competition.

HELMETS

Marushin NZ are distributors of two types of helmets so far; 999 and XMX. Each is made of unique materials developed by Marushin engineers & are the benchmark for current safety standards.

The 999 is made of X2F StoneFibre. X2F StoneFibre has an insignificant higher density than normal Fiberglass, but fundamentally better tensile and compressive strength characteristics. Because of this it is possible to receive thinner and lighter shells compared to normal Fiberglass. That saves weight. Although the name StoneFibre might assume that the shell is very hard, the opposite is the case. The MARUSHIN philosophy is, to build shells after the soft shell concept. This has a positive effect when crashing, because the shell can destroy more impact energy in the first nano seconds of the crash. The energy can be distributed across a wider area rather than just one single point. Of course here the shell works together with the specially designed and developed EPS core. 

The fabric of X2F StoneFibre is 100% organic and nontoxic. At the same time it is resistant to UV, corrosion and acids. X2F StoneFibre fibres are being impregnated with a weight optimized special resin after being woven into mats. Because of this preimpregnation the material is called a „prepreg“. The mats are laid onto a positive mould of the future helmet in a predefined order. That mould is made of flexible silicon. After the laying process has been finished, the mould is being brought into the negative mould of the helmet. An exactly calculated amount of pressure makes the ballon press the X2F StoneFibre layers onto the negative mould made of steel. The inner side of the negative mould has the future shape of the helmet as well. A stable and durable connection of mats and resin is being generated. The shell is born. In contrast to the classical way of Fiberglass production the SMC process (sheet moulding compound) ensures an optimum allocation of the resin. An absolutely precise shell without unnecessary resin buildups is the result. This way of producing is lightest possible way to build a Duroplast shell without losing sight of impact results.

The XMX is made from 3K Aviation Quality Carbon. Carbon is not equal to Carbon. MARUSHIN only uses special 3K woven Aviation Quality Carbon coming from aircraft construction. That material is extremly resilient and breaks shatterproof. That is an important point, because the shell of the helmet shall break when crashing to destroy impact energy. Because of the laying method of the 3K structure the fibers are woven and crossed in a way, that no part can break away to hurt the rider. The prejudice, that Carbon is very hard and not so flexible can easily be refuted by a simple example: The wings of an Airbus hang down while parked at the ground. In the air the air flow lifts them up. This characteristics make the 3K woven Carbon the perfect material for helmet building according to the soft shell concept, which MARUSHIN pursues.

The expensive Carbon material is being processed in the SMC (sheet moulding compound) technique. 3K fibers are impregnated with weight optimized special resin after being woven into 3K structure mats. Preimpregnated mats like those are called „prepreg“. The mats are laid onto a positive mould of the future helmet in a specified order, which has been predefined by the MARUSHIN engineers. The mould is made of flexible silicon. After the laying process has been finished, the mould is being brought into the negative mould of the helmet. An exactly calculated amount of pressure makes the ballon press the Carbon layers onto the negative mould made of steel. The inner side of the negative mould has got the future shape of the helmet. A stable and durable connection of 3K mats and resin is being generated. A light
weight shell is ready. In contrast to the classical way of Fiberglass production the SMC process ensures an optimum allocation of the resin. An absolutely precise shell without unnecessary resin buildups is the result. This way of producing is lightest possible way to build a Duroplast shell without losing sight of impact results. 



SAFETY

MARUSHIN exceeds official safety standards. Previously accepted standards are no longer state of the art and MARUSHIN has clearly moved the goalposts significantly. Science tells us: The more energy will be destroyed in the first nano second of the impact, the less serious the injury will be. Because of this, MARUSHIN engineers have developed the soft shell concept, which takes its inspiration from advanced research into crumple zones by the car industry. Ask yourself how a soccer player can head a ball into the goal, if the cross hits him with 450kp. If the ball was hard, the player would be killed instantly. It is only because the ball can absorb and distribute the energy across a wider area – the whole head, rather, than just one point – that the player does not get hurt.



Our philosophy of manufacturing safe and light helmets ensures success. Continuous tests of motorcycle helmets of all brands, bought at random from resellers by the Department of Transport, have led to a new safety ranking – SHARP. SHARP tests helmets according to additional criteria of other standards. These have been established in COST 327. The absorption of energy and lower velocity gains special importance. ECE R22-05 specifies a value of 7,5 m/s – SHARP also tests at 6,5 m/s and 8,5 m/s. This means a broader safety spectrum is covered. 999 was awarded an excellent four star rating in the SHARP safety scheme. All tested helmets therefore provide optimum safety and comfort for the rider. As a brand MARUSHIN supports SHARP tests and uses the feedback for the development of new helmets. You can see the success of that in our range.
