Arai enter the 2012 season with the RX-7 GP Corsair as their flagship
product. This is the helmet you will see worn by Dani Pedrosa, Leon
Haslam, Jonathan Rea and zillions of other racers. Except for their
individual colour schemes the helmets are standard production items.
Arai doesn’t do “works” helmets for special riders. (The top-tier Arai RX-7 GP is marketed in American as the Arai Corsair-V)
The RX7 is virtually unchanged for 2012 except for a modification to the
internal padding of the helmet. Arai calls this the FCS (Facial Contour
System) and it takes the form of a removable 5mm foam layer on the
cheek pads. The tiny adjustment is an indication of how much Arai is
encouraging riders to fine tune the RX-7 to their personal taste.
This is more important than it seems because one of the great strengths
of the RX7 is that it can be worn very tightly - and the tighter a
helmet is, the safer it will be. The downside is that Arai has a very
clear vision of what it sees as the shape of a human head. This is fine
if your skull meets Arai’s specification - but a real problem if you
don’t.
Arais come in a vast range of outer shell, and inner liner, sizes.
Despite the range of options if you don’t have an “Arai head”, it will
be impossible to ever get totally comfortable in one. It is also
critical to take the time and trouble to get the fit absolutely right -
perhaps more so than on most other helmets - because there is so much
adjustment available.
Your patience will be rewarded because once a rider has an Arai “set-up”
for him or her, it is like wearing a second skin. Quite literally, the
helmet will disappear from your consciousness and allow 100% focus on
riding.
In terms of safety, Arai claims to have raised the bar with the RX-7 GP.
Let’s start with the shell. Arai calls this a structural net complex
claiming that their “superfibre” is 40% stronger than conventional glass
fibres.
Certainly, with its aerospace “superfibres”, and resins, the RX-7 is a
world away from the fiberglass shells of old but it still enjoys the
benefits of resin and fiberglass construction. Primarily, these are that
the shell is designed to be sacrificial in an accident. In practice
this means that the shell self destructs during impact and in so doing
reduces the impact on the inner shell.
What makes the RX-7 clever is that the shell varies in thickness in
different parts of the helmet. This means that areas not likely to
impact the road - for example adjacent to the wearer’s ear - are thin
whilst the front and rear of the shell are much thicker. The area
directly adjacent to the visor aperture is particularly strengthened to
prevent flexing in the case of a face down impact: something I know
about all too well from personal experience!
The lighter the helmet, the safer it will be since a large heavy object
waving around on the end of a human neck, in addition to the rider’s
head, is highly undesirable. In terms of accident safety, and rider
fatigue, light is good.
There are many other good, safe shells being made by premium brand manufacturers today but an RX-7 is as good as it gets.
Ironically, the real life saver in a helmet is the inner polystyrene
liner rather than the outer shell. The liner absorbs the initial impact
and in so doing reduces the risk of the brain accelerating into the
skull. This might sound a little gruesome but it is what happens in an
accident. That’s why only very seriously dumb people ride without a
helmet - or wear bits of plastic kitchenware molded to look like Second
World War military gear.
The RX-7 has a triple density inner shell, again designed to give
maximum protection in critical areas. Arai claim that having an
extremely hard, and tough, outer shell allows a very soft inner lining
to be fitted. Reducing acceleration and deceleration of the brain is the
name of the game.
The RX-7 meets the ECE 22-05 standards, which doesn’t say much, and also the new Snell M2010 which does.
Peripheral vision is truly excellent with the RX-7 and the visor
aperture is sufficiently large so that there is never a feeling of
needing more.
Removing the RX7’s visor is still a bone of contention. Watch Arai
technicians at a race meeting and they can replace a visor in seconds. I
can change a visor, but with more effort, and Arai beginners take
forever. A lot of the problem is that with a helmet which costs the same
as a cheap bike the changee is terrified of scratching/damaging his
precious purchase and this nervousness doesn’t help matters. Arai says
the system is fine: a lot of riders don’t agree so it needs improving.
The RX-7 has an adjustable rear spoiler and when I first got the new
helmet I was like a “Top Gun” trainee adjusting the trim on my
supersonic jet. Then the novelty wore off. Again, in practical terms the
RX-7 is completely stable even in the dirty air which comes off a
classic race bike at high speed.
On the track or the road the RX-7 is both supremely comfortable and
utterly competent. Most helmets on sale are safe in most accidents but
when I was sliding down the track after hitting a patch of oil at
Donington I was very, very glad that there was a lot of Arai technology
between me and the tarmac. It is the very dangerous areas, skirting
death or serious injury, where a premium helmet pays for itself.
The finish and paintwork of the RX-7 is of show winning standard. I have
a, new for 2012, Randy II color scheme and this is a beautiful mix of
modern and classic – as tasteful as a top of the range Lexus but still
lively. When the helmet arrived, I just parked it at the end of my desk
for the day enjoying a true piece of moto-art.
In the final analysis, there is one question you should ask of any
journalist. Given the choice of buying the helmet you are testing or
having a free one from someone else, what would you do? For me, I would
always get my wallet out and lay my $920 on the shop counter to have an
Arai.
