RIDER ANALYSIS
I've wanted to try this helmet for
what feels like an age. I missed the
international launch back in 2022 (I
was racing at the Isle of Man TT, so
I feel that's a good enough excuse),
and getting one finally delivered felt a

bit like an early Christmas this year.
The S-R10 is by far the most
modern-looking helmet on the
market. Those massive side spoil-
ers, the elongated rear, reminiscent
of a cycling time trial helmet, which
is more than a bit of a coincidence
given reducing drag is everything in
cycling.
First, what I don't like. It is a bit
tighter to get on and off than I'd
have liked. The carbon construction
is super stiff, but once it's on, find-
ing a comfortable point at which to
wear it is pretty easy.
And, well, that's it for what I
don't like.
There are three main things I
like about the S-R10. The first is its
stability, especially at high speeds.
The S-R10 is rock solid when you're
tucked behind the bubble, as the
air just whizzes over the top and
doesn't have anywhere to create
pressure points on your neck. Down
Portimao's full-send front straight
on the fully naked KTM 1390 Super
Duke R, the S-R10 was gorgeously
stable, which has the obvious ad-
vantage of reducing the fatigue on
the top half of your body.
The second part I enjoyed was
the huge field of vision you get from
the eye port. 220° of side-to-side
vision is remarkable, and I could see
areas of the inside of a corner when
fully leaned over I hadn't notice
before.
The third part that was immedi-
ately noticeable and welcome is the
ventilation. Open all the vents, and
the S-R10 flows so much air that
you'd think the visor was cracked
open. It's especially noticeable on
the chin next to the visor lock, as air
gets ram-fed into the helmet, putting
those side extractors to the test.
On the top of the S-R10, airflow is
again top-notch, removing the heat
build-up and just making the fit that
much more comfortable.
I have not crashed in the S-R10 (I
don't intend to), so I will leave any
comments about impact absorp-
tion and rotational injuries to my
subconscious. However, it's nice
to see the number of times Jorge
Martin and Jack Miller have thrown
themselves down the road. They
haven't received any injuries above
the neck, so Alpinestars must be
onto something.
This is a seriously good helmet.

of the helmet. These ports are
integrated into the helmet's
shell, air coming through a
series of air ducts within the
inner EPS liner.
Alpinestars claims the
Supertech R10 weighs
1540g/3.4 pounds but ours
topped the scales a touch
heavier at 1571g/3.74 pounds.
Not a massive difference but
still worth noting.
Those huge side
heat extractors on
the jawline really
do work.
