Owner’s Manual
Öhlins Racing AB - The Story
It was the 1970’s, a young man named Kenth
Öhlin spent most of his spare time pursuing his
favourite sport: motocross.
Being a careful observer, Kenth’s attention
was continously drawn to one specic detail -
motocross bikes had more engine power than
their suspension could handle. It was not long
before Kenth realised that better performance
could be achieved by improved wheel
suspension.
Öhlins Racing was established in 1976, and
just two years later the company won its rst
World Championship title. Despite being in the
business for almost 40 years, the search for
perfection and new functions is still the main
focus of the company.

Congratulations on choosing the Öhlins TTX
shock absorber - the most unique and powerful
racing shock absorber available today. The TTX
shock absorber design is the culmination of ve
decades of Öhlins successful participation in
World Championship events.
This shock absorber draws on all the expertise
developed by Öhlins while winning more than
350 World championship titles.
The Öhlins TTX features a patented concept
with a unique concentric twin tube design, that
allows for the gas pressure to always back-
up the low pressure side of the main piston.
This design creates positive pressure build up
on both compression and rebound stroke. As
a result the TTX has a more direct damping
response, less risk for cavitation and works
with lower gas pressure. With the new Flowtechnology we redesigned the ‘check-valve’
system to balance wide valve openings and
quick open/close actions to handle a large
volume of oil ow. This gives the car improved
traction, comfort and predictability which
enhance the stability of the car.
Compared to a regular piggy back single tube
shock absorber, that has positive pressure
build up only on rebound stroke and relies on
compression valve resistance together with gas
pressure to avoid cavitation on compression
stroke, the TTX design is superior.
The TTX Flow shock absorbers are
designed to handle the demanding damping
characteristics needed for all types of surfaces.
For best performance, the shock absorber must
be adjusted to different driving conditions; for
the smooth and fast gravel roads in Finland or
the rougher roads in Greece or in the Middle
East. Temperature stability is maintained by
a ow restriction design in the bleed valves
that creates a turbulent ow at very low piston
velocities. Also, materials with different thermal
expansion rates are used to compensate for the
viscosity change of the uid caused by changes
in temperature.
In addition the Öhlins shim system offers
innite combinations of shim stacks, with a wide
spectrum of different character using the same
piston. The whole system is pressurized by
nitrogen gas behind a oating piston to ensure
separation of the gas and uid.
The Öhlins TTX Flow shock absorber are racer
friendly shock absorbers, easy to set up, dial in
and rebuild. Remember that you can always get
support from the Öhlins dealers worldwide.
