Introduction
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.
A careful observer, Kenth’s attention was
continually drawn to one specific 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 first
World Championship title. Despite being in the
business for 30 years, the search for perfection
and new functions is still the main focus of the
company.

Design and Functioning
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 two
decades of Öhlins successful participation in World
Championship events.
This shock absorber draws on all the
expertise developed by Öhlins while winning
more than one hundred World Championship
titles.
The Öhlins TTX features a patented concept
with a unique concentric twin tube design,
together with a solid main piston, that allows
for the gas pressure to always back-up the lowpressure side of the main piston. This design
creates positive pressure buildup 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.
Compared to a regular piggy back single tube
shock absorber, that has positive pressure
buildup 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.
Also, the twin tube design with separate
channels connecting the compression valve
to the compression side of the main piston
and the rebound valve to the rebound side of
the main piston gives the possibility to have
completely separated adjusters for compression
and rebound damping.
The whole system is pressurized by
nitrogen gas behind a oating piston to ensure
separation of the gas and uid.
The Öhlins shim system offers innite
combinations of shim stacks with a wide
spectrum of different character.
The Öhlins TTX shock absorber is a user
friendly shock absorber, easy to set up, dial in and
rebuild. Support is always available from the Öhlins
distributors worldwide.
