Cannondale motorcycle ohlins shock 用户手册

All motorcycles are designed with a suspension
geometry that includes height and fork angle. The
changing of components can affect this and it is
therefore essential that both the rear and the front
ends match each other.

Changing to Öhlins suspension gives optimum

performance only when both the front fork and
the rear suspension interact properly. It is of the
greatest importance that the front and rear loaded
height are within the specified values.
In the mounting instruction, see section: Setting
the spring preload.

Most of the Öhlins shock absorbers are of the De
Carbon type (Fig.1). The fluid is put under gas
pressure and the gas and the fluid are kept apart
by a separating piston. The separating piston is
often fitted in a separate fluid chamber, connected
by hose (1), or fixed direct on top of the shock
absorber (piggyback) (2).

There are also cases where everything is fitted

inside the main shock absorber (internal gas
reservoir) (3).

The most advanced shock absorber has twin

pistons. This ensures position sensitive damping
in relation to the degree of compression. One of
the pistons is active throughout the entire lenght
of stroke, while the second piston begins to work
in the event of powerful compression of the shock
absorber (4)

Pressurization of the fluid is made with nitrogen.

The pressurization prevents cavitation of the fluid
and the shock absorbing action is therefore more
even. The external fluid chambers also contribute

to better cooling of the fluid, giving longer service
life for both the fluid and components.

Öhlins shock absorbers have integrated

temperature compensation. As the temperature
increases and the fluid flows more easily the flow
is controlled accordingly. The shock absorbing
effect is therefore independent of the temperature.

The more advanced models permit individual

adjustment of compression damping and rebound
damping.

Öhlins shock absorbers provide the possibility

for adjustment, making them adaptable to most
motorcycles, riders and ranges of use. All of the
shock absorbers have adjustable preloading of the
spring action (Fig.2).
A few models have an adjustable end eye, mak-
ing it possible to alter the lenght of the shock
absorber 12mm (Fig.3).
