FRONT SUSPENSION
ADJUSTMENTS
Obtaining the maximum performance from your suspension system depends on
using the correct settings and making the proper adjustments. This section
describes how to properly set and make adjustments to your Marzocchi suspension
system.
In order to find the best settings for you, you will need to try several times to
understand where and how to make adjustments.
When doing so, please ride in an open area, free from traffic, obstacles and other
hazards.
The best settings not only depend on the Motorcycle frame geometry, the rider’s
weight and the types of trail or obstacles, but also on many other personal factors
connected with your riding style.
Therefore, it is not possible to provide you with objective information concerning
your desired settings.
Changing the settings on your suspension system must be done on only one
adjuster at a time, taking note of the modifications you carry out and the improvements
you obtain.
WARNING
During the setting operations, never force the adjusterspast their limits.
INITIAL SUSPENSION BOTTOMING ADJUSTMENT
Optimal spring hardness is that which reaches the required SAG, in other words, the
suspension is lowered solely due to the rider’s weight.
How to measure SAG
In order to measure the SAG, you only need to carry out the following steps: Pick
up the front of the motorcycle so that the wheel is off the round, measure the part
of the leg between the edge of the wheel axle clamp and the dust seal, then take note
of the value as “H1”.
• Repeat the measurement with the motorcycle in a vertical position with both wheels
on flat round then take note of the value as “H2”.
SAG = H1 - H2
The optimal SAG is equal to 25 - 40 mm (based on the motorcycling activity).
When you have a value that is lower than recommended, you must reduce the pre-
load or replace the spring with a “softer” one to obtain the best performance from the
suspension, vice versa when the value is higher it is necessary to increase the pre-
load or install a “harder” spring.
