Spring for personalised settings
Note
To adapt the rear shock absorber spring to the user it
is possible to order two types of spring as spare parts:
- for a user's weight of nearly 120 Kg we recommend the
spring with part no. 36640321A;
- for a user's weight of nearly 150 Kg we recommend the
spring with part no. 36640331A.
The recommended assembly according to the weights
specified above foresees a handgrip/pre-load press set to
zero so as to have 10 other mm pre-load available.
Warning
Contact a Ducati authorised dealer to order and fit the
springs.
