sprocket; continue until the end of the new chain is on the rear sprocket.
3. Remove the old chain, leaving the two ends of the new chain on the lower branch.
4. Assemble the new link to be riveted, ensuring that the 4 O-rings provided are fitted in the
proper locations.
NOTE
In the specific case of Regina chains, special O-rings can be used which, in addition
to guaranteeing a better sealing of the lubricant, are handed so they must also be
installed in a specific direction.
The two special O-rings to be inserted on the master link must have the protruding
side facing the master link plate, as shown in the figure:

General Information on Roller Chains
The chains that are installed on the Ducati models are roller chains designed according to
ISO/DIN/BS standards and are made up of alternating internal links and external links,
connected together by pins.
The internal links (3) are made of two plates fastened to each other through two bushings (2);
each bushing houses a roller (1).
The external links (4) are made of two external plates fastened to each other through two
pins (5) and four O-rings (6). The O-Rings have a twofold role as they not only hold the
lubricant but also avoid that any foreign objects enter the pin-bushing area.
This type of chain is characterized by two key parameters:
•
pitch length
•
link internal width
A standardized 3-digit numerical code is used to indicate these two values (for example: 415,
420, 428, 520, 525, 530).
NOTE
For the Regina chains, different references are used compared to international coding
standards.

According to the international coding standard, the first digit is the chain pitch (P), defined as
the distance between centers of two consecutive pins.
The chain pitch is calculated by multiplying 1/8 of an inch by the first of the three numbers
punched on the link (520):
P = 1/8” x 5 = 5/8” Therefore it is a chain featuring a 5/8” pitch.
To obtain pitch in centimeters, it is necessary to multiply the obtained value in inches by the
conversion factor 2.54:
P = 5/8” x 2.54 = 1.5875 cm ➔ 1.59 cm.
Below is a table summarizing chain pitch values.
Regina standard
International standard
Chain Pitch
135 – 136 – 136.2 – 137
520 – 525 – 530 – 532

Final Drive Chain Maintenance Precautions
All Models and Model Years (except XDiavel)
Service Repair Bulletin SRV-SRB-23-037
The second and third numbers according to the international coding standard, are the internal
width (W) of the chain. The higher this number, the higher the distance between the two
internal plates.
Internal width is calculated by multiplying 1/8 of an inch by the second and third digits (520)
after adding a decimal separator between the two digits (2.0 – 2.5 – 3.0).
W = 1/8” x 2.0 = 1/4” = 1/4” x 2.54 = 0.635 cm.
For example, a 530 chain, pitch is the same but width is different, i.e.:
W = 1/8” x 3.0 = 3/8” = 3/8” x 2.54 = 0.952 cm.
WARNING
Changing the internal distance between the links will change the space available for
the teeth of the sprockets so it is always mandatory to ensure that the coupling
between chain and sprockets always has the same characteristics.
It is NOT possible to install a 520 chain on 530-pitch sprockets or vice versa.
Statistically, it has been found that the average service life of a final drive chain is about
20,000 km, as long as it is periodically maintained in accordance with the instructions given in
the Owner's Manual of the motorcycle.
To ensure top performance and long life of the chain, we ask you to follow the instructions
relating to washing, lubrication, inspection and tensioning of the chain described above.
