Dear Dealers,
This service campaign affects 2 vehicle components: the rear sprocket, and the DQS harness.
Part 1: During quality inspections performed after production, it was discovered that bushing
part no. 71210181A may not have been installed on the rear sprocket Z43 with the first batch of
bikes shipped.

Bushing part no. 71210181A

This Service Campaign requires inspection for the presence of bushing part no. 71210181A on
the rear sprocket and to install it if missing.
If this bushing is missing, it does not affect the bike operation for the first period of bike use.
Part 2: For the Hypermotard 950 SP and all Standard models with Ducati Quick Shift up/down
(DQS) installed as an accessory, it is necessary to apply a black heat-shrinking sheath or
similar product in PVC HT 105°C on the DQS (Ducati Quick Shift) sensor cable.

Service Solution
NOTE
To ensure the correct execution of the operation within the provided labor time to carry
out the updates, it is necessary to follow the sequence indicated in the following
instructions
Part 1: Checking the bushing on the rear sprocket
1. Put the front wheel in a vice and make sure it is securely mounted. Use retaining straps if
necessary.
2. Working on the motorcycle left side, remove the clip (1) and the nut (2) with the relevant
washer (3) that fix the flange-rear sprocket assembly to the rear wheel shaft.

the rear wheel shaft in order to perform a visual inspection as shown in the figure
NOTE
To perform the visual inspection position the spacer (4) on the chain tensioner
eccentric to move it away from the flange-rear sprocket assembly

- If the bushing (5) is missing, the assembly is NON-CONFORMING and it is
necessary to install the missing bushing. Follow the instructions in Part 2

- If the bushing (5) is present, the assembly is CONFORMING; perform the
reassembly procedure beginning from Part 2 - Step 6
