Service bulletin KTB2109

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

As a result of our active market monitoring and constant product improvement processes, we have determined that the items listed below on the 2021 1290 SUPER DUKE R should be inspected and updated in order to ensure the best functionality. 1. It is possible that the cables for the exhaust flap rest on the brake line for the rear brake. 2. Under frequent use, the screw connection on the housing of the spring preload handwheel may become loose. The instructions for points 1 and 2 are described below and on the following pages in detail. The deviations are not necessarily present on all vehicles; however, inspection of all vehicles is necessary.
