Service bulletin M1571
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
SERVICE BULLETIN M1571: REVOLUTION MAX CLUTCH PART AND SERVICE PROCEDURE CHANGE. PURPOSE: This bulletin informs dealers that Harley-Davidson Revolution® Max clutches will be serviced by a clutch disc kit and not with individual plates. A new clutch disc service kit (Part No. 37000383) will be provided for making clutch repairs on all Revolution® Max powered vehicles moving forward. The procedure of replacing individual discs is no longer recommended. If one steel or fiber plate requires replacement, a clutch disc kit will need to be installed. Online Service Manuals located in Service Information Portal (SIP) and future printed copies will reflect this information. See https://serviceinfo.harley-davidson.com for the latest electronic version of the service manual.
