Service bulletin 1HDR6U9Z11

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 M1455: 2018 SOFTAIL MILWAUKEE-EIGHT 107 - CLUTCH PACK. Purpose: This bulletin informs dealers of a running change from a 9-plate clutch pack to a 10-plate clutch pack on 2018 Softail® models with a Milwaukee-Eight® 107 engine. When replacing any Milwaukee-Eight 107 Softail clutch pack, the 10-plate clutch pack is the correct fitment for the service part. Do not attempt to order a 9-plate clutch pack, it is not available. Do not mix components of 9-plate and 10-plate clutch packs as parts are not interchangeable.
