Service bulletin M1450
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 M1450: MILWAUKEE-EIGHT EQUIPPED VEHICLES - LOSS OF POWER OR HIGH ENGINE BRAKING. PURPOSE: REVISION. 2017 - 2019 model motorcycles equipped with a Milwaukee-Eight? engine can experience a condition known as sumping during extended periods at high rpm or under heavy engine load. Sumping is when an excessive amount of oil is suspended in the engine crankcase and the flywheel must travel through the oil, resulting in loss of power or a high degree of engine braking and potential engine component damage with extended use under these conditions. This bulletin provides the diagnostic procedure for determining if sumping is occurring.
