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

Indian Motorcycle has determined that on MY23 Chief, Chief Bobber, Super Chief, and Sport Chief the speedometer may not display the correct vehicle speed until the engine speed first exceeds 1200 RPM while in gear following the initial key cycle. To address this concern, Indian Motorcycle has released this Service Advisory to instruct dealers to reflash affected vehicles with an updated Engine Control Module \(ECM\) Calibration.
