# Service bulletin ISA\-24\-01

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 found that some 2022 and 2023 Chief models can exhibit a noise in the front of the motorcycle when operating slowly on rough or bumpy road conditions. The sound can be difficult to properly diagnose as it may resemble a metallic clicking in the front headlight area. The sound is coming from the rebound check valve within the front suspension and occurs when switching between compression and rebound. To address this, Indian Motorcycle has released this Service Advisory with instructions to install a new fork service kit that has an updated rebound check valve to correct the noise. This Service Advisory replaces ISA\-21\-01.
