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 bypass valve within the front suspension and occurs when switching between compression and rebound. The sound can be amplified by the fender shape on some motorcycles. The sound does not affect the performance of the motorcycle. Indian Motorcycle has released a service kit with new upper fork with a revised bypass valve to correct the noise.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10209966-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10209966-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10209966","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"INDIAN","model":"CHIEF","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"CHIEF BOBBER","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"INDIAN","model":"SUPER CHIEF","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
