PURPOSE: To inform dealers of a seat support cable issue with the initial shipment of Switchback Seats (Part No. 52000655) that will require a replacement with Seat Support Cable (Part No. 52100087). In the initial shipment of Nightster Switchback Seats, the seat support cable used to limit the seat opening while accessing the fuel tank was installed to the seat in the incorrect location. Compared to the stock seat, this creates a reduction in available space to access the fuel tank.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10252820-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10252820-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10252820","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null},{"id":"seats","name":"Seats","parent":null},{"id":"fuel-tank","name":"Fuel tank","parent":"fuel-system"}],"codes":[],"topics":[],"vehicles":[{"make":"HARLEY-DAVIDSON","model":"RH975","year_from":2022,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"HARLEY-DAVIDSON","model":"RH975S","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
