It fits a variety of late-model Softails, including the 2025 FLFB, 2021 to 2024 FLBS, 2021 to 2022 FXBRS, 2023 to 2025 FXBR, and the 2021 FXST. Listed as part number 917667, this sensor provides the precise feedback your engine management system needs to keep your bike running at its best while preventing trouble codes and poor fuel economy.
