About This Product
This black handlebar master cylinder assembly is a perfect match for Gen1 Touring riders looking for a dark custom look or a reliable replacement for a worn-out factory unit. It features a 15mm bore intended for dual disc front brake configurations. This assembly fits a wide range of 2008 to 2025 Touring models, with the exception of certain late-model editions like the 2023 to 2025 FLTRXSE or 2024 to 2025 FLHX. It is also compatible with 2008 to 2017 V-Rod models and various Trike years. Functionally equivalent to OEM 44551-08B, this master cylinder ensures your braking performance remains sharp while providing a clean, blacked-out aesthetic for your handlebars.
Manufacturer part number: 940537.
