About This Product
This TRW 11.8-inch (300mm) floating brake rotor is built for riders who need reliable stopping power and excellent thermal management. The floating design utilizes a stainless steel outer ring and an aluminum inner to minimize heat transfer and prevent rotor distortion. This specific model features a wide 51mm brake pad surface and is ABE approved. It fits front left and right positions on 2015 to 2025 Softails (excluding the 2017 FXSE), 2006 to 2017 Dynas (excluding the 2017 FXDLS), and 2008 to 2025 Touring models. It is also compatible with 2009 to 2025 Trikes and 2014 to 2022 Sportsters, provided they use the standard 3.25-inch bolt circle mounting pattern.
Manufacturer part number: MSW509.
