Drag Specialties 11.8″ OEM-Style Brake Rotor For Harley Touring 2008-2016
Baggage-Grade Reliability: Drag Specialties 11.8″ OEM-Style Rotor
When Harley-Davidson updated their Touring lineup in 2008 to include the 4-piston Brembo braking system, they increased the rotor diameter to 11.8 inches (300mm) to handle the growing weight and power of the modern Bagger. The Drag Specialties 11.8″ OEM-Style Brake Rotor is a premium replacement disc designed specifically for this era. Whether you are replacing a warped rear disc or a thin set of front rotors, this unit restores the smooth, authoritative stopping power your Touring machine was born with.
The 300mm Standard: Precision and Power
Unlike older 11.5″ rotors, the 11.8″ diameter provides a larger friction surface and increased mechanical leverage. Drag Specialties manufactures these rotors from high-carbon 420 stainless steel, induction-hardened to withstand the extreme heat generated by heavy Touring loads. Each rotor is diamond-ground to an exacting tolerance to ensure a perfectly parallel surface. This precision eliminates the “lever shake” and “pedal pulse” that often occurs when factory rotors become heat-distorted over long miles.
Advanced Cooling and All-Weather Safety
This rotor features a classic drilled pattern that matches the aesthetic of the 2008–2016 Touring models while providing modern thermal management. The drilled holes serve as essential vents, allowing heat to escape the friction ring and preventing the “glazing” of brake pads. In wet weather, these holes act as a clearance path for water, ensuring that your 4-piston calipers can bite into the metal immediately without the dangerous delay caused by water film buildup.
Specific Touring Fitment (2008–2016)
This rotor is a direct bolt-on for the modern 300mm front and rear systems. It features the 2.22″ center hole and is compatible with your factory mounting hardware:
- Street Glide & Road Glide (FLHX / FLTR): 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016.
- Road King (FLHR): 2008–2016 models with factory 11.8″ discs.
- Electra Glide (FLHT): Ultra Classic and Limited models from 2008–2016.
- Position: Compatible with Front (Left or Right) and Rear applications on most 2008–2016 Touring frames.
Installation Tip: Complete the Service
Because Touring bikes are heavy and generate significant brake dust, Drag Specialties recommends installing new brake pads with every rotor change to ensure a clean bed-in. For maximum stopping power on these 300mm systems, pair this rotor with Sintered Metal pads. Always use new rotor bolts with blue thread-locker and torque to the factory-specified 16–24 ft-lbs for a safe and secure installation.
