BLCYANUE 11.5" Front Brake Rotor for Harley Davidson — Mirror-Polished Stainless, Improved Cooling & Reduced Vibration

High-performance 11.5" front brake rotor by BLCYANUE engineered for Harley Davidson Touring, Sportster, Dyna, Softail and early Super Glide models to improve cooling, reduce vibration and deliver consistent stopping feel.

This mirror-polished stainless-steel rotor is designed to be a direct-fit brake upgrade for a wide range of Harley Davidson motorcycles from the mid-1980s through the early 2010s. Its full-sweep cut pattern and hollow construction help shed heat quickly, while precision grinding and a corrosion-resistant finish promote smooth operation and long service life. The rotor ships with the hardware needed to adapt common mounting sizes, but always verify compatibility with your specific bike year and model before installation.

How does this rotor handle heat and wet conditions?

The rotor uses a full-sweep cut pattern and hollowed sections to expose more surface area to airflow, accelerating heat dispersion during repeated braking. That helps reduce brake fade on steep descents or aggressive riding and maintains consistent friction in wet weather.

• Full-sweep ventilation channels for better airflow and cooling
• Hollow design reduces mass and speeds cooling cycles
• Polished stainless surface resists corrosion that can trap heat

Will this rotor reduce vibration and improve brake feel?

BLCYANUE rotors are precision ground to maximize flatness, which minimizes runout and vibration at the caliper. Heat-treated construction with added chrome hardness improves wear resistance so pad contact remains consistent over time, delivering a steadier lever feel and reduced pulsing.

• Precision-ground faces to limit lateral runout
• Heat-treated 420 stainless for wear durability
• Polished finish and balanced design to lower brake judder

Which Harley models and years fit this 11.5-inch rotor?

This rotor covers a broad selection of Harley Davidson motorcycles: Sportster models from 1984–2013, many Softail and Touring bikes across the listed years, Dyna models from 1992–2005 and early Super Glide years. Confirm your bike's rotor bolt pattern and diameter before ordering to ensure a precise fit.

• Sportster: all models 1984–2013
• Softail: multiple model years including mid-1980s and 1999–2014
• Dyna: all models 1992–2005; Early Super Glide: 1984–1991; Touring: 1984–2007

What comes in the box and what installation notes should I know?

The package includes the 11.5" mirror-polished 420 stainless rotor plus an adapter ring to change a 2-1/4" rotor mount to a 2" fit and the specified 5/16-18 x 3/4" screws for installation. Always inspect mounting surfaces, torque fasteners to manufacturer specs, and check clearances with your caliper and wheel before riding.

• Included adapter ring to convert 2-1/4" to 2" mounting
• Installation screws (5/16-18 x 3/4") supplied
• Verify bolt pattern, rotor width, and caliper clearance pre-install

Who is this for: Riders who want a durable, cooler-running front rotor for older and classic Harley models—mechanically inclined owners, custom builders, and restoration projects benefit most. Choose this rotor if you need improved heat management, reduced vibration and a corrosion-resistant polished finish built to fit a wide range of Sportster, Softail, Dyna, Touring and early Super Glide machines.
