Performance Machine 11.5″ Rear Brake Rotor For Harley-Davidson (2000–2017)
High-Friction Stainless Steel & Custom CNC Machined Stopping Power
Upgrade the rear braking performance and rear-wheel aesthetics of your Harley V-Twin with the Performance Machine 11.5″ Rear Brake Rotor. Precision-engineered for 2000 through 2017 Harley-Davidson Dyna, Softail, Touring, and Sportster models requiring an 11.5-inch rear rotor setup, this high-performance brake disc offers optimal thermal dissipation and exceptional lever feel.
Precision-ground from high-carbon 420 stainless steel, PM rotors undergo rigorous heat treating to eliminate warping, disc dishing, and brake fade under aggressive braking conditions. Whether paired with stock single-piston or multi-piston aftermarket calipers, the drilled friction ring pattern cleans pads effectively while keeping heat build-up controlled during extended highway braking or aggressive street riding.

Braking Dynamics & Stainless Steel Engineering
### Precision Surface-Ground Stainless Steel
Unlike cheap stamped steel rotors that warp easily under heavy heat cycles, Performance Machine rotors are precision laser-cut and double-disc surface ground to exact flat tolerances. This guarantees parallel friction surfaces, eliminating brake lever pulsation and uneven pad wear. The drilled outer ring reduces rotating unsprung weight while sweeping water and gas build-up away from the pad contact area.
### Exceptional Custom Style & Compatibility
Performance Machine designs their rotors to pair flawlessly with custom wheels or factory Harley hubs. Featuring PM’s distinctive spoke cutouts and polished stainless steel finish, this 11.5″ rotor transforms a plain rear brake assembly into a highlighted custom focal point on your bike’s drivetrain side.
Vehicle Compatibility Guide
Performance Machine 11.5″ Rear Brake Rotors offer direct bolt-on replacement for 2000–2017 Harley-Davidson V-Twin models equipped with standard 11.5-inch rear rotors:
### Compatible Harley-Davidson Models (2000–2017)
- Harley-Davidson Dyna: FXD, FXDB, FXDL, FXDF, FXDWG (2000–2017)
- Harley-Davidson Softail: FXST, FLST, FXSB, FLS (2000–2017)
- Harley-Davidson Touring: FLHX, FLTR, FLHT, FLHR (2000–2007) (Note: 2008–2017 Touring models use 11.8″ rear rotors)
- Harley-Davidson Sportster: XL 883 / 1200 models (2000–2010)
Fitment Note: Designed for wheels with 2.22″ center hub locator registers (standard 2000–2017 Harley fitment). Verify bolt hole hardware thread pitch when installing with aftermarket custom wheels. Always replace rotor bolts and install fresh organic or sintered brake pads when fitting new rotors.
Step-by-Step DIY Installation Overview
Installing a Performance Machine rear brake rotor is a standard bolt-on mechanical task. Estimated installation time: 45 to 90 minutes.
### Required Tools
- Motorcycle Center Frame Lift / Jack
- 3/8″ Drive Torque Wrench
- Torx / Allen Socket Set (for rear rotor bolts and axle adjustment)
- Blue Threadlocker (Loctite 243) and brake cleaner spray
### Step 1: Motorcycle Preparation & Rear Wheel Removal
Elevate the motorcycle safely on a center frame lift until the rear wheel is off the ground. Loosen the rear axle nut, back off belt/chain adjusters, unbolt the rear caliper bracket, and carefully slide out the axle to remove the rear wheel assembly.
### Step 2: Removing Stock Rotor & Mounting PM Rotor
Unbolt the five original rear rotor bolts and clean the hub mounting face to ensure a perfectly flat seat. Position the PM 11.5″ rear rotor over the center hub register. Apply blue threadlocker to new grade-8 rotor bolts and hand-thread them into the hub.
### Step 3: Final Torque & Brake Realignment
Torque the rotor bolts in a crisscross star pattern to 30–35 ft-lbs (or manufacturer recommendation). Reinstall the rear wheel assembly, align belt tension, install fresh brake pads into the caliper, and reinstall the rear caliper. Pump the rear brake pedal to restore hydraulic pressure and perform a slow-speed test ride to break in the new friction surface.
Frequently Asked Questions
### Will this 11.5″ rotor fit my 2008-2017 Harley Touring model?
No. Harley Touring models (Street Glide, Road Glide, Electra Glide, Road King) switched from 11.5″ rear rotors to larger 11.8″ (300mm) rear rotors starting in 2008. If you own a 2008–2017 Touring model, you will need an 11.8″ PM rear brake rotor.
### Should I replace my brake pads when installing a new rotor?
Yes. Installing new brake pads alongside a new rotor is strongly recommended. Used brake pads develop uneven wear grooves from your old rotor, which can score the surface of your new PM stainless steel rotor and reduce initial stopping performance.
