Arlen Ness 14″ Full-Floating Big Billet Brake Rotor For Harley Touring 2014-2025
Unrivaled Braking Performance: Arlen Ness 14″ Big Brake Billet Rotor Kit
When you are piloting a modern Harley-Davidson Touring machine—often weighing over 800 pounds—the ability to stop quickly and confidently is paramount. The Arlen Ness 14″ Full-Floating Big Brake Billet Rotor Kit is specifically engineered for 2014–2025 models to provide the most cost-effective and dramatic increase in braking performance available on the market. By drastically increasing the rotor diameter, Arlen Ness has applied the law of physics to motorcycle braking: a larger diameter equals more leverage, and more leverage means shorter stopping distances with less effort at the lever.
The Power of 14-Inch Leverage
Modern Harley Baggers come standard with 11.8″ (300mm) rotors. While adequate for casual cruising, they can struggle under the heat and stress of heavy touring or aggressive riding. The Arlen Ness Big Brake Kit steps up to a massive 14-inch (355mm) diameter. This increase in size provides approximately 30% more leverage than stock. This means you can achieve the same stopping force with significantly less finger pressure on the brake lever, reducing hand fatigue on long rides and providing a much more “sportbike-like” tactile response during emergency braking situations.
Full-Floating Technology for Extreme Heat
Performance is nothing without consistency. The Arlen Ness Big Brake Kit features a Full-Floating design, consisting of a high-carbon 420 stainless steel outer friction ring connected to a 6061-T6 billet aluminum inner carrier. In a heavy-duty braking event, the outer ring can reach extreme temperatures and expand. Because it is a floating design, the ring can expand independently of the hub, preventing the warping, cupping, and “pulsing” that often plagues solid-mount factory rotors. This ensures that your brake lever remains perfectly smooth and your stopping power remains 100% consistent, even after a heavy descent down a mountain pass.
Retain Your Factory Brembo Calipers
One of the most brilliant aspects of the Arlen Ness 14″ kit is that it allows you to keep your high-quality factory 4-piston Brembo calipers. The kit includes a precision-engineered, CNC-machined caliper relocation bracket that moves your stock caliper outward to accommodate the larger diameter rotor. This saves you the thousands of dollars required for aftermarket calipers while still providing a massive leap in performance. It is the perfect “sleeper” upgrade that looks like a custom show piece but performs like a race-track component.
Iconic Ness Styling and Fitment
The “Billet” series features a clean, high-tech aesthetic that complements the modern lines of the Street Glide, Road Glide, and Road King. The inner carrier is finished to a high standard, adding a custom, high-end look to your front end. This kit is designed to fit 2014–2025 Touring models equipped with factory 17″, 18″, or 19″ front wheels (and most aftermarket wheels). It is a direct bolt-on installation that requires no permanent modifications to your motorcycle.
- Touring Models (2014–2025): Fits Street Glide, Road Glide, Road King, and Electra Glide Ultra Limited.
- Caliper Compatibility: Designed for factory 4-piston Brembo calipers.
- Wheel Requirement: Must be used with 17″ diameter or larger front wheels.
Installation Note: Maximum Results
To ensure the best results and a proper bed-in process, Arlen Ness and Twin Power recommend installing brand new brake pads with this rotor kit. Using old pads with a new friction surface can cause uneven wear and reduced performance. Due to the high-friction stainless steel used in this kit, it is compatible with Organic, Semi-Sintered, and Sintered compounds. Always use the provided hardware and ensure all bolts are torqued to factory specifications with the appropriate thread-locker.
Choose the Arlen Ness 14″ Big Brake Billet Rotor Kit for your Harley Touring model if you demand the absolute best in stopping power, cooling efficiency, and custom style.
