Dominant Stopping Power: Twin Power X-Stop Sintered Pads for Brembo Calipers

For the modern Harley-Davidson rider, the braking demands of a Milwaukee-Eight or late-model Twin Cam Touring bike are immense. With the introduction of high-performance 4-piston Brembo calipers, the potential for incredible stopping power is there—but you need the right friction material to unlock it. The Twin Power X-Stop Sintered Front / Rear Brake Pads are engineered to be the ultimate heavy-duty solution for 2008–2026 models. Whether you are navigating a loaded-down Ultra Limited through the Rockies or pushing a V-Rod to its limits, the X-Stop series provides the aggressive “bite” and thermal stability required for total control.

Advanced Sintered Metallurgy: Built for Heat

Unlike standard organic or semi-metallic pads, Twin Power X-Stop pads are created through a high-pressure sintering process. Metallic particles are fused together to form a friction block that thrives in high-temperature environments. For a heavy Touring bike, heat is the enemy of performance. Standard pads can “glaze” or soften when they get too hot, leading to a terrifying loss of braking force known as brake fade. The X-Stop metallic matrix acts as a heat sink, dissipating thermal energy quickly and maintaining a consistent coefficient of friction from the first stop of the morning to the thousandth stop of the day.

Aggressive Response and Shorter Stopping Distances

The hallmark of the Twin Power X-Stop series is its “initial bite.” The moment you apply pressure to the brake lever, these pads engage the rotor with mechanical authority. This rapid friction transition is essential for emergency stopping situations where every foot of distance counts. For riders who find the factory pads feel a bit “vague” or “soft,” the X-Stop upgrade provides a tactile, connected feeling at the handlebar and foot pedal. This increased efficiency allows for easier modulation under load, giving you the confidence to slow down an 800-pound machine with minimal effort.

The Long-Distance Choice: Extreme Durability

Touring riders and daily commuters need a pad that doesn’t just work well, but works for a long time. The sintered metal construction of the X-Stop series is significantly more resistant to abrasion than organic fibers. In high-mileage testing, these pads consistently outlast OEM and aftermarket organic alternatives, making them the most cost-effective choice for riders who put 10,000+ miles on their bikes annually. Furthermore, the metallic compound is impervious to oil and brake fluid contamination, ensuring that the integrity of the pad remains uncompromised over its entire lifespan.

All-Weather Reliability: Rain or Shine

Weather conditions can change in an instant, and your brakes need to be ready. Sintered pads are the gold standard for wet-weather performance. While organic pads can absorb moisture or allow a film of water to build up between the pad and rotor, the metallic X-Stop material “scrapes” the rotor surface dry instantly. This provides immediate, predictable stopping power in a torrential downpour, providing an essential safety margin for year-round riders and cross-country tourers.

Precision Fitment for 2008–2026 Models

These pads are a direct-fit replacement for Harley-Davidson OEM Part Number 41854-08. This pad shape is the standard for modern high-performance Harley braking systems:

• Touring Models (2008–2026): Fits Road King, Street Glide, Road Glide, and Ultra Limited (Front & Rear).
• V-Rod Models (2008–2024): Fits VRSCAW, VRSCDX, and VRSCF Muscle equipped with Brembo calipers.
• Tri-Glide / Freewheeler (2009–2026): Fits Front calipers only.

Installation and Technical Note

Twin Power X-Stop pads are high-performance metallic components. Because of their aggressive nature, they may produce a slight “whirring” sound and more visible brake dust than organic pads. They are designed for use with high-quality stainless steel rotors. To ensure maximum performance, we recommend a thorough cleaning of the caliper pistons before installation. A 100-mile “bed-in” period—consisting of gradual stops from 30 MPH—is recommended to allow the sintered material to mate perfectly with the rotor surface.

Choose Twin Power X-Stop Sintered Brake Pads for the ultimate combination of aggressive stopping power, long-distance durability, and all-weather safety.
