EBC Double-H Brake Pads

EBC Double-H brake pads are the true and undisputed king of fast motorcycle brakes. Within one year of their launch in 2004 these pads became the standard by which all brake pads for street bikes were judged because of their long lasting and powerful brake effect. Double-H sintered brake pads benefit from the highest friction HH rating for maximum stopping power, and are manufactured from sintered copper alloy like original pads, for longer life and perfect braking. Stainless steel radiator plates are fitted to the pads to reduce heat transfer into your bikes hydraulics where required. The unique double segment vented design of EBC Double-H pads improves braking under all riding conditions--wet, dry, hot, or cold!

Twin Power X-Stop Sintered Brake Pads

Every type of brake pad has a specific upside, but Twin Power X-Stop sintered brake pads could fill a notepad with features. To begin, they're constructed from hardened metallic alloys, solidified through temperature and high pressure. While they may have a longer "break-in" period than resin pads, sintered versions typically last longer and provide maximum braking ability. These brake pads carry an HH friction rating, meaning they'll operate efficiently in both hot and cold environments--in fact, they're ideal in wet, muddy, or dusty conditions. If you're a heavier rider, the sintered pads are likely a better option than an organic compound. Twin Power X-Stop sintered brake pads are ready to ship for Harley-Davidson® bikes, in particular, such as Touring, Softail, Dyna, FXR, FX, Sportster, and V-Rods … with replacements for 1972 and later models. Just locate the fitment for your wheels, and hit the brakes with confidence!

Twin Power Brake Pads

The need for speed should always be counterbalanced with the ability to stop. Twin Power brake pads are at the apex of your motorcycle's braking system, enabling smooth deceleration without noise or metal-on-metal grinding. These pads are made from premium organic materials which dissipate heat and extend the overall life of your brakes. Because of their low-abrasion factor, these are the preferred pad compounds for polished and stainless steel rotor applications, though they're compatible with any type of rotor material. How often should you replace brake pads? Many riders report going 15,000 miles between changes, but it all depends on your riding and braking style. If you see noticeable wear, or if a pad is wearing unevenly, it's wise to make the economical upgrade for your safety and to protect more expensive brake components. Twin Power brake pads are available for Harley-Davidson® models, in particular, including Touring, Softail, Dyna, FXR, FX, Sportster, and V-Rods … some dating as far back as 1972. Find the pads to fit your bike--and experience an exceptional "stop" when you're finished in the fast lane.
