Ceramic Composite brake pads are extremely quiet, and deliver exceptional braking performance over a wide range of driving conditions. The Ceramic Composite braking material provides extreme stopping power when "cold" – right out of the driveway, or "hot" – after miles of all-out mountain highway. Ceramic Composite material is formed using high-strength ceramic fibers and non-ferrous metal filaments bonded at extreme pressure and temperature. Ductile metal-filaments produce a friction material with moderate base CoF (coefficient of friction) for optimal initial "bite", while durable heat resistant ceramic fibers and polymeric binders reduce thermal pad decomposition and out-gassing that contribute to high temperature brake "fade". The non-ferrous metal filament matrix provides high thermal mass and ideal thermal conductivity to quickly conduct energy away from the pad-rotor interface for fast thermal recovery. Lower operating temperatures reduce rotor wear and risk of deformation or warping
Full-metallic HH Sintered Bronze brake pads deliver exceptional braking performance under the most demanding conditions – from stunt or street-race riding, to extended high-speed highway or road-race driving. Sintered pads also perform exceptionally well in wet or muddy conditions, making them an excellent choice for off-road and MX (moto-cross) applications. Sintered bronze brake pads are manufactured using a high-pressure, high-temperature, pressed powdered-metal technology to produce a high density friction material with a high COF (coefficient of friction) across the full range of operating temperatures. The non-ferrous metal filament matrix provides high thermal mass and ideal thermal conductivity to quickly conduct energy away from the pad-rotor interface for fast thermal recovery. Lower operating temperatures reduce rotor wear and risk of deformation or warping.
I would go with Kevlar organic pads for a street bike.
Kevlar Organic brake pads are perfect where extremely smooth braking performance is desired. These bonded organic pads deliver solid braking performance under normal to aggressive riding conditions. Semi-metallic organic brake pads are manufactured using high-strength polymer binders, Kevlar (aramid) fibers, non-asbestos organic materials and fine metallic particles to form a medium-hard matrix with high durability, good thermal-conductivity and excellent frictional characteristics.
