SBS front motorcycle brake pads in "RST" compound for trackdays and racing. Front sintered compound with high brake performance. RST is the ideal choice for trackday riders and amateur club racers as it feels like a street pad but with a strong initial bite, handles high heat well and doesn't fade. Street use ok. Very popular choice amongst racers in AFM, CCS, WERA, FMRRA, and premier motorcycle trackday organizations nationwide. 2/pc per set (bikes with dual calipers will require 2 sets).
