These brake pads are the latest evolution of the Brembo street bike pad compound for P2 F09 brake calipers. These pads are optimized for road use to provide excellent performance while hot, cold, wet or dry, giving predictable feedback and a long service life. On Moto Guzzis, the F09 calipers were most commonly found as original equipment on the rear of 1000SP NT motorcycles, on BMWs they were used on R100 and R80 GS. However, F09 calipers with their large 48mm pistons have long been used to update motorcycles originally equipped with the P2 F08 caliper (38mm pistons) so it's best to confirm your caliper type before ordering.
