12/8 Piston Big Brake Kit for S1200/S800

The SAVANINI’s S1200 caliper is the caliper with the most pistons in the current mass-produced calipers. It adopts aluminum alloy forging technology and has high rigidity, high tensile strength, high toughness and high density. Compared with cast aluminum alloy calipers, the rigidity of the SAVANINI’s caliper has increased by about 50%, which effectively reduces the risk of caliper breakage during application. Compared with ordinary external dust covers, the built-in double oil seal design makes the brake feel and reaction speed more sensitive. It has excellent braking performance. After anodizing, vacuum coating CVD color fixation effectively solves common problems such as paint cracking and paint shedding, giving it a metallic texture and brilliant color. After installation, the entire wheel hub looks more attractive, perfectly coping with various road conditions, whether it is daily travel or sightseeing, it can also go on the track.

S1200What is unique about the  caliper?
One of the calipers with the most pistons independently developed and produced in China, with more and larger pistons and better linear feel. After multiple rigorous tests, its performance is about 35% higher than that of the original caliper. When matched with performance brake pads, it can meet the needs of intense driving in various environments, and can easily cope with special environments such as mountain roads and racetracks.
