SIP 4-piston brake calliper for Vespas

With the braking performance of the standard Vespa 2-piston brake calliper being widely regarded as " rather sluggish ", SIP Scootershop in Germany has introduced this new CNC machined billet aluminium 4-piston brake caliper for Vespa GTS / GTS Super / GTV / GT 60 / GT / GT L 125-300cc models ( also suitable for GILERA / PIAGGIO DNA / Runner VX / VXR / Super Hexagon GTX 125-200cc ). " At the least , when demanding riding manoeuvres and high loads are applied to the OEM brake calliper , it definitely reaches its limits " says CEO Ralf Jodl . " Our SIP Series Pordoi brake caliper gives the scooter a sporty upgrade and maximum performance in terms of braking and safety ." Suitable for use with the standard master brake cylinder , the EU Homologated ( ABE approved ) SIP design features 2 x 34 mm and 2 x 30 mm pistons - meaning that the ratio of braking energy transmission to the disc is optimised , guaranteeing a significantly improved braking performance . " In addition , we have given the brake calliper a GALFER brake pad with a larger pad width and tilt-proof contact surface . The large surface area ensures improved heat dissipation , and this results in a longer service life , both under continuous load ( passing ) and in terms of pad wear . The brake callipers are anodised and come in black or silver with a milled SIP logo .
