It allows you to map the first part of the lever travel by adjusting the free travel. The RCS Corsa Corta allows you to calibrate this parameter on three positions (R-S-N), to obtain the maximum feeling of the braking attack. In the R "Race" position the free travel is minimized, the lever will be more reactive, in the S "Sport" position the free travel is in an intermediate position, as is the feeling at the lever, in the N "position Normal" the free travel is greater, therefore there will be greater modulation and a smoother braking attack. It allows you to change the wheelbase in two positions: 18 mm, for maximum modulation and 20 mm, for maximum braking readiness. Technical characteristics: the pump body is forged and CNC machined, hard oxidized, the brake lever is articulated and there is a stop light switch. The mechanical stop light switch fitted as standard on this pump allows the stop light to function correctly and therefore for road use. It is possible to remove it. The switch works with the lever at rest in "normally open" conditions, pressing the lever closes the circuit. It cannot replace switches that work "normally closed", for example BMW, in these cases it is necessary to purchase an optional switch. It can be mounted on twin-disc systems with floating type calipers (naked) or single-disc system (motard). The hardware for the brake hose fittings is not present in the kit and must be purchased separately if the original one is not compatible.
