The Accossato radial clutch master cylinder is made of aluminium and natural anodising. The piston diameter is 14 mm. The distance is adjustable between 15-16-17 mm: Suitable for all uses because you can adjust the distance according to the situation of use. The lever is available in black, short or long, with relieving eyelet (RST) or without (NRST). The radial clutch master cylinder is completely Made in Italy; the screws are made of stainless steel, the bleed valve is made of galvanised steel and the seals are made of Formula 1 compound. There is an offset riser to reduce pump flex during shifting. Each component is designed to ensure the shortest passive lever travel: when the lever is pulled, the gap between lever activation and actual shifting is reduced by more than 50%, compared to any other radial master cylinder. The screw pitch for mounting the hoses is M10x1. The brake light switch is not included: it can be purchased separately under part number ID001 or ID002. The fluid reservoir is not supplied with the clutch master cylinder, but can be purchased separately by choosing from various models.
