Reduce your lever effort with CNC Racing's clutch slave cylinder for your Ducati. CNC machined from light billet alloy and then given a colored anodized surface finish and a beautiful "race-style" look. Featuring improved hydraulic seals to prevent leaks and increase durability, and available with your choice of a 26 (link below), 28, or 30mm piston size, and available in your choice of 3 beautiful anodized finishes. Original piston size is 25mm in diameter, resulting in fatigued hands and forearm pump. CNC Racing's larger diameter clutch slaves reduce lever effort by over 25%, and the bigger the piston, the easier the lever pull. The only drawback to a larger clutch slave is you do technically have to pull the lever in slightly further to engage the clutch to the same extent as with a smaller piston, so if you prefer shorty levers, we recommend the 26 (link below) or 28mm size (to avoid contact with your other fingers when pulling the lever in with only 2). If you are using standard length levers, we recommend the 28 or 30mm size. If you have upgraded your clutch to an aftermarket slipper clutch, choose the 28mm size for best results. Includes a 10mm Spacer for use with Ducati's made before 2001 and the Piston has slots for the new bikes that feature the "Anti Rotation" Pin
