AELLA Clutch Slave For the Ducati Panigale / Streetfighter / Diavel V4

28mm Clutch slave, 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, available in your choice of 3 beautiful anodized finish combinations! Original piston size is 22mm in diameter, resulting in fatigued hands and forearm pump. Aella'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.
