Manual Slave Cylinder Kit / '13-'16 Models

Rekluse's billet replacement slave cylinder, cutting clutch lever effort by more than 20 percent on a hydraulic clutch Harley-Davidson.

A hydraulic clutch lever feels heavy because of the ratio between the master cylinder and the slave, and on a big twin that ratio was chosen for packaging rather than for your hand. Rekluse machines this slave from billet aluminum and hard anodizes it, then changes the ratio so the lever pulls over 20 percent lighter. The side effect is the part riders actually notice: the friction zone gets wider and the engagement point moves closer to the bar, so slow speed work in traffic stops being a wrestling match with a two finger pull.

Common Questions About the Rekluse Slave Cylinder

Does a lighter pull mean the clutch slips sooner?
No. The clutch pack and its spring are untouched. This changes the hydraulic ratio between your hand and the pushrod, so clamping force at rest is exactly what it was.

Do I have to bleed the system?
Yes. Opening the slave opens the hydraulic circuit, so it needs bleeding and a fluid top up afterward.

Is it worth it with a stock clutch?
Yes. It is a direct OEM replacement and works with the stock pack. Rekluse notes you can take the pull down further by running it alongside a TorqDrive clutch, but that is an addition, not a requirement.
