Clutches

Slipper clutch adjustable "Race"
FZA015

Lightweight slipper clutch with 6 Ergal springs (without spider spring)
Compatible with all Ducati models equipped with a dry clutch.

The kit includes:
• Ergal clutch coreboard
• Ergal clutch drum with 45° ball ramps
• Ventilated clutch pressure plate "Thunder" with slots to monitor disc wear
• 3 sets of spring caps (1.7/1.85/2.1) with different settings to adjust and customize engine braking and slipper control
• Stainless steel balls, screws and burnished springs
• High-speed bearing for the clutch pressure plate (already installed)
• Two retaining nuts machined from a single block, including the spring pressure flange
• One Belleville spring
• Ground spacer with O-ring to ensure perfect clutch parallelism

The clutch assembly is equipped with a 6-spring stainless steel loading system, replacing the conventional spider spring. The kit includes 3 sets of marked retaining cups, designed to vary the mechanical preload of the springs. By replacing or combining the different sets (configurable in symmetrical groups of 2 or 3 units), it is possible to modify the clutch calibration, optimizing the intensity of the engine braking and the intervention threshold of the slipper system based on the dynamic needs of the vehicle. The system setup is distinguished by its high efficiency and speed of execution: changing the calibration does not require disassembly of the clutch body or replacement of internal components.

Installation Instructions
Illustrated step-by-step instructions are available online and downloadable in PDF format.

The clutch can be installed using the original clutch basket (if in good condition) or combined with one of ours.
Compatible with original or racing discs.

The use of a slipper clutch offers numerous advantages, both on the road and on the track:
• Greater stability when braking and downshifting: prevents the rear wheel from locking or hopping during aggressive downshifts, improving safety and control of the bike.
• Smoother and more precise downshifting: reduces stress on the transmission and allows for faster and more confident downshifting.
• Less mechanical stress: limits rebound on the bell, gearbox, and crankshaft, extending the life of the components.
• Superior riding comfort: the bike remains more composed, especially during hard braking or sporty riding.
• Consistent performance: the system works progressively, ensuring a consistent and predictable response.

An ideal choice for those who want to improve the safety, feel, and performance of their Ducati.
