CYGNUS Clutch Bell

Textured inner face & vented design—steady engagement, OEM-fit geometry.

The CYGNUS Clutch Bell is built to Ø131.5 mm OD / Ø120 mm ID for Yamaha CYGNUS applications. A micro-textured (sandblasted) inner working face helps the shoes bite cleanly, while vent/ejection holes promote dust purge and airflow to keep engagement consistent through heat cycles. At 690 g, the bell supports smooth takeoff when paired with appropriate springs and variator tuning.

🔹 OEM-Fit Dimensions — Ø131.5 mm OD / Ø120 mm ID for stock-layout compatibility
🔹 Textured Inner Face — Sandblasted surface aids clean bite, reduces slip/chatter, resists glazing
🔹 Vented / Ejection Holes — Promote dust evacuation and cooling for steadier feel over repeated stops
🔹 690 g Bell Mass — Provides inertia for smoother drive-off with matched springs/rollers
🔹 Precision Roundness — Concentric running surfaces for consistent shoe contact
