Item Description:

Yamaha 5CU-16380-10-00 Push Lever Assembly (Clutch Actuator Arm / Release Lever)

Genuine OEM Clutch Push Lever for Yamaha YZ250 and YZ250X Motocross/Off-Road Bikes

This is an authentic Yamaha replacement push lever assembly, also known as the clutch release arm, actuator arm, or clutch push lever. It mounts on the left side of the engine case, pivots to actuate the clutch push rod, and transfers motion from the clutch cable (or hydraulic system) to disengage the clutch plates for smooth shifting, starting, and control. Critical for reliable clutch operation in high-performance two-stroke dirt bikes.

Key Specifications:

• Part Number: 5CU-16380-10-00
• Type: Complete push lever assembly (includes lever arm, pivot shaft/bushings where integrated, and mounting provisions)
• Material: High-strength steel/aluminum construction with corrosion-resistant finish for durability in mud, dust, and vibration-heavy off-road use
• Design: Precision-machined pivot point and actuation surface for accurate clutch release; includes provisions for cable attachment and return spring hookup

Compatibility:

Direct OEM replacement for Yamaha YZ250 (two-stroke) and YZ250X models spanning a wide production range. Confirmed fitment includes:

• Yamaha YZ250: 2000–2011, 2013–2026 (including current models like 2025/2026 YZ250)
• Yamaha YZ250X: 2016–2026 (cross-country variant)

This part has remained consistent in design across these years in the clutch group diagrams. It is specific to models using this style of external clutch actuator arm.

Important Fitment Notes:

• Does not fit pre-2000 YZ250 models (which used different part numbers and designs)
• Not compatible with four-stroke Yamaha models (e.g., YZ250F, WR250F), YZ125, or other series unless explicitly cross-referenced in Yamaha parts catalogs
• Always verify your bike's exact model year and clutch diagram (available via Yamaha dealer, official parts finder sites, or service manual) to confirm. Compare the existing lever for shape, pivot location, and cable attachment points.

Features and Benefits:

• Restores crisp, precise clutch engagement/disengagement to prevent slipping, dragging, hard shifting, or incomplete release
• Addresses common wear issues like bent levers, worn pivots, or damaged actuation surfaces from crashes, chain slap, or prolonged use
• Maintains factory clutch feel and performance, essential for motocross racing, trail riding, or enduro events
• Built to Yamaha's exact OEM tolerances for perfect fit, smooth operation, and longevity under extreme conditions
• Often replaced during clutch rebuilds, cable changes, or after tip-overs that bend the arm

Condition: New – Genuine Yamaha part, unopened packaging

Installation Note: Replacement is a moderate DIY task but requires partial clutch-side access:

• Drain transmission oil if needed for access
• Remove clutch cable/perch, any guards, and pivot bolt
• Install new lever (torque pivot bolt to spec, typically ~7-10 ft-lbs with Loctite per service manual)
• Reattach return spring and cable, then adjust free play
• Refill fluids and test clutch operation Refer to the Yamaha YZ250 service manual for model-year-specific steps, torque values, and safety precautions. Professional mechanic assistance is recommended if you're not experienced with dirt bike clutch systems to avoid misalignment or damage.
