Description de produit
Forged 4340 Steel Motorcycle Engine Connecting Rod
This forged 4340 steel motorcycle engine connecting rod is precision-engineered for high-performance motorcycle engines, including Honda CB series and Yamaha YZF models. Manufactured from premium 4340 alloy steel through a multi-stage forging process, it delivers exceptional tensile strength and fatigue resistance under extreme RPM conditions.
Key Features
- Premium Material: Forged from 4340 chromium-molybdenum steel for maximum durability and impact resistance
- Motorcycle-Specific Design: Optimized weight-to-strength ratio for motorcycle engine RPM ranges (8,000-14,000 RPM)
- Precision Machining: Center-to-center length tolerance of +/- 0.01mm; big end bore honed to H6 tolerance
- Heat Treated: Quenched and tempered to HRC 35-40 for optimal balance of hardness and toughness
- Shot Peened Surface: Compressive surface stress enhances fatigue life by 30% over untreated rods
- 14mm Piston Pin: Exact fit for common motorcycle engine piston pin diameters
