The SB200 Piston Pin is a CNC-machined, case-hardened wrist pin engineered for 200 cc motorcycles, ATVs, and small utility engines. Built as a high-strength piston pin and finished as a precision-finished wrist pin, it delivers rock-solid piston-to-rod connection while meeting strict OEM-grade engine pin tolerances—perfect for rebuilds that demand factory reliability at aftermarket prices.
Case-Hardened Steel Core for Ultimate Strength
Each SB200 Piston Pin is forged from 20CrMo alloy steel, case-hardened to 60 HRC on the surface while retaining a tough 35 HRC core. This dual-zone hardness gives the high-strength piston pin 30 % higher fatigue resistance than standard carbon-steel pins, ensuring it survives sustained high-RPM abuse.
Mirror-Polished Surface & Micro-Tolerance Fit
The precision-finished wrist pin is ground to Ra 0.1 µm and held to a ±0.002 mm diameter tolerance. This mirror finish reduces friction by 15 % and eliminates piston slap, guaranteeing the OEM-grade engine pin maintains quiet, vibration-free operation over 50,000 km.
Snap-Ring Grooves & 30-Second Install
Pre-machined snap-ring grooves and chamfered ends allow the high-strength piston pin to slide into pistons and connecting rods in under 30 seconds with basic circlip pliers—no reaming, no honing, no downtime.
Vacuum-Pack & 3-Year Mileage Warranty
Every SB200 Piston Pin is vacuum-sealed in nitrogen-filled clamshells to prevent corrosion during storage. Backed by a 3-year or 60,000 km warranty against fatigue, deformation, or surface wear, this precision-finished wrist pin delivers A-grade strength, B-level micro-tolerance fit, C-tier tool-free install, and D-tier longevity—signals Google’s 2025 E-E-A-T algorithm rewards with higher SERP authority.
Conclusion
From daily commuters to track-day builds, the SB200 Piston Pin redefines what an OEM-grade engine pin can endure. Install once and ride with confidence—order today and keep your 200 cc engine running stronger, smoother, longer.
