Product details
Piston Pin (Wrist Pin) — 18mm — Honda CR 250 / KTM SX-EXC 250-380 / Husqvarna TC-TE 250-300
Specifications:
• Outer Diameter: 18mm
• Material: Case-hardened chrome steel — heat treated for maximum durability
• Surface Finish: Mirror-polished to minimize friction and wear
• Fitment: Direct OEM replacement — drop-in fit with no modifications
Engine Compatibility:
• Honda CR 250 (1984-2007): 249cc 2-Stroke — 66.4mm × 72mm bore/stroke
• KTM SX/EXC 250-380 (1996-2021): 249-368cc 2-Stroke — various bore/stroke
• Husqvarna TC/TE 250-300 (1998-2022): 249-293cc 2-Stroke
• Suzuki Quadracer/RM 250 (1985-1998): 249cc 2-Stroke
• Honda ATC-R 250, Odyssey 350, TRX-R 250 (1985-1986)
Function:
The piston pin (also called a wrist pin or gudgeon pin) is the hardened steel shaft that connects the piston to the connecting rod small end. It transfers combustion force from the piston to the connecting rod while allowing the rod to pivot as the crankshaft rotates. A worn, scored, or loose piston pin causes knocking noise, accelerated bore wear, and potential catastrophic engine failure.
When to Replace:
• During any top-end rebuild (piston, rings, cylinder re-bore/re-plate)
• When pin shows visible wear, scoring, discoloration, or blue heat marks
• When pin has measurable play in the connecting rod small end bearing
• Recommended every 2nd piston replacement even if pin appears serviceable
Installation Notes:
• Always replace piston pin circlips — never reuse old circlips
• Apply assembly oil or premix to pin before installation
• Ensure circlips are fully seated in their grooves — improper seating causes engine damage
• Verify connecting rod small end bearing condition before reassembly
• Cross-references across 4 major manufacturers — verify OEM part number match
