WISECO Gudgeon Pin 16 x 52.1 mm

WISECO offers this piston pin. The pin passes through the piston and the small end; it is held by two clips. A marked or worn pin creates play and noise.

Why replace it?

The benefits:

• Remove play or noise at the piston.
• A precise replacement part without buying a whole piston.

Why choose WISECO?

Wiseco has forged its pistons in Mentor (Ohio, USA) since 1941 and controls the whole process, from aluminium bar to the friction-reducing ArmorGlide skirt coating. Its pistons are developed with Team Honda HRC in Supercross (450 class since 2018).

When should you replace this part?

Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.

No manufacturer hour figure for this model. Cross-Mania guideline: compression check every 30 h in hard use and every 60 h for leisure.
