PROX 16X45 non-chromed gudgeon pins

PROX 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 PROX?

ProX has its pistons made in Japan and the USA, with Japanese rings (Riken, TP or NPR) and tolerances at least equal to OEM; most of its four-stroke pistons are forged.

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.
