16X43 gudgeon PIN VERTEX

VERTEX 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 VERTEX?

Vertex has made its pistons in Italy since 1953 and has supplied KTM’s original pistons since 1996: molybdenum-disulphide coated skirt and Japanese rings. Its two-stroke pistons are cast from an 18 % silicon alloy. Its four-stroke pistons are forged from 2618 alloy.

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.
