The piston moves up and down in the cylinder to turn combustion into motion: this kit replaces it along with its rings, pin and clips.
PROX offers this piston kit for YAMAHA YZ 80 1993-2001. The piston slides in the cylinder and takes the force of the air-fuel combustion, passing it to the connecting rod and crankshaft.
Why choose a cast piston?
A cast piston is made by pouring liquid aluminium into a mould: it is what most manufacturers fit as standard, especially on two-strokes.
- High-silicon alloy: it expands little, is fitted with tight clearance and stays quiet when cold.
- Good wear resistance of the skirt and ring grooves.
- Lower price than a forged piston, for OEM quality in normal use.
- Limit: less tolerant of overheating and highly tuned engines.
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 the piston on your YAMAHA YZ 80?
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 15 h in hard use and every 30 h for leisure.
