VERTEX offers this piston kit for YAMAHA YFM 700 GRIZZLY EPS 4WD, YFM 700 GRIZZLY EPS CAMO 4WD, YFM 700 RAPTOR 2WD 2006-2014. The piston slides in the cylinder and takes the force of the air-fuel combustion, passing it to the connecting rod and crankshaft.

Forged or cast piston?

• Forged: hot-pressed then machined aluminium, stronger when hot and lighter for the same strength; sometimes fitted with a little more clearance, and costs more.
• Cast: aluminium poured into a mould, like most OEM pistons; it expands little, runs quietly and costs less, but tolerates overheating less well.
• In short: forged for racing or a tuned engine, cast for a stock engine used for leisure riding.

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 four-stroke pistons are forged from 2618 alloy.
