PRESSOL piston kit

PRESSOL offers this piston kit. 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 PRESSOL?

PRESSOL is a German maker of lubrication and fluid-transfer equipment.

When should you replace the piston?

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