ATHENA Cast Piston for SHERCO SE 300 2016-2025

ATHENA offers this piston kit for SHERCO SE 300 2016-2025. The piston slides in the cylinder and takes the force of the air-fuel combustion, passing it to the connecting rod and crankshaft.

Why a cast piston?

A cast piston is moulded from a high-silicon aluminium alloy, then machined.

• Low expansion: it runs with a tight clearance, stays quiet when cold and warms up quickly.
• Durability: an excellent choice for a stock engine used for leisure or enduro.
• Price: more affordable than a forged piston.
• Good to know: it copes less well with overheating and extreme revs than a forged one.

Why choose ATHENA?

Athena, the Italian manufacturer founded in 1973, is an original-equipment supplier to manufacturers such as KTM and Ducati: the same standards for your replacement parts.

When should you replace the piston on your SHERCO SE 300?

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 20 h in hard use and every 40 h for leisure.
