WÖSSNER Piston Kit for SHERCO SE 125 2017-2023

WÖSSNER offers this piston kit for SHERCO SE 125 2017-2023. The piston slides in the cylinder and takes the force of the air-fuel combustion, passing it to the connecting rod and crankshaft.

Why replace the piston?

The benefits:

• Restore compression, power and easy starting.
• A piston of the right size keeps the intended clearance in the cylinder: less noise and less oil consumption.
• A new piston with rings, pin and clips: nothing to reuse from the old one.

Why choose WÖSSNER?

Wössner has forged its own pistons since 1994: Molykote-coated skirt to reduce friction and ease running-in, kit supplied complete with rings, pin and clips.

When should you replace the piston on your SHERCO SE 125?

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.
