Wössner Forged Piston for KAWASAKI KLX 450, KXF 450 2006-2019

WOSSNER offers this piston kit for KAWASAKI KLX 450, KXF 450 2006-2019. 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 forged piston?

Instead of simply being cast, a forged piston is hot-pressed under very high pressure and then machined: its metal is denser and free of air pockets.

• Stronger when hot: it copes better with high revs, overheating and detonation.
• Lighter for the same strength: less stress on the connecting rod and bearings.
• Good to know: depending on the alloy, it expands a little more and is fitted with more clearance; slight noise when cold is normal.
• Why does it cost more? Forging tools, full machining and surface treatments cost more than simple casting.

Why choose WOSSNER?

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 KAWASAKI KLX 450?

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

Recommended hours for a top-end rebuild (manufacturer recommendation for the Kawasaki KX 250 F / KX 450 F (four-stroke)):

• Racing: every 15 h (about 6 races).
• Leisure: no Kawasaki figure; Cross-Mania guideline: compression check at around 30 h.
