The piston moves up and down in the cylinder to turn combustion into motion: this kit replaces it along with its rings, pin and clips.
WOSSNER offers this piston kit for HONDA TRX 400 FA FOURTRAX RANCHER AUTO 4WD, TRX 400 FW FOURTRAX FOREMAN 4WD 1996-2005. 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 HONDA TRX 400 FW FOURTRAX FOREMAN 4WD?
