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. Available in several bores.
VINTCO offers this piston kit for MAICO GS 400, MC 400 from 1974 to 1981. 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 VINTCO?
Vintco, the American vintage-bike specialist since the early 1990s, remanufactures engine parts to the original standard, with the OEM part numbers listed.
When should you replace the piston on your MAICO MC 400?
Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.
