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 sizes.
ATHENA offers this piston kit for SUZUKI RM 250 2000-2002. 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 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 SUZUKI RM 250?
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.
