HONDA CRF 250
CYLINDER, PISTON, GASKET KIT
Ø 76,8 mm / 249,2 cc
ATHENA presents its new Kit for the HONDA CRF 250, tested on tracks and on dynamometric bench. ATHENA produces this cylinder
in a BOLT-ON version, in other words it can be installed on the engine without any crankcase modifications. ATHENA have matched
the cylinder with a forged piston which is lighter than the OE, we intended to reach the best performances ever. The gaskets have
been developed using last generation technologies; in particular the multilayers head gasket provides a new system of reliefs that
guarantees a perfect seal even at high temperatures.

1. Projects use 3D Solid Modelling software creating
virtual simulation and verification of mechanical
2.Aluminium cylinder cast in steel moulds and manufactured by CNC machines to assure millesimal
tolerances during all manufacturing phases.
3.Redesigned water jackets to increase capacity
4. Cylinder liner with a special silicon carbide and nickel coating mixture to grant the best fluidity of the
piston and durability of the cylinder.
5.Lapping performed in rooms with indoor temperatures of around 20 degrees, in order to have an
excellent control of the boring and of each cylinder
6. Cylinder support surfaces are perfectly parallels in
order to eliminate any matching inaccuracy.
