ATHENA offers this cylinder head gasket for YAMAHA WR 250, YZ 250 and KTM EXC 300, MXC 300 1986-2004. The head gasket takes the pressure and heat of every combustion. It is crushed when the head is torqued down and must be replaced every time the head comes off.
The benefits:
Athena, founded in 1973 by Giovanni Mancassola near Vicenza and based in Alonte (Italy), designs gaskets, pistons and cylinder kits; it supplies original equipment to manufacturers such as KTM, Ducati, Fantic and Triumph.
Loss of compression, a dropping coolant level, bubbles in the radiator or traces between cylinder and head: the gasket needs changing. It is also replaced every time the head comes off.
No manufacturer figure in hours for this model. Cross-Mania guideline: compression check every 20 h of hard use and every 40 h of leisure riding.
