ATHENA YAMAHA 125 YZ 1999-2002 TOP END ECONOMIC GASKET KIT

Athena E4856-116 Top End Reduced Gasket Kit Race Gasket Kit: Athena has specifically designed this RACE GASKET for the Pro, Semi-pro and Amateur riders who freshen up their engine prior to a race series or during mid-season. The kit will include a top of the line MLSS (Multi Layer Stainless Steel) Head Gasket and two premium quality base gaskets, one of which has a reduced thickness of 0.1 mm, to optimize engine compression ratios. This new composition gives the rider/technician a choice to increase compression and decrease the squish in order to get better performances.
