Athena‘s range of Cylinder kits for Off-road and ATV is unmatched in the industry. We offer the largest selection along with completely re-designed porting and water jackets for 2 & 4 strokes to give unparalleled performance gains without sacrificing reliability. All Cylinders are specially treated with nickel-carbide coating, which gives our Cylinders a much longer life. The honing and lapping process performed on each Cylinder ensures greater lubrication of the piston and a better ring seal. Our strict tolerances are maintained using of state-of-the-art CNC machines allowing us to produce the highest quality standards available today. All kits include necessary items for a “bolt-on” installation.
