Product details :

Features

The ATHENA cast piston is designed for 2-stroke engines intended for off-road use. Made from aluminum, it offers a finish and tolerances suitable for the demands of motocross: repeated starts, high RPMs, and demanding operation. This standard piston maintains the manufacturer's specifications while providing the necessary precision to achieve good sealing and consistent engine behavior after refurbishment.

Type: cast piston
Brand: ATHENA
Diameter: Ø 57.95 mm (57.950 mm)
Oversize: +0.01 mm — letter B
Compression: standard
Material: aluminum
Manufacturer reference: S4C05800001B

Ideal for preparations and replacements during a light re-bore (+0.01 mm), this piston fits into blocks intended for motocross and adapts to original settings. It is particularly suitable for the YAMAHA models listed as compatible (TT‑R 125 LW Big Wheels E 2021, YZ 125 2020 and 2005). For a secure installation, check the piston/ring clearances and follow the manufacturer's recommendations for re-boring and running-in. ATHENA remains a reliable choice for those seeking a quality wear part for their off-road engine.
