Description

The Athena S5F07700002B is a forged piston kit designed for Kawasaki KX250F motocross machines from 2015-2016. It features an advanced forging process for superior strength and resistance to high temperatures and pressures, offering increased engine longevity.

The piston skirt is treated with a Molybdenum Disulfide (MoS2) coating to minimize friction against the cylinder wall. This reduction in friction leads to lower operational heat, reduced wear, a smoother break-in period, and improved overall engine performance with crisper throttle response. The kit includes everything needed for a professional installation.
