The Wössner 8952DA piston is particularly suitable for Honda CRF 250 R (ME12) models from 2018 and 2019. Its machining and forged design provide better mechanical strength and superior fatigue resistance compared to cast pistons, without guaranteeing a specific power gain — these parameters depend on the overall assembly and engine settings. Before installation, check the condition of the cylinder, the clearances, and adhere to the manufacturer's recommendations for the pin and rings.
