Kawasaki KX250 Bottom End Gasket Kit - Wiseco - `02-`04. This complete bottom-end kit is built for 2002–2004 KX250 models and combines the crankshaft assembly, main bearings, and a full bottom-end gasket and seal kit in one box to simplify a rebuild.

Wiseco’s bottom-end rebuild kit is intended to save time and reduce parts-sourcing during a dirt bike bottom-end service. The kit includes a precision-machined crankshaft assembly, OEM-quality main and rod bearings, and a complete gasket and seal set to restore the engine’s lower end. The connecting rod is copper-plated, heat-treated, and shot-peened to remove residual stress and improve surface finish. These components are matched and packaged under a single part number for easier ordering and inventory control.
