Overview

The ProX Connecting Rod Kit for the KTM 250 SX (2000-2002) is a comprehensive bottom-end rebuild solution designed to restore engine performance to factory specifications. The connecting rod is double forged, shot peened, and barreled — a multi-step manufacturing process that increases material density, relieves surface stress, and improves fatigue life under the demanding conditions of a high-revving two-stroke engine. Precisely located oiling slots are machined into the rod to ensure consistent lubrication delivery to the big-end and small-end bearings during operation.

Each kit ships with all the hardware required for installation: a crankpin, big-end bearing, small-end bearing, and thrust washers. This all-in-one approach simplifies the parts-sourcing process and ensures that all components are matched for proper clearance and fit. The kit is engineered for direct OEM drop-in replacement, meaning the rod dimensions, bearing sizes, and crankpin specifications match the original KTM parts without requiring any machining or modification to the crankcase halves.
