KTM LC4 / DUKE 400 / 620 / 640 1994 - 2007 PROX CON ROD

Premium ProX Connecting Rod Kit

Restore your engine performance and reliability with the ProX Connecting Rod Kit. Engineered to meet or exceed strict OEM specifications, this kit serves as a high-quality, cost-efficient replacement for your worn internal components. Manufactured by leading Japanese OEM factories, ProX ensures that every rod kit provides the durability required for demanding engine environments.

Advanced Forging and Surface Engineering

ProX utilizes a double-forging process on dedicated forgings to maintain superior strength and dimensional consistency. By improving grain flow during production, the connecting rod achieves excellent structural integrity. Each rod undergoes precision shot peening and barrelling, processes that remove residual stress and create a smooth, durable surface texture to withstand high-stress operation.

Optimized Lubrication and Longevity

Reliable oil flow is critical for engine lifespan. The ProX connecting rods feature precision-located oiling slots designed to maximize lower rod lubrication. By ensuring consistent oil delivery to the big-end bearing, these kits help extend the service life of your crankshaft assembly even under extreme riding conditions.
