High-quality connecting rod kit designed as a replacement for the Honda CR125R (1988–2007). Manufactured from hot-rolled ASTM 4115 steel and case-hardened to 58–62 Rc for exceptional durability. The advanced design includes side scalloping and vent slots to reduce high-rpm bearing race distortion. Double-forged construction enhances grain flow and dimensional consistency, while shot peening and double-honing increase strength under heavy loads.

The small ends are double-drilled to improve lubrication and cooling for the wrist pin bearing, a critical feature for pistons with crowns close to the wrist pin. Thrust washers and crank pin bearings are silver-coated to enhance lubricity. Kits include all necessary components: rod, crank pin, crank pin bearing, top-end bearing, and thrust washers.
