CONNECTING ROD KTM 125-144-150, HOTRODS 8670, 50330015100

Hot Rods Connecting Rod Kit for KTM 125-144-150

Enhance the performance and durability of your motorcycle with this high-quality connecting rod kit from Hot Rods. Engineered for demanding use, this kit is constructed from premium materials and features advanced design elements to ensure optimal operation and longevity.

The connecting rod is crafted from hot-rolled ASTM 4115 steel, which is then case-hardened to a hardness of 58-62 Rc. This treatment significantly increases wear resistance and overall strength. Advanced scalloping and vent slots are incorporated into the big end design. These features are specifically engineered to minimize bearing race distortion, even at high revolutions per minute (RPMs), ensuring consistent performance under stress.

Further enhancing the rod's structural integrity, the double-forged construction improves the material's grain flow, contributing to greater dimensional consistency and preventing potential weaknesses. The rod undergoes a shot-peening and double-honing process. Shot-peening introduces compressive residual stresses to the surface, increasing fatigue strength, while double-honing ensures precise surface geometry for optimal bearing performance and durability under heavy loads.

The small end of the connecting rod features double-drilled ports. This design optimizes the flow of lubrication and cooling to the wrist pin bearings, guaranteeing reliable operation and extended lifespan for these critical components, even in extreme operating conditions.

To further enhance lubricity and longevity, the kit includes silver-coated thrust washers and crank pin bearings. These premium components provide an extra layer of protection and smooth operation.

This comprehensive kit is sold complete with all necessary components for a straightforward installation, ensuring you have everything needed for a successful replacement or upgrade.
