Description
The connecting rod is the mechanical heart of your Yamaha RX100, converting explosive 2-stroke power into rotational motion. Over decades of high-RPM screams, original rods can develop “big-end” play, leading to catastrophic engine vibration and power loss. The TKRJ Connecting Rod Kit is engineered in Japan to OEM+ standards, providing the surgical precision required to bring your crankshaft back to factory-perfect balance.
Why TKRJ is the Gold Standard for RX100 Crank Rebuilds:
Japanese Forging Excellence: Unlike cheap aftermarket rods, TKRJ units are forged from high-tensile steel to handle the intense reciprocating loads of a high-revving 2-stroke engine without flexing or snapping.
Precision-Honed Big-End: The big-end bore is machined to micron-level tolerances, ensuring a perfect oil film clearance for the needle bearings, which prevents overheating and “seizing” at high speeds.
High-Load Needle Bearings: The kit includes a premium Japanese big-end bearing designed to withstand the high-frequency hammering of 2-stroke combustion, ensuring your crank remains whisper-quiet.
Optimized Oil Flow: Features specialized lubrication slots and holes designed to catch 2-stroke oil mist and direct it straight to the crank pin, extending the life of your bottom end significantly.
Perfect Weight Matching: Engineered to the exact weight specifications of the original RX100 rod, maintaining the engine’s internal balance and reducing the “numbness” in your handlebars at high RPMs.
