Product Overview
This high-quality Aftermarket Crankshaft Assy (13000-KZR-601) is designed to meet or exceed factory performance standards and is suitable for Honda PCX 125 (2013–2020) models.
The crankshaft assembly converts the up-and-down motion of the piston into rotational power that drives the engine and transmission system. Operating under constant load and high engine speeds, the crankshaft plays a critical role in maintaining smooth engine balance, stable power delivery, and reliable overall performance. Over time, bearing wear, poor lubrication, overheating, or internal engine damage can cause excessive vibration, knocking noises, rough running, reduced engine performance, and serious bottom-end engine failure. This aftermarket replacement is engineered for fit and function, restoring smooth engine rotation, proper crank balance, and dependable everyday performance for your Honda PCX 125.

Complete Part Guide
The crankshaft is the fundamental rotating heart of the 2013-2020 Honda PCX125 engine, converting piston movement into the driving force that rotates your rear wheel. A failed big-end bearing or snapped crank pin results in catastrophic engine locking and a total loss of power. This trade-grade, Honda aftermarket replacement part (13000-KZR-601) provides the structural integrity needed for demanding London driving. Physically stocked at Part Hive’s London warehouse; we provide same-day UK dispatch on orders confirmed before 1 PM.
One of the most worrying noises we encounter on 2013–2020 Honda PCX-125s is a deep knock from the bottom end. We often trace this to oil starvation or “crank‑slap” after 40,000+ miles of heavy filtering. Once the big‑end bearing develops play, vibration spreads quickly, destroying main bearings and oil seals. This performance‑grade, Honda aftermarket Crankshaft Assy (13000-KZR-601) is built to exacting standards for durability and balance to ensure smooth, rattle‑free rotation. Unlike low‑quality, unbalanced cranks that fatigue the crankcase, this heavy-duty assembly restores stability and protects the engine from premature wear, giving riders back dependable performance for long‑term commuting.
