Rear Wheel Shaft 54P-E7421-00 For Yamaha Ego S Egos Fi Mio J
Restore smooth rear wheel alignment and reliable drive transfer with this direct-fit Rear Wheel Shaft (OE 54P-E7421-00) engineered for specific Yamaha scooter models. A worn, bent, or cracked rear axis creates side-to-side wobble, erratic chain tension, and accelerated sprocket damage. Installing this original-equipment replacement returns the drive train to precise centerline alignment, eliminating binding and ensuring consistent power delivery from the variator to the road.
Machined from hardened steel and finished to factory tolerances, this shaft mounts directly into the gearbox and swingarm without machining or modifications. It provides a corrosion-resistant mounting point for the rear hub and transmission bearings, making it an essential fix for grinding noises, uneven tire wear, or failed axle assemblies after routine maintenance.
Benefits & Tips
- Align the internal splines fully before pushing the shaft through to prevent gear tooth damage.
- Lightly lubricate bearing mating surfaces with high-temp greasing compound for smoother initial rotation.
- Inspect the drive belt and CV rollers while the rear wheel is removed to maximize long-term reliability.
