Typical Use Cases
- Replacement for a damaged, cracked or worn original rear wheel hub on Z300-based motorcycles.
- Base component for building a complete spare 18-inch rear wheel (for example, with an alternative tyre for different terrain conditions).
- Restoration of correct wheel alignment and bearing preload when the original hub has excessive play or out-of-round bearing seats.
- Use in performance-focused enduro and off-road riding where consistent spoke tension and hub rigidity are important.
Component Integration
This hub assembly is designed to work together with the dedicated rear wheel hardware used on the Z300 platform, including the original rear axle, axle nut, rear wheel bushings, chain adjusters, hub bearings (type 6005) and hub oil seals (32x47x7 mm). When assembled with these matching components, it forms the core of the complete 2.15x18 rear wheel suitable for enduro and cross-country riding.
