Important Fitment Check
Before ordering, compare the original hub casting, brake-panel shape, spoke-hole count and angle, sprocket-side arrangement, axle and bearing sizes, brake-arm position and brake-panel locating features. Honda used different rear wheel assemblies across markets and later model years.
This listing is for the hub and brake-plate assembly only. A wheel rim, spokes, rear sprocket, axle, chain adjusters and other wheel hardware are not included unless they are visibly shown with this exact product.
Installation & Safety
Rear wheel and brake parts are safety-critical. Correct spoke lacing, wheel truing, bearing seating, brake-shoe alignment and brake adjustment are essential. Check the brake drum surface and confirm the wheel runs true after assembly. Professional wheel building and brake inspection are recommended.
