The NTN bearing 6303-2RS (manufacturer reference 6303LLU/5K) is a spare part designed for the running gear of motorcycles and quads. Its compact dimensions of 17 x 47 x 14 mm make it a common choice for hubs, pivots, and bearings subjected to urban and off-road use.
The 2RS version limits the entry of water and dust thanks to its sealing rings, which is useful on wet roads, in urban environments, or for off-road use (cross, quad). Suitable for maintenance interventions on the hub or for replacement in case of bearing noise or excessive play, this bearing fits many wheel/pivot assemblies.
Common applications: urban, roadster, quad, cross. Suitable for several popular models — for example, motorcycles like the HONDA CBR 500 R, KAWASAKI W 800 STREET, or TRIUMPH SCRAMBLER 865 — provided that you check the dimensions and compatibility with your machine. A useful part to restore the running gear and get back on the road with confidence.
