The Royal Enfield 148503/C Bearing Sleeve, Swingarm is a genuine OEM component used in the rear swingarm assembly of compatible Royal Enfield motorcycles.
This sleeve works with the swingarm bearing and associated pivot components to provide proper support and smooth movement of the rear swingarm. It is an important component of the swingarm pivot assembly and should be inspected for wear whenever the swingarm bearings are serviced.
Royal Enfield parts catalogues identify 148503/C as “BEARING SLEEVE, SWINGARM” and list it in the rear suspension assembly of the Continental GT 650 and Interceptor 650.
