The Royal Enfield 148331/A Fork Main Spring is a genuine OEM front suspension component designed for the Royal Enfield Interceptor 650 and Continental GT 650.
The main fork spring is installed inside the front telescopic fork and plays an important role in supporting the motorcycle’s front end, maintaining ride height and absorbing bumps and road impacts. It works together with the fork spacer, damper tube and top-out spring as part of the complete front fork assembly.
Royal Enfield parts listings identify 148331/A with the exact catalogue description “FORK, MAIN SPRING.” The part is listed for the 650 Twin front fork assembly, while OE listings specifically confirm compatibility with the Interceptor 650 and Continental GT 650.
