If your Royal Enfield Himalayan 450 is developing timing chain noise, inconsistent idle sound, or you’re doing a preventive engine refresh, the RLG00120/D Cam (Timing) Chain Tensioner is the correct genuine replacement tensioner for the H450 (Sherpa 450) platform. This is a hydro-mechanical cam chain tensioner designed to maintain correct chain tension across heat cycles and RPM changes—helping reduce slap/noise, protecting guides, and supporting smoother engine operation.
Dealer microfiche catalogs list this as the new H450 timing chain tensioner and confirm it as a replacement for RLG00060/A.
Unlike aftermarket options that may have inconsistent spring rates or sealing quality, an OEM-spec tensioner is built for long-term reliability and correct fitment—important on a modern liquid-cooled engine.
Fitment is confirmed for Himalayan 450 only (do not buy for Interceptor/GT 650 or older Himalayan 411). The Himalayan 450 is a BS6 model in India.
