The Ohlins RE506 STX 36 Twin rear shocks are a direct-fit upgrade for the Royal Enfield Shotgun 650, designed to improve chassis control and rear-wheel compliance. Built around Ohlins’ STX twin-shock architecture, they’re intended to deliver consistent damping performance across varied road conditions. This model uses a separated oil/gas damping layout to maintain stable behaviour as temperatures and loads change.
