The SE was the dressed-up Bonneville of the 865 cc fuel-injected era, adding a rev counter alongside the speedometer, polished engine covers, a chrome tank badge and optional two-tone paint with hand-painted pinstripes. Styling stayed retro with short mudguards and upswept megaphone silencers, while mechanicals matched the standard bike.
