1981 - 1983 Yamaha XJ 550
The XJ 550 was launched in 1981. The Yamaha XJ 550 Seca was also well-equipped, with features you’d expect only on bigger, costlier bikes: self-canceling turn signals; a clutch/neutral electrical interlock that prevented the Seca being ridden away with the sidestand down by killing the engine if you shifted into first before lifting the stand.
