Yamaha Seca 400 Motorcycle - Street (1982-1983)

The Yamaha Seca 400, offered from 1982 to 1983, was a sport motorcycle available in two distinct versions: the XJ 400 Seca and the XS 400R Seca. The XJ 400 Seca, primarily sold outside North America, was equipped with a 398 cc transverse four-cylinder engine producing 45 hp. The XS 400R Seca, aimed at the North American market, featured a 399 cc parallel twin engine generating 45.5 hp. These models were characterized by their sporty styling. Between 1982 and 1983, the XJ 400 Seca saw no significant engine or generational changes. For the XS 400R Seca, while the 1982 model introduced major upgrades over earlier versions (new DOHC engine, monoshock rear suspension), no further significant engine or platform changes were reported specifically between the 1982 and 1983 model years. The "RJ" and "RK" designations for the XS 400R Seca primarily denote the model year. FAQ:
