The Yamaha XJ 750 Seca was a motorcycle made by Yamaha in 1982, based on the technology used on the sportier XJ 650 model. The bike was named after Laguna Seca Raceway, a Californian racetrack near Monterey, California.
Compared to the sportier XJ 650 model, the XJ 750 Seca was more like a chopper. The bike had an onboard computer that constantly monitored essential functions, such as side stand position, brake fluid, oil level, battery fluid, headlights, and brake lights.
In Germany, the manufacturer sold 3,181 units at an MSRP of $8,000, and in 1984, it was replaced by the Yamaha XJ 750 F.
In 1981, the Japanese motorcycle manufacturer launched the Yamaha XJ 750 Seca, a chopper-oriented motorcycle with the most technically advanced package.
In the visual department, the bike had standard features, such as a rectangular headlight with a smaller beneath, a one-piece dual seat with a passenger grab handle, a four-into-two exhaust system with a silencer on each side, and five double-spoke lightweight wheels.
The bike was built around a double-cradle steel frame with a telescopic fork on the front, offering 150 mm of travel, and side-mounted shock absorbers on the rear, providing 96 mm wheel travel.
As for the power figures, the 1981 Yamaha XJ 750 Seca had its soul brought to life by a 749cc four-stroke air-cooled four-cylinder engine that delivered an output power of 76 hp at 9,000 rpm and 66 Nm (49 lb-ft) torque at 7,500 rpm.
