Yamaha XJ650 Turbo (Seca Turbo 650)

The Yamaha XJ650 Turbo appeared in 1982. The model was taken as a basis for the Yamaha XJ650R (in the American market it was sold with a prefix in the name - Seca), which received a sporty design with a front fairing and a turbocharger. The new model was available in the North American market (sold under the name - “Yamaha Seca Turbo 650”) and Europe.

However, like other turbocharged Japanese motorcycles of the time, the Yamaha XJ650 Turbo was very expensive and had low sales. In 1983, the motorcycle was featured in one of the James Bond films - "Never Say Never Again".

The Yamaha XJ650 Turbo is based on an in-line 4-cylinder air-oil cooled engine with a volume of 653 cc, producing 90 hp. power and almost 82 Nm of torque. Unlike similar Japanese models with a turbocharged engine, the Yamaha XJ650 Turbo was distinguished by cheaper equipment - in particular, the use of carburetors, instead of electronic injection, a rear drum brake (competitors had disc brakes front and rear) and a double rear shock absorber (similar models from other manufacturers used a more modern monoshock and even progressive swingarms - Honda's Pro-Link and Kawasaki's Uni-Trak). In addition, the motorcycle from Yamaha, compared to competitors, looks more outdated (by modern standards).

Other features of the Yamaha XJ650 Turbo include a steel tubular frame, simple suspension in the form of an air fork at the front and a double shock absorber at the rear, a front disc and rear drum brake, a 15.5 liter fuel tank, a 5-speed gearbox, a cardan drive and 249 kg curb masses.

1983 was the last year of production of the Yamaha XJ650 Turbo, after which it finally left the market and did not receive further development.
