Yamaha Seca Turbo 650 Motorcycle - Street (1981-1983)

The Yamaha Seca Turbo 650, also known as the Yamaha XJ650 Turbo, was a groundbreaking turbocharged motorcycle produced for the 1982 and 1983 model years. While the broader Seca 650 line might span 1981-1983, the turbocharged variant was specifically offered from 1982. It featured an air-cooled, transverse four-cylinder, DOHC engine with a 653 cc displacement, equipped with a Mitsubishi TC03 turbocharger. This setup delivered around 90 HP, making it a powerful machine for its era. Between 1982 and 1983, Yamaha introduced several updates to the Seca Turbo 650. The 1983 model received slightly thicker front forks (37mm vs. 36mm) and an increased fuel tank capacity (19.5 liters vs. 15.75 liters). Crucially, the "Power-Up Kit," which boosted performance, became standard on 1983 models, though it was available as an add-on for 1982 bikes. Minor dashboard changes were also implemented. Engine internals were specifically modified for the turbo version from its inception, including forged pistons and a lowered compression ratio, ensuring durability. FAQ:
