1982 Yamaha Seca 650 Turbo

With the appearance of turbocharged Formula One cars in the late 1970s, "turbormania" gripped motorsports and spilled over into everyday life, where the word "turbo" was applied to products from aftershave to vacuum cleaners. In the two wheeled world, every major manufacturer added a turbocharged model. Honda led the way with the CX500T; Yamaha was more cautious.

Struggle for Supremacy

If the turbo represented a low-cost way of boosting the performance of an automobile, the weight and bulk of this bolt-on goody and its attendant plumbing made its advantages less obvious on motorbikes, where large-capacity engines were readily available anyway. But at the time Honda and Yamaha were locked in a bitter struggle for supremacy. The latter couldn't let the former outdo it in terms of high-tech features, even though at the period its finances were under considerable strain.

Keeping Up Appearances

Yamaha chose its XJ650L as a starting point. To speed development while keeping costs as low as possible, the marque decided to retain carburetors rather than shifting to Fuel injection. A small-diameter turbocharger minimized throttle lag. Otherwise, the machine was quite conventional, though its aggressive fairing made it look at least like a fuel-injected 750. However, its performance was little improvement on the normally aspirated version, and sales were low.
