Once again, motorcycles were “behind” cars in terms of adopting this particular technology. Initial attempts to make fuel injectors work on motorcycles were held back by size and weight concerns and by the fact that high performance motorcycle handling is influenced by the rider’s ability to open the throttle and feed in power very smoothly. The first production motorcycle fitted with electronic fuel injection was the 1982 Honda CX500 Turbo. That model was a technological triumph but a commercial failure. As is often the case however, both the CX500 Turbo and its big brother CX650 are now highly collectible.
The Honda's fuel injection system was finicky, and put a lot of people off the idea of injection for bikes. About 10 years later, an even more revolutionary bike, the Yamaha GTS1000 'reintroduced' the idea of fuel injection in a big way. That bike, too, was a commercial failure. It was another decade before EFI systems were really giving carbs the boot.
