We're way off. Make it 1982: I was clsoe though, 98 VFR was the 2nd bike to get it !
History of Honda's PGM-FI development for motorcycles
Honda started more than 20 years ago to develope a FI system to constantly provide the optimum air fuel ratio required by the engine using electronic control techniques. Since then, Honda has been actively promoting the application of FI to motorcycles as a technique to realize environmental performance and high level driveability.
In 1982, Honda marketed the first-in-the-world, fuel injected motorcycle CX500TURBO, which attained both better acceleration performance than the CB900F and better fuel economy than the base model CX500. In 1998, the environmentally friendly sport tourer model VFR800FI was marketed. This model, using the PGM-FI and the newly developed three-way catalyst, attains 1/30 CO emissions and 1/10 HC+NOx emissions from the EURO1, which is the European exhaust emission regulation enacted in 1999. And now, the racing machine "RC211V" has been dominating the MotoGP races. The "RC211V" uses the PGM-FI, which aids in allowing the overwhelming power output of the RC211V to be controlled for efficient use by the rider. Honda always keeps improving the fuel injection system at the highest level of technical competition.
The first motorcycle equipped with an electronic fuel injection - CX500TURBO
In the late 1970's, Honda R&D was filled with enthusiasm towards attaining "core technologies that would lead to the development of new technologies in the 1980's". Through discussions on what should be the core technologies, "turbo charging" was choosen, and the CX500 was selected as the base model. Honda defined the purpose of "turbo charging" not merely as a boost of extra power output from a large displacement engine, but an increase of specific power from a small displacement engine, and an increase in thermal efficiency by reducing the frictional losses per output. Simply stated, it was to attain both an increase in power output and a reduction in energy loss. Most critical in the development were the turbo charger and the fuel injection control systems. The CX500TURBO eventually made the first step of innovation into the 1980's with its acceleration performance better than the "CB900F" and fuel economy better than the base model "CX500".
Computer controlled fuel injection
One of the features of the CX500TURBO was the practical application of the computer controlled fuel injection system. Instead of using the then-conventional air flow meter, the computer-controlled fuel injection system calculated the injection volume using the two control maps, i.e., one for the boost zone where the basic injection volume was determined by the engine revolutions and the boost pressure, and the other for the throttle zone where the basic injection volume was determined by the engine revolutions and the throttle opening. The actual injection volume was adjusted by the intake density compensation, the intake air pressure and/or intake air temperatures, the supplement for acceleration, warming up, starting, the compensation for battery voltage, etc. Also incorporated in the computer-controlled fuel injection system was a self-diagnosis system that activated the warning lamp and the backup system to keep the engine running when a failure occurred in the system.
