Two types of CBS, Combi Brake (Single CBS) and dual CBS Honda’s CBS can be largely classified into two types; Combi brake adopted for scooters, medium sized motorcycles and American custom models and dual CBS used by large sports and large tourers. The main purpose of the two types is the same; to increase the deceleration obtained on appllication of […]

Dual CBS for large sports tourers Honda has further advanced Combi Brake, which will work simultaneously on the front and rear wheels by operation of the pedal (left lever) only, to develop dual CBS for application to much larger sports models. Based on the front double disk brake and rear disk brake, this not only brakes the front and rear […]

Two types of combined ABS combining CBS and ABS Honda is now using two types of ABS for motorcycles, ABS using circulating type modulator widely used in automobiles and ABS used exclusively by motorcycles with modulators driven directly by motors. There are cases of using those two types of ABS as they are for the conventional brake system and of […]

Merits of Combined ABS Advanced brake systems developed by Honda so far, CBS and ABS, were merged as combined ABS to enable to produce a greater effect. The figure below shows a comparison of maximum deceleration generated by operation of the pedal alone in a model between the conventional brake and the advanced brake systems. The deceleration generated by the […]

Development of the ECU-integrated throttle body module To allow for application to a small motorcycle, the FI system had to be simplified and down-sized considerably from the conventional one. The development team packed various functions into the compact yet simple system that could be installed in the place of a conventional carburetor by modularizing the throttle body, various sensors, and […]

Advantages of newly developed compact PGM-FI In 1992, Honda addressed to the world the “Honda Environment Declaration”, in that declaring “Actively be involved in the retention of personal health and preservation of global environment, and maintain advanced characteristics in such activities.” The PGM-FI technology is aimed at improvement of practical fuel economy, driveability, etc. to a high level as well […]

PGM-FI for 4-stroke 50cc scooters We would like to actively introduce environmental technology into the vehicles being used by many people. By so doing, we wish to contribute to the improvement of the global environment even if a little. Here is the basic stance of Honda for environmental technologies including fuel consumption and cleaner exhaust gas. Asaka R&D Center evolved […]

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.

PGM-FI Electronic Fuel Injection To attain clean exhaust gases and high fuel economy, an electronic fuel injection system that permits accurate control of the air-fuel ratio should be applied. The development team at Honda R&D Center consolidated the functions into the size of a conventional carburetor through the ultimate modularization of components, thus developing the ECU-integrated throttle body for an […]

The newly developed PGM-FI (electronic fuel injection) system for small motorcycles The development of an ECU-integrated throttle body module for an electronic fuel injection system for small motorcycles Honda has a goal to reduce the total emissions of HC (hydro-carbon) from new vehicles to approximately 1/3 and to further improve the average fuel economy by approximately 30% (both from 1995) […]
