The engine is fed by **six individual 28mm Keihin carburetors**, requiring intense synchronization. The **alternator** was moved *behind* the engine to keep the massive block as narrow as possible.

Performance Benchmarks

The CBX was significantly heavier and more powerful than its four-cylinder counterparts, positioning it as a truly dominant machine in the late 70s.

Power-to-Weight:

While the CBX had far more raw power, its unique engine width and mass resulted in a higher curb weight than other high-performance Honda Fours.
