Simplicity is considered one of the key selling points of electric motorcycles: twist the throttle and go, without having to worry about gear shifting or clutch operation. Honda is now taking a step in the opposite direction with a new patent, adding exactly this complexity back in. The goal is not an end in itself, but rather more precise control over power delivery, particularly in competition use.

A research team at Otto von Guericke University Magdeburg has developed a hydrogen combustion engine that operates emission-free in a closed cycle and achieved over 60 percent efficiency on the test bench. While the concept is not intended for motorcycles, the technology could influence the two-wheeler industry in the long term.
