KTM tested its new 850cc engine for the MotoGP era starting in 2027 on the race track in Jerez for the first time. The first laps mark an important step toward the upcoming regulations, which will bring about profound technical changes.

General Motors is working on a novel two-stroke concept designed to avoid the classic weaknesses of this type of engine. A recently published patent application shows how an electronically controlled valve system could reduce emissions and improve efficiency and durability.
