Inline-four engine

Usage in motorcycles

Inline-four engines are also used in MotoGP by the Suzuki (since 2015) and Yamaha (since 2002) teams. In 2010, when the four-stroke Moto2 class was introduced, the engines for the class were a 600 cc (36.6 cu in) inline-four engine made by Honda based on the CBR600RR with a maximum power output of 110 kW (150 hp). Starting in 2019, the engines were replaced by a Triumph 765 cc (46.7 cu in) triple engine.
