This radical, high-revving, fuel-injected 125 is the work of the same engineers who created our legendary YZF-R1 and YZF-R6 supersport bikes. And, as you’d expect, the YZF-R125 is packed with advanced MotoGP technology as well as a whole range of R-series type engine and chassis features. Its liquid-cooled, 4-stroke, 4-valve, single cylinder, SOHC engine is tuned to deliver free-revving performance right through to maximum power at 9000rpm – and for instant response and efficient operation this remarkable 6-speed 125 is equipped with a compact fuel injection system. For instant throttle response, this new high-tech 125 features a compact fuel injection system fed by a large-capacity airbox which, combined with the two inlet valves, delivers optimum intake efficiency together with excellent throttle response across the rev range.

Performance is also enhanced by the fitment of a free-flowing largecapacity R6-style mid-ship muffler, whose location helps to centralise mass for neutral handling performance. To optimise the class-leading performance characteristics of its all-new high-tech 125cc liquid-cooled engine, the R125 is equipped with a 6-speed transmission which keeps the engine on the boil and ensures a competitive top speed.
