YZF-R125 - Inspired by genius

The YZF-R125 is the most advanced 125 production supersport machine that Yamaha has ever built. 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 9,000rpm and for instant response and efficient operation this remarkable 6-speed 125 is equipped with a compact fuel injection system. The race-inspiredchassis features a Deltabox 

 frame and aluminium swinging arm for outstanding handling performance, and lightweight 5-spoke wheels help to minimize unsprung weight to give impressive roadholding. A large diameter 292mm front disc with a 230mm diameter rear disc make for effective stopping power, and the aggressive R-series bodywork lets everybody know exactly where this bike’s DNA has come from!
