In 2014, the Yamaha R125 (YZF-R125) model underwent its first restyling, receiving an updated plastic appearance, a new wheel disc design, an exhaust system, a front brake (a 4-piston radial caliper instead of a conventional 2-piston one), a fuel tank (11, 5 liters instead of 13.8 liters), a new front suspension (inverted fork with 41 mm stays instead of the usual 33 mm fork).
