Motorcycle specifications YamahaYZ 125 2015 For tomorrow's pros

for 2015, major improvements have been made to Yamaha's YZ 125 to boost on-track performance. In addition to technical improvements, this model boasts dynamic styling and a deco kit reminiscent of the modern styling of the latest four-stroke models.

The low weight and rapid rev-up of the 2-stroke 125 cm3 engine make the YZ 125 the ideal competition bike for teenagers who want to make a name for themselves. Alongside the YZ 85 and YZ 250 2-stroke models and the YZ-F 4-stroke models, the YZ 125 is an integral part of Yamaha's competition range. It is primarily aimed at young riders, for whom the 125 2T offers one of the best ways of perfecting their skills before moving up to the next category aboard a YZ 250 F or YZ 450 F.

After winning several rounds and finishing in 2nd position overall in the EMX 125 European Championship, the current YZ 125 is once again performing exceptionally well in the 2014 championship, ridden by Frenchman David Herbreteau. At the end of the first four rounds (out of seven) of this highly competitive championship, Yamaha found itself among the top three bikes, proving that the YZ 125 can rank at the top of one of the world's most prestigious 2T races.

The 2015 YZ 125 2T model has undergone radical styling changes to create a sleek, modern silhouette. At the same time, significant technical improvements offer enhanced handling.

The redesigned bodywork and new graphics project an image of elegance and lightness similar to that of the new-generation YZ-F 4T. New front and rear mudguards, number plate, radiator gills, air box, side covers, fork protectors and seat cover make it look like a state-of-the-art factory motorcycle. In addition, bold Speed Block graphics, a large YZ logo on the tank and radiator fins emphasize the horizontal line launched on the latest YZs.

For 2015, significant changes have been made to the front and rear suspensions, which have already been used on the new YZ-F 4Ts. The 48mm inverted front fork and Monocross rear suspension feature YZ 125-specific settings for excellent traction and grip. Front and rear suspension can be fully adapted to suit track conditions, rider weight and riding style.

for quick and easy adjustment, the 2015 model is equipped with a clutch free travel adjustment knob identical to the YZ-F 4T. In addition, the YZ 125 features wide YZ-F-type footrests for enhanced comfort and feel, especially for jumps and whoops. Final touches to the 2015 model: the latest Dunlop tires, rear crown, rear disc protector and YZ-F-style rear caliper protector.
