For 2015, significant improvements have been made to the Yamaha YZ 125 to boost performance on the track. In addition to technical improvements, this model sports a dynamic look and a graphic kit which are reminiscent of the modern style of the latest four-stroke models..
The low weight and rapid revving of the 125cc 2T engine make the YZ 125 the ideal competition bike for teenagers who want to make a name for themselves. In addition to the YZ 85 and YZ 250 2T models and the YZ-F 4T models, the YZ 125 is an integral part of the Yamaha competition range. It is mainly intended for young pilots, for whom the 125 2T offers one of the best means to improve before moving to the next category on the handlebars of a YZ 250 F or a YZ 450 F..
After winning several rounds and finishing in 2nd position in the general classification of the EMX 125 European Championship, the current YZ 125 is once again showing exceptional performances in the 2014 championship, driven by Frenchman David Herbreteau. At the end of the first four rounds (of seven) of this highly competitive championship, Yamaha finds itself among the top three motorcycles, proving that the YZ 125 can place at the top of one of the most prestigious 2T races in the world..
The 2015 YZ 125 2T model has undergone radical stylistic changes aimed at creating a slender and modern silhouette. In addition, significant technical improvements offer increased maneuverability.
The redesigned bodywork and new graphics project an image of elegance and lightness similar to that of the new generation of YZ-F 4T. The new front and rear fenders, number plate, radiator gills, airbox, side covers, fork guards and seat cover make it akin to a state-of-the-art factory motorcycle. In addition, bold Speed Block graphics, the large YZ logo affixed to the tank and radiator gills highlight the horizontal line launched on the latest YZs..
For 2015, significant changes were made to the front and rear suspensions, these suspensions having already been used on the new YZ-F 4Ts. The 48mm inverted front fork and Monocross rear suspension feature YZ 125-specific settings to ensure excellent traction and optimum grip. Front and rear suspensions can be fully adapted to track conditions, rider weight and riding style.
For quick and easy adjustment, the 2015 model is equipped with a clutch free-play adjustment dial identical to the YZ-F 4T. In addition, the YZ 125 has large YZ-F type footrests for increased comfort and feel, especially for jumps and whoops.
