Featuring a liquid-cooled single-cylinder engine running in full-sized Deltabox chassis – and clothed in aggressive R-series style bodywork – the YZF-R125 is aimed at the young first-time 125 buyer, and sporty lovers who wants good look and performances.
In order to achieve this goal, Yamaha’s engineers have created the company’s first ever liquid-cooled 4-stroke single-cylinder 125cc SOHC engine. The new R125 benefits from a 4-valve cylinder head.
This new high-tech 125 features a compact fuel injection system fed by a large-capacity airbox.
Featuring bore and stroke dimensions of 52mm x 58.6mm, the compact short-stroke engine has a free-revving character. It would be a high rev lover...
The R6-like silencer is not only here for the look. The exhaust system accommodates dual catalysers, as well as an air induction system which introduces air into the exhaust to enable more complete combustion of any unburnt gases, and in doing so it helps to reduce emissions to even lower levels.
To optimise the performance characteristics of its all-new high-tech 125cc liquid-cooled engine, the R125 is equipped with a 6-speed transmission which ensures strong acceleration and a competitive top speed.

CHASSIS
Just like its larger R-series brothers, the new R125 features a Deltabox frame.
One of the most significant features of the new R125 is that it has been constructed with a full-sized chassis, which is unique in its segment. For example, the wheelbase on the new Yamaha R-series is 1,353mm, over 58mm greater than a typical sports 125.
The R125 stands out in the crowd, and is easy to mistake for a much larger capacity machine (young riders must love that!). The dual headlights have a distinctive R-series look, while the low frontal area and small tail are clearly influenced by the bigger R-series bikes.
Complementing the race-bred Deltabox frame is a cast aluminium swinging arm. By keeping unsprung weight low, this high quality swinging arm allows the link-type rear suspension system to operate more efficiently.
Equipped with large-diameter 33mm tubes, the smooth-action front forks are designed to deliver accurate steering together with good rider comfort. For easy manoeuvrability this high quality front suspension system features a steering angle of 24.2degrees and trail of 86.1mm. And with 130mm of wheel travel.
The front braking system is a large diameter 292mm front disc slowed by a compact twin-pot caliper. The large single front disc is complemented by a 230mm rear disc.
The new YZF-R 125 is fitted with new light spoked wheels and some of the widest rubber in the class, with a 100/80-17 tyre at the front, and a massive 130/70-17 tyre at the rear.
Yamaha have developed a range of accessories for YZF-R125 owners wishing to customise their bike. The line-up includes a double bubble screen, a yoke, a seat cover, roller protectors and a tank pad.
