Sport

The GSX-R 125 took its time in upgrading to Euro5. Understandably in no hurry. The operation put 3 kilos on its stomach and slightly modified the engine data. Torque and power are preserved, provided you go for them at 500 rpm higher. Suzuki has discreetly redesigned the boot, certainly to accommodate the new catalytic converter.

15 horses and a small displacement, but a mythical name. This bike has an exceptional heritage in its retrospect. The GSX-R line has seen it all in circuit racing, won it all, taken it all. From the finest victories to bitter disillusionment, through unspeakable speeds and moments of doubt, the 'Gex' has weathered the years until its name has become almost mythical. After exploring a wide range of displacements, from the 50 cm3 to the 1340 Hayabusa, and especially the 750 cm3, Suzuki now offers it in a 125 cm3 configuration. At last, a small sports bike for young people, bearing the famous red R.

The GSX-R 125 had been rumored for some time. Echoes leaked out, but the manufacturer said nothing. Until the machine made its official appearance, surprising observers and immediately positioning itself as a machine to be reckoned with. This arrival had to command respect from the outset. Suzuki announces that its little GSX-R will boast an excellent power-to-weight ratio. Its silhouette makes you believe it without batting an eyelid: with its feline look, its design that finely reproduces the GSX-R codes and its eye-catching face, the youngest of the gex models can proudly stand next to its big brothers.

Sporty, yes, but not as sporty as some of the more aggressive models. For example, there are no inverted forks or radial calipers like on theAprilia RS 125. Instead, we have a conventional fork, an axial jaw and one brake disc per wheel. With ABS as standard. Enough to keep the engine's power in check. Suzuki's approach is not one of showmanship, but of efficiency. A classic, modern 4-stroke, single-cylinder, 4-valve, fuel-injected, double-actuated, liquid-cooled engine takes care of the overall velocity. According to the legislation, 15 grunts are expected at 10,500 rpm. To make the difference, Suz has announced that its 125 has the smallest frontal area in the category, and that the fairing parts are lighter than those used by the competition. The result is better acceleration and lower fuel consumption.

Suzuki GSX-R 125 in addition to its incisive, engaging styling, the 125 GSX-R also boasts a number of distinctive features. A closer look reveals petal brake discs, a breathtaking exhaust system with twin tailpipes, LED headlights, an all-digital instrument cluster (simplified) based on the styling of the latest 1000 and, as a surprising refinement, the bike can be started without a key.
Well, yes, there is a key. But with contactless technology, just like on much higher-end motorcycles. All you have to do is carry it in your pocket, turn the switch and a simple press of the right thumb is all it takes to shake the mono. With the Suzuki Easy Start System, the starter remains engaged until the engine starts.

Alongside the R 125, Ninja 125, Aprilia RS 125 and KTM RC 125, the category will have to reckon with this player with a prestigious name.

French Boby Model 2024
Very nice 125 I bought the one of 2023 to my wife I am satisfied Good top speed 125 to 135 km hour easy I did not even reach the breaker so very surprising for a 125 The colors of this year are very pretty I just ordered the one of 2024 white and blue For this year I trust again in Suzuki which did not disappoint me level reliability Rating : 5/5
French darky Model 2017
super 125cc bike i've had it for a month now . the instrumentation is great and fun to ride i recommend it for those who want to start riding . Rating : 5/5
French Guillaume Model 2018
Very nice. The ABS is useful whatever the engine size and is a real plus.
The clutch is super-smooth, which is also a rare comfort.
Rating : 4/5
French Jeff2A Model 2018
Virtually no added value compared to the YZF released 10 years ago. What's the point of ABS on a 125 that's struggling to reach its original 130 odometer? Conventional braking is more than enough. I really don't regret getting my A license. The 125s of 2018 are no longer those of the 1980s, which produced almost 30 hp with 120 kg max! Rating : 1/5
very nice little bike, as soon as it comes out I'll buy it, finally a new 125 too neglected by manufacturers in France
because you can have fun with small machines
thank you
