KTM 125 Duke 2018

KTM 125 Duke 2018

Even in its second generation, the KTM 125 Duke is still the highest-quality overall package in the 125cc naked bike class. Its looks stand out and its equipment is similar to that of larger and significantly more expensive KTM models. As is typical for KTM, the handling comes from the supermoto league, which makes the 125 Duke a real fun machine in tight corners. However, the Orange from Mattighofen should not relax too long on their laurels, because the competition is strong and is already beginning to overtake the ever-popular KTM 125 Duke in some aspects.

The Suzuki GSX-S125 feels more grown-up than the identically constructed GSX-R125. It is slightly wider around the tank and does not need a fairing for a maximum speed of about 120 km/h. Technically, it is identical to the GSX-R, but with higher and wider handlebars and thus a more upright position. Technically, it is identical to the GSX-R, but it is more fun with the higher and wider handlebars and the resulting more upright riding position. A wheelie is pretty easy to do, so you can do without a few km/h of top speed.
