KTM 125 Duke 2020

KTM 125 Duke 2020

If you want an aggressive design, sporty and good handling as well as higher performance, especially in the upper rev range, you can't go wrong with the Duke. The attention to detail, for example in the form of the LED turn signals or the elaborate and multifunctional TFT display, are a KTM trademark. The only drawback is that it lacks a little power in the lower rev range.

Good chassis

LED indicators and headlights

TFT display

Little power in the lower rev range

The Yamaha YZF-R125 in the 2019 version makes journalists' lives difficult. You search and search for a fault, but can't find one - simply frustrating! Because the 15 hp single-cylinder with variable valve timing (VVA) performs excellently and is undoubtedly one of the best power units in the 125cc class. The handling is convincing in everyday life as well as on the racetrack, even if the chassis shows its sporty side on bumps. But we are on a super sports bike, so that is not a serious point of criticism. Maybe I need to ride the R125 for a few weeks to find its Achilles heel after all....

excellent engine

cool looks

sporty chassis

very potent on the racetrack

very good supersport package

unfortunately nothing
