KTM 300 EXC 2015

The "big" two-stroke engine was newly developed in 2017 and is used on the 250 and 300. The electric starter is no longer "flange-mounted" but compactly integrated. Professionals have said that the 300 is actually too powerful for them. For me, however, it is THE 2-stroke recommendation, especially for hobby riders. With the map selector, you can choose the "mild" mapping here and also fall back on the weaker spring for the exhaust control. In practice, you can ride it in a gear higher than the 250 and it becomes quite tame. The new balancer shaft offers a big plus in ride comfort: significantly less vibration!

High performance in combination with lively handling

simple design - thus hardest to handle under extreme loads

lower vibrations due to new motor with balancer shaft

Compared to the four-stroke, still more strenuous to drive on long stages

engine response "good" but just not as clean as with the four-stroke

The KTM 390 Duke is a "real" Duke. The trademark: Extremely agile handling that makes for powerful riding fun. The flyweight 390 can be precisely controlled with its narrow waist and wide handlebars and feels most at home in tight corners. Especially with the Supermoto mode, it is a fun machine without equal. Unfortunately, only the brakes and suspension of the 390 cannot maintain the same, very high performance level as on the 125 Duke or 890 Duke. They feel a bit spongy and not optimally tuned, especially when the rider weighs in a bit more. The equipment is otherwise tip-top, especially when you consider the price of the 390 Duke. In terms of riding pleasure/euros, it outperforms most, including its Duke sisters.

Typical Duke ergonomics that are also suitable for taller riders

Extremely agile handling thanks to flyweight and narrow waist

Sporty engine with great handling

Modern TFT display with smartphone connectivity

Supermoto mode is a pleasure

Quickshifter (optional) works perfectly

Adjustable hand levers

Top price-performance ratio for A2 motorbike.

Chassis tuned a little too soft

pressure point of the brakes a little spongy
