KTM 990 Duke 2025

KTM 990 Duke 2025

The KTM 990 Duke is a bike with rough edges - in the truest sense of the word. It is not the perfect all-rounder, not the most harmonious representative of its class, but it has something that many other bikes lack: real character. Anyone looking for a naked bike that challenges and encourages them, that arouses emotions and makes no compromises, will find a loyal companion in the Duke. It is the bike for individualists, for riders who are looking for something special and are prepared to compromise for it.

Very low weight of just 192 kg

Strong two-cylinder engine with plenty of acceleration

Extremely agile and playful handling

Disengageable ABS on the rear wheel for sporty riders

Surprisingly relaxed ergonomics even for taller riders

Height of entertainment value on winding roads

Engine needs at least 3000 rpm for smooth running

Surcharge-based pricing policy for the electronic driving aids somewhat annoying

Slight tendency towards nervousness - be careful at very high speeds with luggage
