KTM 690 Duke 2014

KTM 690 Duke 2014

More than a decade after its launch, the KTM 690 Duke remains a fascinating bike with its own character. The attempt to turn the rebellious Duke into a bike with more mass appeal has proven to be a successful strategy. The combination of an outstanding LC4 engine, direct handling and good value for money continues to make it an attractive option for riders looking for something special. Although newer twin-cylinder models are superior in terms of smooth running and comfort, the 690 Duke offers an immediacy and character that only a large single-cylinder can deliver. As a used motorbike, it has proven to be surprisingly stable in value and durable - provided you pay attention to regular maintenance.

Outstanding LC4 single-cylinder engine with a unique character

Outstanding power-to-weight ratio (2.29 kg/HP)

Direct, precise handling in all riding situations

Good value stability and surprising longevity

Disengageable ABS and effective anti-hopping clutch

Low fuel consumption (3.5-4 litres/100 km)

Suspension without adjustability with limited reserves

Mediocre shifting precision, especially at higher mileages

Alternator as a potential weak point at higher mileages

Clutch play needs to be adjusted more frequently

"Whipping" chain at very low speeds in the partial load range

Slight vibrations at higher speeds (especially before 2016)
