KTM 790 Duke 2026

KTM 790 Duke 2026

The 2027 KTM 790 Duke isn’t a completely new bike, but it feels like a much-needed fresh start. The familiar twin-cylinder engine delivers 95 Horsepower – more than enough power for country roads – the new WP suspension suits its sporty character, the brakes are finely modulated and the ergonomics have been noticeably improved. The unpainted decals show that this bike was developed with a focus on cost-effectiveness. And taller riders should check the knee angle. However, these are not issues that detract from the overall package.

A powerful and practical twin-cylinder engine delivering 95 horsepower and 87 nm

a very well-balanced WP suspension with a sporty base set-up

new ergonomics with an open handlebar and good ground contact

no more ‘demo mode’ in the electronics packages

a target price of under 10,000 euros makes it very competitive

Below 3,000 rpm, the engine may jerk slightly

the optional cruise control cannot be deactivated by turning the throttle grip anti-clockwise

taller riders should check the sportier knee angle

unpainted stickers highlight the pressure on pricing

Quickshifter Plus, cruise control and Track mode remain optional
