KTM is celebrating ?30 Years of Duke? this year, and we?ve already reviewed two updated models, the 390 Duke and 990 Duke. We?ve saved the best ? and biggest ? for last, the 1390 Super Duke R Evo. Known for years as ?The Beast,? the Super Duke gets a displacement bump from 1,301cc to 1,350cc (hence the evolutionary name change from 1290 to 1390) and other upgrades for 2024. KTM says it?s 60% new.

With an extra 10 hp and new cam shift technology, the KTM 1390 Super Duke R Evo’s engine delivers more performance throughout the rev range.

To achieve the larger displacement, KTM bored out the Super Duke?s twin cylinders from 108mm to 110mm but left stroke the same at 71mm. There?s also a new cam shift system that alternates between two different valve lifts above and below 5,700 rpm, allowing for both a deep well of low-end torque and a screaming top end rather than having to compromise between the two. The 1390 Super Duke R Evo?s liquid-cooled, 75-degree LC8 V-Twin now makes a claimed 190 hp (up from 180) at 10,000 rpm and 107 lb-ft of torque (up from 103) at 8,000 rpm, all while meeting Euro 5+ homologation.
