We’ve already brought you spy pictures of KTM’s new Duke 890 parallel twin nakedbike but the firm’s latest annual report confirms the project and reveals it contains some interesting technology.
As part of the summary of the firm’s R&D projects, KTM lists “development of a new motorcycle platform based on a revolutionary two-cylinder engine design, which will make a substantial contribution toward opening up new market segments” as one of its projects.
There’s no clue given to what will make the new twin revolutionary. Spy shots of the bike show that it’s a parallel twin, believed to be around 800cc and likely to carry the name Duke 890 when it’s officially revealed. The same engine is sure to find its way into an adventure model as well, and could also be used as part of the push to make KTM’s subsidiary brand, Husqvarna, Europe’s third-largest bike firm by 2020.
In spy pictures there’s little clue to the revolutionary nature of the engine. KTM New Duke 890 looks like it could have a dry sump, but the general layout of the engine and its ancillaries is similar to other mid-sized parallel twins, notably the hugely successful Kawasaki ER-6 engine. So whatever is earning the revolutionary tag is clearly hidden inside. Possible technical innovations might include variable valve timing or a reverse-rotating crank, which would be impossible to see from the outside, but might qualify for revolutionary status.
