Remember Ducati's gorgeous little Superquadro Mono big single-cylinder engine? It was clearly a gauntlet thrown over international borders, from Bologna to Mattighofen—and it looks like KTM is ready to respond in kind.
Yes, even though it's going through insolvency proceedings right now. Remember, motorcycle R & D is cyclical and ongoing. Projects start back in the labs and on the dynos months and years before they ever make it into public view, so it's highly likely that KTM has been working on this since well before its business problems first became public.
Moto-Austria is a motorcycle industry trade show that takes place in Austria each year, and it's here in 2025 that KTM chose to show off its engine evolution. The engine in question is the next iteration of its tried and tested LC4 big single-cylinder engine, which you might remember from such hits as the 690 Enduro R.
