A German outlet photographed what appears to be a KTM 790 RC prototype testing in Austria. Beneath temporary 990 RC R bodywork, it identified a 790 Duke-style swingarm, high exhaust and WP brakes. A 105 PS LC8c engine is considered likely, but the final design and launch timing remain unknown, with development potentially taking up to two years.

For me, the bigger clue is not whether it makes exactly 105 PS, but that an Aprilia RS660 was reportedly used as a reference bike. If KTM wants a road-going sport machine that works from corner entry to exit, a scaled-down 990 will not be enough. Front load and damping around the 790 Duke chassis will define its real track character.

With no launch timing, I will wait without getting carried away.

Filling the gap between the RC390 and 990 would make a neat lineup.

Around 105 PS could hit a sweet spot between the road and track days.

The 990 RC R bodywork is temporary. Calling this the final design is way too early.

It is fascinating how people identify a prototype from individual parts.

If the 790 RC really happens, I want it tested beside the RS660.

If the RS660 is the benchmark, weight and price will decide it.
