In July we broke the news of a new racebike from KTM, the RC390, which is to be used in a spec racing series in 2014. Now, we’ve received leaked information from KTM Duke 390 forum member sandy_mary with technical specs about the road going production model.

Pulled from a secret page on KTM’s Canadian website, according to sandy_mary, here’s what we’ve found out.




The engine is the same 373cc, liquid-cooled, four-stroke single used in the Duke 390. Bore and stroke measure 89mm x 60mm and is claimed to put out around 43 hp. It’s mated to a six-speed transmission, with multi-plate wet clutch.




The RC390 carries on the KTM tradition of a tubular steel trellis frame, with WP suspension at both ends. Front fork measurement of 43mm is the same diameter as the RC8R, while a 23.8-degree rake and 52.8-inch wheelbase means it should be pretty agile. Seat height is reported to be 32.3 inches.

We can also see in these pictures single brake discs, with front measuring 300mm, rear 230mm. A four-pot, radially mounted Brembo caliper is mated to the front, with a single-piston unit in back. The RC390 will come equipped with ABS, with the option to turn it off at will. Fuel tank capacity is a paltry 2.6 gallons, and the RC390’s reported dry weight is 324.1 pounds, 79 of those pounds residing in the engine alone.

The RC 390 keeps the basic looks of its Cup sibling, which itself is highly stylized after the RC8. Blinkers are integrated into the mirrors for a clean look, and the twin round headlights give the bike a distinctive appearance vaguely reminiscent of an old Aprilia RSV Mille.

There’s no word yet on pricing, but expect it to slot in slightly above the Duke 390. We’ll bring you more details as we get it, but for now, take a look at these early pictures and tell us what you think of the RC390 in the comments section below.
