New KTM RC 390

The new KTM RC390 is set for an early November reveal at EICMA show in Milan, but its fans don’t have to wait that long to find out what the new KTM has in store for them. The images and spec details have been leaked from the motorcycle manufacturer’s Canadian website, and we have a number of details on the now A2 legal bike. Yes you read it right. Unlike the D390 which needed a restrictor to be A2 legal, the new RC390 at 147kg and 43PS (32KW) peak power just about manages to stay under the 0.2KW/kg power/weight ratio mandatory for a bike to be A2 legal. What that also means as a subtext is that the Duke 390 (naked) will have a better power to weight ratio than the new faired version.

Another significant change from the Duke 390 is the brand new clip on handlebars that enable a sportier and aggressive riding position. This coupled with the new and visually appealing forged aluminium triple clamps – required to accommodate the new steering angle – promise a more focused, compact and sporty setup which sounds right for small and light sportsbike.

 The RC390 gets the same single-cylinder, liquid cooled 375cc four-stroke engine as the Duke 390. The brilliant engine comes with twin overhead camshafts, four valves and electronic fuel injection delivers 43PS max power and thanks to the balancer shaft, delivers the highest level of smoothness. The engine is equipped with an electric starter powered by a 12V/6Ah battery. We are currently expecting the gearing to remain more or less the same at the gearbox level as well as at both sprockets for this bike. But final gearing figures, expected early November, will determine how the nature of the performance will be articulated.

 Other significant changes include a new 9.5 litre steel fuel tank with 1.5 litre reserve, specifically developed for the RC, brand new twin headlight for the supersport look and integrated blinkers.  It also gets a brand new bodywork, footrests and pedals that help the RC take up fast cornering by allowing a greater leaning angle.

 The telescopic fork, 100 per cent digital LCD display with a shift light indicating the best moment for shifting up, the light alloy swing arm, 17in alloys with Metzeler tyres (110mm front, 150mm rear), and ABS are standard
