KTM RC 390 2014-2016 Service Manual

Rider Magazine's own first-look coverage confirms exactly what inspired KTM to build this bike in the first place: "KTM takes its 'Ready to Race' motto to heart. It has been the spec manufacturer for the Red Bull Rookies Cup since the series debuted in 2007, running the two-stroke KTM RC 125 for the first six seasons and the Moto3-spec four-stroke KTM RC 250 R for 2013 and 2014... such success motivated KTM to develop a nearly race-ready, small-displacement sportbike that is street legal." Motorcyclist's own launch review confirmed the genuine industry excitement around this bike's arrival in America specifically: "this latest KTM is ready to take on the street, the track, and everywhere in between...and we're thrilled that it's bound for America."

Power comes from a 373cc (documented at launch as 345cc by Rider Magazine, later confirmed at 373cc across most sources) liquid-cooled DOHC single-cylinder engine, 4 valves, an 89mm bore and 60mm stroke, and electronic fuel injection through a 46mm Dell'Orto throttle body, delivering a claimed 44 hp at 9,500 rpm and roughly 26 lb-ft (35 Nm) of torque at 7,250 rpm. Rider Magazine's own detailed engineering account confirms the genuine race-derived internals behind that engine's short-stroke design: "designed for performance, the engine has a forged piston, a Nikasil coated cylinder... KTM says the short-stroke engine... weighs just 79 pounds." Autoevolution's own confirmed spec sheet notes this exact platform "packed the same 373cc engine as the 390 Duke" — genuinely the same fundamental powerplant KTM used across its whole 390-badged range, tuned identically here in a considerably more track-focused, fully-faired chassis.

Autoevolution's own account confirms a genuine dedicated racing variant Ktm built specifically around this platform: "the maker introduced a racing version of the RC 390 under the RC 390 Cup designation, designed for riders ages 13 to 21 in the ADAC Junior Cup, a MotoGP event. The RC 390 Cup lacked lights, mirrors, and ABS for weight reduction purposes and was fitted with an upgraded WP with a fully adjustable front and rear suspension. The engine was detuned to 38 hp with a block-off plate and was equipped with an Akrapovic exhaust system" — genuinely useful context for understanding this platform's real competition heritage, and a real reminder that a street RC390's ABS-equipped, road-legal configuration differs meaningfully from the stripped-down Cup racer sharing its name and basic architecture.

Autoevolution's own account confirms a genuine mechanical addition arrived at the very end of this exact range: "in 2016, the Austrian motorcycle manufacturer released the KTM RC 390, a sportier version of its predecessor powered by the same engine and fitted with a slipper clutch first introduced in the 390 Duke model" — a real, tangible upgrade specifically for the final model year within this three-year span, worth knowing when comparing a 2014 or 2015 example against a 2016 unit. Claimed curb weight sat at 147kg (324 lbs), with the bike making its US debut at the Long Beach International Motorcycle Show on November 14, 2014, ahead of dealership availability starting March 2015. BikeWale's own collected real-world owner feedback confirms genuine enthusiasm for the platform's character, with one reviewer noting the RC390 "is perhaps the best example to talk about the maturing Indian market — it is bold, exciting and unlike most bikes made in India, does not even attempt to be a one stop solution for all your needs."

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2014-2016 RC 390 running the way it was built to.
