RC 8C 2022
The KTM RC 8C is an ultra-lightweight, bespoke track weapon designed with one simple purpose - to decimate lap times and stamp orange authority on the starting grid. With only 100 of these rare weapons going into production, the KTM RC 8C is a highly limited, unique motorcycle aimed at a special type of rider who knows how to get his, or her, elbow down.
Rocketing the KTM RC 8C off the line is a ultra-potent, lightweight and compact 128 hp 889 cc LC8c engine. If that sounds familiar, its the same, celebrated powerplant found in the KTM 890 DUKE R, but with more focus on more and drive out of corners. The benefit of using a production engine is easy maintenance and parts availability, without sacrificing on performance.
Dominating the dash area is the 5" TFT display AIM MXS 1.2 RACE dashboard and data logger with integrated GPS function. The dashboard displays lap times and live information like best laps, fastest sector times and more. More importantly, the data is logged into AIM RaceStudio where riders or race teams can analyze everything from speed, position on track, throttle position and mechanical running temperatures.
Slowing the KTM RC 8C down comes courtesy of Brembo's finest, high performance and lightweight components, namely BREMBO STYLEMA front brake calipers grabbing 290 mm fully floating brake disks with aluminum rotor carriers and titanium brake caliper screws.
At this level of refinement, only the very best WP Pro Components will do. That is why the KTM RC 8C boasts suspension which is hand assembled in a special department at the WP headquarters - the very same place responsible for the assembly of the KTM RC16 suspension.
Boasting some of the lightest wheels on track, the KTM RC 8C makes use of lightweight Dymag UP7X forged aluminum wheels - 3.5" x 17" on the front and 6 "x 17" on the rear - which ensures optimum acceleration and handling while being suitable for real world use on the track. Theyre practical too, with a quick change assembly and axle that allows wheels to be swapped out without disassembling the brakes.
Developed without compromise for the race track, the KTM RC 8C features a chromium-molybdenum steel trellis frame, which is precision engineered and hand finished to be ultra-stiff, pin-point precise and lightweight. Like the greatest of race machines, the frame also offers a multitude of adjustment settings.
Providing the bark to the KTM RC 8C's bite, is a bespoke stainless steel racing exhaust with an Akrapovic titanium muffler with a carbon end cap. Equipped with a decibel killer designed to tame the twin-cylinder symphony from 105 to 103 dBA, but should local track requirements dictate it, an alternative 98 dBA muffler can be ordered separately.
The 8 valve DOHC cylinder head contains twin chain driven camshafts, a spark plug per cylinder and camshafts that have been assembled rather than forged, making them lightweight. The steel valves - 37mm intake and 30 mm exhaust - are opened by DLC coated finger followers, for smoother operation and the timing chain is tensioned by a hydraulic chain tension adjuster. It's smooth too, thanks to a secondary balancer shaft which is actuated by the exhaust camshaft, between the two camshafts.
Lightweight and pressure lubricated, the slipper clutch on the KTM RC 8C features improved cooling and reduced friction over other units. The slipper clutch opens when the engine back-torque becomes too high, it also assists when you open up the throttle. The former prevents destabilizing rear wheel chatter when braking sharply or decelerating, while the latter reduces the hand force required for changing gear, allowing the clutch to be controlled with the little finger - saving you energy when riding. The clutch is also cable activated for further weight reduction.
The electronic fuel injection system on the KTM RC 8C features sensors in each throttle body which measure the manifold pressure and adjust the mixture accordingly per cylinder. Two dedicated engine mappings are available, wet and dry, that can be easily selected from the handlebar.
