KTM 1190 RC8 R 2013: ONE OF THE WORLD'S MOST POWERFUL V2SRetour aux Bikes Avantage suivant
With its 129 kW (173 hp) of power, the V2 on the KTM RC8 R can be considered as the measure of all things for ultra-sporty twins, with maximum performance, predictable characteristics and high reliability. The KTM engine impresses with an extremely broad rev range and spontaneous throttle response, while supplying supreme ride quality.
Saves power, helps in slides: The new anti-hopping clutch not only opens when the engine back-torque becomes too high, it also closes with the force of the clutch springs when you open up the throttle. The former prevents annoying rear wheel chatter when braking sharply or decelerating – and gives the wheel just that bit of braking for a controlled rear wheel slide. The latter allows the clutch to be pulled and controlled with the little finger – which saves energy when riding.
The main reasons for the outstanding performance of the RC8 R 2013 V-twin with 75° cylinder angle are the state-of-the-art cylinder heads with twin plug ignition, flow-optimised ducts and cam follower drive for the valves (intake: titanium; exhaust: steel). For tuners: Valve timing is adjustable via the camshaft gears.
TWIN PLUG IGNITION
The twin plug ignition system on the latest RC8 R fires the two differently sized spark plugs in each cylinder head independently of each other in such a way that more efficient combustion and a smoother, optimally controlled combustion sequence are achieved at all times. The result: even more and even better controlled power, lower fuel consumption, and less emissions.
INJECTION / ENGINE MANAGEMENT
The electronic Keihin engine management with twin throttle valves regulates the modern electronic fuel injection system on the 2013 KTM RC8 R, focussing on maximum power with predictable power development and spontaneous responsiveness with precisely controllable throttle response.
The forged piston structure on the RC8 R, borrowed from Formula 1, results in a high loading capacity, despite the extremely short and lightweight design. This minimises the reciprocating weight and optimises the responsiveness and free-revving nature of the engine.
The smooth shape of the crank webs on the latest KTM RC8 R results in low-loss running of the crank drive; the modified weight distribution of the crankshaft and a newly dimensioned alternator rotor improve the smooth running of the engine. Together they optimise the load change behaviour of the engine.
