01. Engine & Exhaust
The engine combines powerful acceleration from the very lowest revs with an outstanding free-revving nature and refined engine running. Another big plus: It's extremely economical with fuel.
A lightweight, compact cylinder head contains four valves and a single camshaft placed over the intake valves, with a secondary balancer shaft driven by the timing chain. The intake valves are actuated by finger followers and the exhaust valves by a rocker arm.
A resonator chamber balances out pulses in the intake tract and makes the throttle response smoother with reduced vibrations.
Twin balancer shafts, one in front of the crankshaft and the other in the cylinder head, reduce vibration for a smoother ride.
The lightweight and durable forged piston is designed to reduce reciprocating mass which improves engine response.
Plain bearings are used in the conrod to ensure a reduced reciprocating mass, which helps the engine run smoother and therefore enhances its lively character.
The PASC (Power Assist Clutch) ensures the rider needs minimal input to operate it, due to reduced engine torque transferring to the clutch plates. The slipper clutch prevents rear wheel lock-up under aggressive downshifting, which reduces destabilizing rear wheel chatter on the tarmac when braking sharply or decelerating into turns.
The smooth 6-speed gearbox with Quickshifter+ allows quicker clutchless up and downshifts when you're in the thick of the action. This not only enables the rider to be in more control of the motorcycle by keeping a full grip of the handlebars, but also improves rear wheel traction.
The KTM 690 ENDURO R is equipped with ride-by-wire system, which processes throttle twist grip movements with the help of electronic sensors and activates the throttle valves to control throttle action. This significantly improves the response, giving the rider better throttle control of the potent single-cylinder and a smoother ride.
Injection / Engine Management
Electronic fuel injection and engine management allow performance perfectly suited to the riding conditions. The result: even more and even better controlled power, lower fuel consumption, and less emissions, plus the benefit of features like MTC (Motorcycle Traction Control), MSR (Motor slip regulation), and Quickshifter+. The rider has the choice between two different mappings to influence the engine characteristics. A twin-plug ignition system controls two differently sized spark plugs in the cylinder head independently from each other, for more efficient combustion and a smoother, precisely controlled combustion sequence at all times.
Long service intervals
Besides its fuel efficiency the KTM 690 ENDURO R saves its owner even more money, thanks to long service intervals of 10,000 km.
Annoying rear wheel chatter? This is prevented by the slipper clutch that's fitted as standard.
The exhaust system is made using high-quality stainless steel. It's routed as close as possible to the bike to help with the slim profile, and the exhaust shape has been optimized for hard offroad usage. For 2021, the KTM 690 ENDURO R has some additional hardware, this comes in the form of a new specification of catalytic converter in the muffler. With this addition, the KTM 690 ENDUOR R meets EURO 5 regulations.
Accessing the airfilter during a ride is easy thanks to the airbox being located under the seat. This makes servicing the bike simple, and stress free, when you're off the beaten track.
