01. Engine & Exhaust

Engine
Producing 125 hp (92 kW) peak power, the high-performance, compact 1050 cc V-twin engine sits in a lightweight chassis, which puts the 1090 R at the top of its class in terms of power-to-weight ratio and ride dynamics. With advanced but proven technology including twin spark ignition, ride-by-wire, and traction control (TC), a smooth, controllable power delivery is assured.


Slipper clutch
Not only does the slipper clutch open 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; the latter reduces the lever force required for changing gears, allowing the clutch to be controlled with one trigger-happy finger – saving you energy while riding.


Cylinder Heads
An absolutely key element in the smooth power delivery of the 75° V-twin is each cylinder’s state-of-the-art 4-valve cylinder head. These combine twin plug ignition, flow-optimized ports and a slick low-friction valve drive train with cams from each cylinder’s twin overhead camshafts driving DLC-coated cam followers.

DLC coating
DLC (Diamond-Like Carbon) is an extremely hard, durable coating used in many engine parts, ie: cam followers, to assist sliding behavior. It improves performance and our engines love it!

Twin ignition
The twin plug ignition system controls 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: greater controlled power, lower fuel consumption, and lower emissions. Better for everyone.


Pistons
The forged piston design of the KTM 1090 ADVENTURE R is borrowed from Formula 1 technology. The pistons are five millimeters smaller in diameter and 21 grams lighter compared with those of the 1290 SUPER ADVENTURE R, which means reduced reciprocating weight. This helps maximize the responsiveness and free-revving nature of the engine. The piston skirts have an additional state-of-the-art, Gravel® finish. Not only does this minimize friction, it is also particularly hardwearing, which improves durability.


Ride-by-wire
Smooth throttle response is what you get, beyond simply being free of a throttle cable, which is why the KTM 1090 ADVENTURE R's ride-by-wire system is so attractive. It ensures perfect dosage of the readily available and plentiful torque and also electronically translates rider throttle commands into throttle valve positions, which are perfectly adjusted to suit different riding conditions.


Long service intervals
A unique mix of the highest quality components combined with a fully developed and reliable engine allows extremely long service intervals of 15,000 km. That’s a lot of adventures.


Power-to-weight ratio
The combination of lightweight chassis engineering and a compact but powerful engine take the KTM 1090 ADVENTURE R to the top of its class in terms of power-to-weight ratio and ride dynamics. Its weight of only 230 kg, while carrying a substantial 23 liters of fuel, makes the KTM 1090 ADVENTURE R – in typical KTM style – one of the lightest motorcycles in its segment. Add an outstanding geometry, well-balanced stiffness distribution and high quality suspension components and you end up with a bike that can handle almost anything. This also boosts safety, since it is far easier to fling a lightweight, nimble motorcycle around a source of danger than a heavy one.

Cooling
On long offroad explorations it’s important the V-twin engine keeps its cool to ensure its advanced power and performance are maintained. Thanks to the KTM 1090 ADVENTURE R’s design and advanced cooling technology, riding for hours in hot conditions is possible.
