Starting via the button is instantaneous, and we never had to fiddle with the cold-start button. AT81s are mounted up both fore and aft. The filler cap assembly for the oil tank is located between the fuel tank and steering head, utilising a hose in the upper frame tube to conduct the oil to the storage container. We also did some major-league hill-climbing, and here the bike showed a strong blend of power with enough on top to keep the wheel spinning on sand climbs. Make sure that you use the proper oil in the injection system.
Super strong kt to good feel. Out back, the AT 81 works nicely in roots, rocks and hardpack. The starting system is superb. D Dirt Star rims.

This type of frame design provides high torsional rigidity for best handling and rideability, while a certain longitudinal flexibility can absorb the wheel impact energy, supporting the suspension for reduced rider fatigue. We are not tip fans of the stock rims. Larger riders and high-end aggro youngsters will have to go stiffer. Brembo brakes and Wave rotors handle the stopping duties.
We only got the to steam hard on one horrendously long hill.
The ODI grips are excellent. The power valve is actuated by exhaust gases that force it open as they increase in velocity and gpi harder against the flap or valve. The diaphragm spring also leaves sufficient space for a damping system integrated into the clutch hub, which benefits both traction and durability.
It gets a big wow. Stalling was never an issue, and the nastier terrain showcased the strong bottom-to-mid power, which is the heart and soul of the bike. The rear subframe made of lightweight aluminium sections is connected to the frame with four bolts and weighs g.
Second and third are great trail cogs, and with hill-climbing, it depended on the lead-in to the mountain. Utilising various sensor data such as intake and toi air pressure, kgm valve position and water temperature, the control unit optimises ignition timing and the amount of fuel to inject. KTM has this dialed in via the lithium-ion battery and a tidy starter motor. But, every once in a while, it sits on the only chair left in the theatre.
Benefits in brief Reduced fuel consumption. A cold start device is also provided, opening a bypass to ti extra air.
3000 This is where the bike is cleaner, as there is less unburnt fuel, more effective combustion and fewer emissions. The goal is to provide the machine with usable power that expands as the engine revs. The Xplor fork uses springs in both legs, features separate damping functions for each leg compression: Faster conditions demonstrate that the Xplor fork is better on the big hits, but it dives and wallows far too much for an aggressive rider.

If anything, it feels maybe a skosh lean here, but as you transition into the upper pull, it yanks long and hard. It uses a large Twin Air filter element mounted on a rigid cage which at the same time forms the air filter box bracket.
But, it has a small chink in the armor in the midrange where it feels lean. For optimal mass centralisation, the lightweight, die-cast crankcases hold the clutch shaft and the crankshaft in a high position close to the centre of gravity 30 the handling of the bike. The oil-injection system is said to reduce up to half of the smoke from the exhaust system over carbureted models and has a capacity of 0.
Reduced fuel evaporation, which also means less fuel smell in tip vehicles. While engine power remains at the same level, the power delivery is much more homogeneous. Premix fuel with 2-stroke oil is also a thing of the past, and the fuel efficiency increases dramatically. For a smooth and well-controlled power delivery, the exhaust control of the carbureted EXC models is also retained.
The testers liked it. The ones with cranky knees screamed for a taller saddle. The cylinder features two lateral domes that hold the fuel injectors and supply fuel to the rear transfer ports.
