Engine

A state-of-the-art, liquid cooled, single-cylinder, four-stroke 250 cc engine gets you started in KTM’s exciting world of ADVENTURE. The engine is equipped with an electric starter and delivers a smooth power for playful exploration. Twin overhead camshafts, four valves and electronic fuel injection are integral to the KTM 250 ADVENTURE’s power delivery and together with a balancer shaft, they ensure the highest levels of smoothness. Its lightweight and compact construction facilitates straight air intake channels, allowing for a shortened distance for air to flow into the combustion chamber, and beyond for gas to flow to the two catalytic converters. Besides the faster movement of air and gases, it also allows the engine to warm up faster. Additionally, the two catalytic converters and the fuel tank ventilation system (EVAP system) improve emission values and prevent fuel vapors from being released into the environment, making the KTM 250 ADVENTURE extremely eco-friendly and compliant with the strict EU5 exhaust emission standards.

Slipper Clutch

The slipper clutch is a unique feature that saves power and helps in slides. It opens when the engine back-torque becomes too high, preventing annoying rear wheel chatter when braking sharply or decelerating and gives the wheel just that little bit of braking for a controlled rear wheel slide. It also closes with the force of the clutch springs when the throttle is opened, allowing the clutch to be pulled with the little finger, which saves energy when riding.

Piston

The 72 mm bore piston is DLC coated for extra durability. It performs a stroke of 61.1 mm, which results in a displacement of 248.77 ccm and produces a compression ratio of 12.5:1. The crown is cooled by the oil spray nozzle, while the piston uses a continuous, low-friction, nicasil-coated aluminum wet bushing with open-deck design.

Cylinder head

State-of-the-art DOHC (Double Overhead Camshaft) technology. The four valves in the cylinder head of the KTM 250 ADVENTURE are actuated, via durable finger followers, by two overhead camshafts. This design is one of the preferred performance solutions of many offroad models, including the successful KTM 1290 SUPER ADVENTURE. It is not only renowned for its extreme reliability, but also offers low friction, thanks to the ultra-hard DLC coating on the finger levers – a solution that makes this engine super reliable, even when pushing for longer at high RPM.

Electronic fuel injection

The 250 ADVENTURE is fitted with a modern engine management system featuring BOSCH electronic fuel injection in conjunction with a DELL’ORTO 38 mm throttle body. The system guarantees perfect throttle response, excellent fuel efficiency and low exhaust emissions.

Gearbox

The KTM 250 ADVENTURE is fitted with a robust 6-speed sequential gearbox. The gear ratios fit perfectly to the power band of the 250 cc engine and allow you to smoothly select the perfect gear, whether it be flowing street rides or more challenging offroad escapes. 

A2 License

The KTM 250 ADVENTURE matches all the A2 driver´s license requirements.

Exhaust

The KTM 250 ADVENTURE features a lightweight and precision-crafted exhaust system comprising of stainless steel header pipe and pre-muffler leading the exhaust gases to a slim silencer. The silencer features a light aluminium sleeve and has been positioned close to the bike’s overall center of gravity without disturbing the rider when moving on the bike. It improves balance and handling, whilst also delivering smooth, instant power. The pre-muffler is made from stainless steel. Two catalytic converters are integrated in the header pipe and pre-muffler respectively bringing the exhaust emissions down to Euro IV level.

Frame

Similar to the race proven frame of the KTM 450 RALLY, the KTM 250 ADVENTURE features an ultra-lightweight, yet extremely stable trellis frame. It exceeds all requirements for stability and controllability and is the backbone of this nimble adventurer. The forgiving balance of flex and stiffness, combined with a wheelbase of 1430 (+/-15.5 mm) and a 63.5 degree steering head angle, clearly suggest an offroad oriented layout. It is also the basis of its outstanding straight-line stability and precise and agile steering behavior.

Subframe

The removable, steel trellis subframe is fixed to the main frame with 4 screws. It was developed to be compact and lightweight, but strong enough to carry a passenger and luggage, while negotiating the tough conditions that can be expected when adventure riding.

Swingarm

The die-cast, open-lattice swingarm is a signature element of the KTM ADVENTURE range. It is precisely manufactured with an optimized stiffness, while still offering excellent flex characteristics. The rear shock links directly onto the swingarm, reducing complexity and parts, while also enhancing the feeling of the bike’s behavior for the rider. The relatively long swingarm provides enough space for any suitable offroad tire.

Rider Aids

KTM develops electronic rider aids that provide more control and better performance for riders of all levels of ability, with the intention of enhancing the fun in all conditions.

Offroad ABS

Riding adventure is about traveling long distances and venturing into the unknown, so having a bike that backs you up in extreme situations is very important. Regular ABS is developed specifically for the street, therefore an offroad ABS function has been added to improve braking control in offroad situations. In this mode, ABS is deactivated on the rear wheel, while ABS activation on the front wheel is reduced. This means riders can lock up the rear wheel, allowing them to steer the rear end into corners. It also prevents over regulated front wheel braking, or the opposite of too much front brake pressure, ensuring the best stopping power in the dirt.
