FREERIDE 250 F
TRIALS MEETS TRAILS
Who says the adventure can't start right on your doorstep? Whether you live in an urban jungle or a real one, the new KTM FREERIDE 250 F will get you to places you never thought accessible. Wander off safe in the knowledge that its state-of-the-art 250cc DOHC 4-stroke engine has enough power to get this featherweight up the steepest of climbs, while being quiet enough to pass unnoticed. Trial, meet Enduro. World, meet your conqueror.
ENGINE & EXHAUST
The engine of the KTM 250 SX features the latest 2-stroke technology with a counter-balance shaft for low engine vibration, as well as a reliable hydraulically operated DDS clutch. It has a twin-valve controlled-power-valve, which is a major factor in making the KTM 250 SX engine the most competitive 2-stroke in its class. Further refinements to the cylinder and exhaust, make powering through its 5-speed transmission a truly exhilarating experience.
The 6-speed transmission sings perfectly in tune with the power delivery of the 250cc engine and provides a precise and easy shifting action. The new KTM FREERIDE 250 F is equipped with the KTM "No Dirt" gear shift lever, preventing dirt from blocking the joint. The standard final drive ratio is 14:49, and an extra 12-tooth sprocket supplied in a separate enclosure is easily swapped in for riding in especially rough terrain.
The cylinder on the KTM 250 SX has a bore of 66.4 mm and is fitted with a Twin-Valve powervalve system. For 2019, the exhaust port has been machined to provide more precise power valve function, improving overall power delivery. By using two supplied springs, the power characteristics can be changed quickly and easily, ensuring the optimal settings for different tracks and rider preference. The lateral cylinder head brackets are now made of aluminum instead of steel and reduce vibration to levels of insignificance.
ENGINE MANAGEMENT SYSTEM
The state-of-the-art Keihin Engine Management System (EMS) with electronic fuel injection features a new 42mm throttle body. Thanks to its unique injector position, the engine's response gives a whole new meaning to the word 'instantaneous', while contributing to a low fuel consumption. Separate circuits for cold-starting and idle make on-site adjustments easy. Push the throttle back when the engine is warm and the cold start mode disengages. The EMS itself boasts a faster ECU equipped with different mappings for each gear, selected according to the data received from the gear position sensor.
To keep the engine compact, KTM's engineers develop parts that can do more than one thing. The crankshaft, for example, turns a laterally mounted intermediate gear, which in turn drives the timing chain while acting as a balancer shaft and driving the water pump. A hydraulic timing chain tensioner ensures precise and reliable valve timing.
The new KTM FREERIDE 250 F is equipped with lightweight wheels in 21 inches front and 18 inches on the rear, featuring CNC machined hubs and newly designed, high-end aluminum rims by Giant, anodized in black and carrying a FREERIDE logo. These wheels are practically unbeatable in terms of weight, combined with the highest levels of stability.
The Maxxis Trialmaxx OEM tires have been developed specifically for the KTM FREERIDE range. While delivering plenty of traction, they leave much less of an impression in the ground than conventional Enduro competition tires thanks to their high land-to-sea ratio, which means they tear up the tracks less. Their high casings provide appreciably more comfort by supporting the action of the suspension. With their soft, grippy rubber compound, these tires are also great on demanding rocky terrain and when crossing roots.
The KTM FREERIDE 250 F uses the brand new WP XPlor 43 fork, a set of 43 mm upside-down fork legs with 250 mm of travel. With outstanding response and damping characteristics, the new WP XPlor 43 has an even more sensitive feel and enhanced protection against bottoming out. A split fork design with springs on both sides, each of the fork legs houses a separate damping function, with the compression on the left side and rebound damping on the right, both easily adjusted with dials on top of the fork. This allows riders to find their dream set-up with speed and precision - key words at KTM.
At 260 mm of wheel travel, the new WP PDS XPlor shock absorber is a perfect match for the new WP XPlor 43 fork, while saving 430 g of weight over the previous component. The proven and successful PDS rear suspension design (progressive damping system) has become something of a KTM trademark. On the WP PDS XPlor, the progressive damping is achieved by a second damping piston that uses a closed cup towards the end of the stroke, providing increased resistance against bottoming out. This design contributes to optimized progression of the complete rear suspension system, supported by a progressive spring. The suspension is adjustable in compression, rebound, and even offers separate high and low speed compression adjustment. Seat height can be lowered by 25 mm using an optional kit available through the KTM PowerParts program.
Newly designed, CNC machined triple clamps ensure enhanced clamping of the fork, matching the lengthened steering head of the new KTM FREERIDE 250 F's frame. When combined, these new design features increase the rigidity of the complete front end for improved tracking stability.
By reversing the footpeg brackets, the position of the footpegs can be moved 8 mm to the rear. This lets the rider fine-tune the traction and cornering behavior of the bike: the front position means easier cornering, while the rear position yields increased traction.
The long, narrow seat combines unrestricted freedom of movement with excellent comfort. It is easily unlocked and unlatched for access to the tank, fuel filter and electrics. At a seat height of just over 900 mm, the new KTM FREERIDE 250 F offers safe ground contact, even in difficult terrain, especially useful for instilling beginners with confidence and a feeling of safety. An alternative seat with even lower seat height is available through the KTM PowerParts range.
The KTM FREERIDE 250 F features an easy to use dashboard with a new digital speedometer from MAE and numerous features, including integrated warning and indicator lights. For model year 2018, the speedometer cable is well protected in the braided front brake hose tube, which now has an integrated channel. In addition, the bike features now an ignition lock on the right-hand side of the headlight mask next to the speedometer, guaranteeing easy access.
E-STARTER & BATTERY
The 250cc engine comes to life at the push of a button thanks to its reliable E-starter. A new, lightweight lithium-ion battery is used to supply power, saving approximately 1 kg of weight over a conventional lead-acid battery, while providing three times the starting energy. A new battery casing makes sure the high-tech battery is well protected, as well as making it easily accessible.
The new KTM FREERIDE 250 F is fitted with a tapered Neken handlebar made of high-strength aluminum. It has the same bend as the EXC handlebar and compared to the predecessor it is slightly wider for increased leverage. The throttle assembly features a rugged aluminum body with easy free play adjustment, allowing the throttle response to be modified using an alternative throttle cam. The throttle assembly is fitted with a vulcanized grip, while the left side of the handlebar carries a convenient and safe ODI lock-on grip.
When designing this exhaust system, the engineers focused on low noise levels and emissions as well as an outstanding torque delivery for great rideability throughout. The reworked header is routed underneath the engine, protected by the frame and a sturdy bash plate. From there, exhaust gases are directed to the two rear aluminum silencers. Featuring a new anthracite color and a new KTM FREERIDE logo, each of them is equipped with a catalytic converter, effectively reducing both emissions and noise to environmentally friendly levels.
The cooling system routes coolant from the cylinder head directly to the radiator, which is mounted in a well-protected position behind the front frame tube. The radiator fan is now controlled directly by the EMS, eliminating the need for a separate temperature switch.
The KTM FREERIDE 250 F has newly KTM-developed DS clutch (diaphragm steel) with a wear-free steel basket, extremely heat resistant clutch plates and nitrated steel liners. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. Light operation and telepathic amounts of control come as standard with this hydraulic Formula actuated clutch, featuring in addition a 1mm smaller master cylinder.
