The biggest news for KTM this year is the all new 2018 KTM 250 XCW TPI. This is KTM's very first attempt at offering a fuel injected 2-stroke. TPI stands for transfer port injection and according to KTM this system comes with two injectors making for a smoother ride.
They are also boldly claiming that this TPI system will dramatically reduce fuel consumption (Going to be a fun test).
Here are the pictures:
2018 250 XC-W TPI Highlights
NEW 249cc 2-Stroke engine fitted with a patented TPI fuel injection system for perfect fueling at any altitude, no premixing and reduced fuel consumption while still living up to the standard of a KTM 2-stroke.
NEW Cylinder with two injectors placed in the rear transfer ports for excellent downstream atomization of fuel.
NEW EMS featuring a new ECU controlling ignition timing and fuel based on information from 5 sensors reading intake and ambient air pressure, throttle position, oil and water temperature for optimized engine response.
NEW 39mm throttle body by Dell’Orto features a butterfly valve controlled by a twin cable throttle.
NEW electronic oil pump feeds oil from the 700cc oil tank to intake to ensure a perfect fuel-oil mix under any condition while reducing smoking by 50% for up to 5 tanks of fuel.
UPDATED WP Xplor 48 upside-down split front fork with new outer tubes for more sensitivity, less stiction and reduced weight. Revised settings are stiffer as well.
UPDATED WP Xplor PDS rear suspension features stiffer settings while still offering the progressive feel and excellent bottoming resistance only PDS can provide.
NEW radiator guards provide better airflow in muddy conditions.
Engine cases feature a compact shaft arrangement for better mass centralization.
Cylinder with twin-valve controlled power valve for smooth power that can be adjusted within seconds for different track conditions.
Revolutionary lateral counter balancer reduces engine vibrations for less rider fatigue at the end of the moto.
6-speed wide ratio transmission is perfectly suited for off-road duty
Hydraulically operated DDS clutch features a damping system for better traction and durability.
Lightweight Chromoly steel frame provides high torsional rigidity with less longitudinal stiffness resulting in excellent handling and energy absorption
PDS Shock mounting geometry is matched to the aluminum swingarm with a centered location for nearly symmetrical loads to the swingarm.
Forged aluminum triple clamp with handlebar positions and a 22mm offset for precise handling.
ODI grips that feature a lock-on design for the left grip and a vulcanized grip on the throttle side.
“No Dirt” footpeg design keeps the pegs pivot from becoming clogged, ensuring the footpeg is always in the correct position.
CNC machined hubs, high-end Giant rims and Dunlop tires for maximum strength and traction
Airbox and filter design provides maximum performance with fast “no tools” air filter changes.
Bodywork with perfect ergonomics and contact points for maximum control and comfort.
2.4 gallon see-through polyethylene tank provides the range needed from a true READY TO RACE enduro bike.
“No Dirt” shift lever prevents dirt from fouling the lever joint to ensure proper shifting in any condition.
