Model Description

Light – fast – fun! With all the agility of a 125, the new KTM 150 EXC TPI with fuel injection has the power and the torque to really take the fight to the 250cc 4-strokes. This lively 2-stroke retains the typical low weight, straightforward tech and low maintenance cost. On the other hand, no expense has been spared for top equipment like the hydraulic clutch and Brembo brakes. The benefits of TPI and electronically controlled engine lubrication, combined with the brand-new chassis, make the new KTM 150 EXC TPI the ultimate lightweight enduro for rookies and experienced riders alike.This nimble, lightweight, extreme terrain master is all new for 2020 and now, proudly features the TPI (transfer port injection) letters next to its name making it ready for the strict EURO 4 homologation. This means that there is no longer a need for re-jetting or mixing fuel, making this easy-to-shred thoroughbred even simpler to ride and work on. Already recognized for its supreme agility, the new KTM 150 EXC TPI benefits from a brand-new frame with improved flex characteristics that, together with the many other new changes, helps elevate rider and machine to incredible new levels of competence.

ENGINE

The KTM 150 EXC TPI engine uses cutting-edge 2-stroke technology. Thanks to the revolutionary TPI fuel injection and a newly developed cylinder, the lightest and most compact engine of its kind delivers class-leading power across the entire rev range. Additional benefits include unrivaled agility and a finely controlled power delivery.

ENGINE MANAGEMENT SYSTEM
The 150 EXC TPI features the most modern engine management system (EMS) of any 2-stroke offroad competition motorcycle. The brain of the system is the electronic control unit (ECU) located below the seat. It controls the ignition timing and the amount of fuel injected using sensor data such as intake air pressure, throttle position and coolant temperature. An ambient air pressure sensor enables the ECU to adapt the injection parameters to fast changes in altitude. While riders of carbureted 2-stroke engines need to keep an eye on altitude and temperature and re-jet accordingly, there is no need to set up the KTM 150 EXC TPI for environmental conditions. Should the rider decide to mount an auxiliary radiator fan from the KTM PowerParts program, it will also be controlled directly by the EMS without the need to add an extra thermal switch. An optional map select switch allows the rider to select an alternate mapping for a smoother power delivery, while the standard map provides slightly sportier engine characteristics.
 
EXHAUST SYSTEM
The new KTM 150 EXC TPI is fitted with a new exhaust system featuring a re-designed exhaust pipe and silencer. The pipe is produced with the latest 3D stamping technology and has an optimized shape. In conjunction with the reworked design of the silencer with a new perforated inner tube and lighter damping material, the engine delivers excellent performance with a significant increase in bottom end power, while keeping noise levels safely below the FIM limits. Last but not least, the polymer mounting system of the silencer has been replaced by two welded aluminum brackets for additional weight savings.
 
E-STARTER
The KTM 150 EXC TPI is fitted with a unique E-starter as standard, a clear advantage when it comes to crunch time in the heat of battle. A bigger and stronger starter motor – power increased from 150 to 350 W – and the proven KTM starter drive ensure efficient and reliable starting at all times.
 
CYLINDER
The compact new cylinder has a sophisticated power valve unit that incorporates a mechanism for the lateral support exhaust ports. Timings have been optimized for the new TPI system and the upper edge of the exhaust port is accurately CNC milled. Two lateral domes hold the fuel injectors that are aimed into the rear transfer ports. This downstream injection guarantees excellent atomization of the fuel for efficient combustion and minimal loss of unburned fuel. The design is the key to outstanding performance across the entire power band with significantly increased torque. The new 2-piece cylinder head has a combustion chamber insert with optimized geometry and is now fitted with a coolant temperature sensor to feed data to the TPI system.
 
TRANSMISSION
The new KTM 150 EXC TPI has a strong 6-speed transmission with gear ratios optimized for enduro riding and adapted to the 150cc engine's power delivery. The gears are supplied by Pankl Racing Systems, and thanks to the newly built transmission production plant, quality and durability have reached a new level. Instead of a circlip, the secondary drive pinion is now retained by a screw and diaphragm spring as is the case on all other KTM offroad models to provide even greater reliability.
 
CLUTCH
The KTM 150 EXC TPI is fitted with a DS (diaphragm steel) clutch featuring a clutch basket that doubles as the primary gear. It is milled from a single piece of high-strength billet steel, a compact, rivetless design to guarantee unbeatable reliability. Heat-resistant friction discs with steel carriers ensure perfect clutch separation. They are pre-tensioned by a diaphragm spring, substantially reducing the actuating force of the hydraulic Brembo clutch action.
 
THROTTLE BODY
All EXC TPI engines are fitted with a new 39 mm throttle body made by Dell'Orto. Power is controlled by a butterfly valve via a twin-cable throttle assembly on the handlebar, with intake airflow data provided by a throttle position sensor. The reworked idle system allows a more precise idle speed setting via the bypass screw, while an enhanced cold start system supplies extra air when opening the bypass. Oil supplied by the electronically controlled oil pump via an oil intake tube is mixed with the incoming air to lubricate the moving engine parts.
 
ALTERNATOR
To accommodate the power requirements of the electronic engine management system and fuel injection, the new KTM 150 EXC TPI has a more powerful alternator than its carbureted predecessor. It is rated at 196 W with a matching regulator, the same as on the EXC-F 4-stroke models.
