ENGINE & EXHAUST

Engine

Thanks to state-of-the-art engineering, innovative 2-stroke design, and revolutionary TPI fuel injection technology, the 150 cc 2-stroke powerplant is as surprising as it is effective. Delivering class-leading power throughout the entire rev range, the benefit to this compact, lightweight 2-stroke is down to its approachable rideability, making it a great option for those looking to delve into more extreme action, without the intimidation of a bigger 2-stroke.

Cylinder

The KTM 150 EXC cylinder has a bore of 58 mm and with refined port timings and the aid of a sophisticated power valve, provides really smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes which hold the fuel injectors that supply fuel to the rear transfer ports. The downstream injection guarantees excellent atomization of the fuel with the upstreaming air. Thus, the loss of unburnt fuel is minimal, resulting in less emissions, a more efficient combustion and reduced fuel consumption. A small tube in the back of the cylinder is connected with an intake pressure sensor, which supplies pressure data to the control unit. The cylinder features a power valve unit with a sophisticated mechanism for the lateral support exhaust ports. The exhaust port layout increases engine performance, while the upper contour of the exhaust port has been machined to ensure more accurate port timing. The new cylinder, with TPI technology, produces outstanding performance over the entire range with significantly increased torque compared to its predecessor.

CHASSIS

Frame

All KTM EXC models feature high-tech, lightweight Chromoly steel frames with race-derived geometry, optimal stiffness, and unparalleled feedback for the rider. This translates into a playful handling character, with remarkable stability at speed - not to mention FACTORY RACING style thanks to the striking orange coating. The subframe is made of extra-light and ultra-stable aluminum profiles, weighing less than 900 grams providing rear fender stability and durability in the event of a loop out.

Swingarm

The KTM 150 EXC features a one-piece aluminum swingarm, which is manufactured using a gravity die-cast production process. This results in exeptional strength at the lowest possible weight and the perfect flex b
