The engine of the 150 SX is well-known as the most powerful and most competitive engine of the class. However, it is time to give a new push to the segment and set a clear statement that two-stroke technology is going to have a successful future due to its outstanding power-to-weight ratio, low cost and simplicity. The newly developed 150 cm³ engine for MY 2016 features a completely new architecture with the latest know-how and state-of-the-art technology. The result is that it produces better power all over the rev range, it’s more than 2 kg lighter than the predecessor and it is much more compact.
CYLINDER
Within the heart of the new engine is a newly designed cylinder with reworked ports and a newly developed power valve unit with a sophisticated mechanism for the lateral support exhaust ports. Together with a new two-component cylinder head, a massive performance increase over the entire range has been achieved. Even though it is 0.8 lb lighter and more compact than the previous model, the new layout of the water jackets in the cylinder and head guarantee a better heat dissipation, keeping the 150 SX cool under the most extreme conditions.
DIE-CAST ENGINE CASES
For the latest 2-Stroke engine generation the KTM engineers designed all new die-cast engine cases featuring a 27 mm higher clutch shaft and 37 mm higher crankshaft position, which results in better mass centralization for improved rideability. In addition, the engine itself is much more compact and this contributes massively to the weight reduction of 1.3 lbs.

But it was time to give a new push to the segment and set a clear statement, that 2-Stroke technology is going to have a successful future due to its outstanding power-to-weight ratio, low cost and simplicity. The newly developed 150 cc engine for 2016 features a completely new architecture with the latest know-how and state-of-the-art technology. The result is an engine that produces better power all over the rev range, is 4.4 lbs lighter than the predecessor and is much more compact.

EXHAUST
For the new model our engineers developed a new, specifically tuned exhaust pipe in order to get the maximum power output of the engine.
