In the two-stroke enduro range, the TE 150i is now fuel injected, utilizing the same Transfer Port Injection (TPI) technology as the two larger-displacement two-stroke models. Those bikes, the TE 250i and TE 300i, have updated cylinders with the exhaust port window now being fully machined, while a new water-pump casing optimizes coolant flow. The engines are also mounted one degree lower for improved front end traction and feel. The header pipes are 1 inch (25mm) narrower and offer more ground clearance, making them less susceptible to damage, and a new corrugated surface helps make the header pipe more durable as well. The two-stroke mufflers feature a new aluminum mounting bracket with different internals and less dense packaging material for more efficient noise damping and a claimed weight savings of 7.1 ounces (200 grams).
