The 2025 KTM 85 SX packs fresh firepower and gives an updated engine to starting gate. Weighing 120 grams less than the previous generation, the updated engine produces higher performance and optimised integration with the chassis updates. This means more punch in the low and mid-RPM range, more torque, and improved reliability.
