THE PERFECT MIX
The success of the 350 EXC-F has certainly made waves in the industry. Gaining instant recognition on its arrival in 2012, it has become the best-selling 4-stoke competition model ever due to its 250-like agility and 450-like power. Ever since then, and most notably for 2020, the 350 EXC-F has gained significantly in the performance and torque, as well as handling and agility.
