Updated: February 11, 2026

Triumph has unveiled several new dirt bikes in the past few years, and it all started with the TF 250-X in 2024.

In its third year on the market, the TF 250-X boasts a new airbox, muffler, and Exedy clutch, enhanced engine mapping, a revised battery tray layout, redesigned oil level sight glass, and updated suspension settings.
