Chassis and handling

The frame of the TF 250-X, constructed from high-strength aluminum, aims to provide an optimal balance between lightness and stability.  This design contributes significantly to the impressive power-to-weight ratio of the TF 250-X, making it one of the leading machines in its class, at least that’s how Triumph describes it, without giving exact figures.  The aluminum swingarm ideally complements the chassis by providing excellent traction and stability in demanding riding conditions.  With a wheelbase of 1492mm and a steering head angle of 27.4º, the TF 250-X is designed for maneuverability and precise handling characteristics, making it particularly agile on the race track.

The tank of the TF 250-X holds 7 liters, which offers a balanced ratio between weight and range.  Overall, the chassis of the TF 250-X is designed to create a seamless symbiosis of performance, agility and efficiency, making it an outstanding choice in the motocross segment, if Triumph is to be believed.

The front of the TF 250-X is fitted with a KYB 48mm coil spring fork, which is adjustable in both compression and rebound and offers 310mm of travel.  At the rear there is a KYB coil suspension with similar adjustment options and a spring travel of 305mm.  This guarantees excellent suspension performance in all conditions.

Triumph has opted for a high-quality Brembo system for the brakes.  The front brakes consist of two 24mm pistons and a 260mm disc, while the rear brakes are fitted with a 26mm piston and a 220mm disc.  This combination ensures outstanding braking performance, which is essential for motocross sport.

In addition, the TF 250-X has a final drive ratio of 13/48, which is designed to optimize power transmission from the engine to the rear wheel.
