Triumph TF 450-E 2026

The TF 450-E presents itself as a powerful but easily controllable enduro bike that also impresses experienced riders. The smooth mapping in particular makes it controllable even for less experienced riders. The chassis offers stability combined with good manoeuvrability. However, the suspension - especially the fork - is somewhat soft, which can reach its limits in rough sections. Yet it delivers a strong overall package with classy features and a professional appearance.

Very easy to control, powerful motor

Good ergonomics for different body sizes

Elegant components and LED lighting

Two mapping options + traction control

Standard enduro bike set-up incl. 18" rear wheel

Fork tuning a little too soft for a sporty enduro bike

Quickshift function not always reliable under full load

High list price (but reasonable considering the features)
