Triumph TF 250/450 X/E VRD velocity stack

VRD Motorsport Velocity Stack

Triumph TF 250 / 450 X & E (2024–2026)

Designed and tested to deliver real performance gains on track, the VRD Motorsport Velocity Stack significantly improves rideability and throttle connection in the low and mid RPM range, without giving up any top-end power.

By optimising intake air speed and flow stability, this velocity stack gives the engine a stronger, more controllable pull off the bottom and through the midrange—exactly where motocross and enduro riders demand it most. The result is a bike that’s easier to ride fast, hooks up better, and feels more responsive under load.

Manufactured from carbon fibre–infused nylon, the VRD stack is built to survive extreme heat, fuel vapour exposure, and vibration in race conditions, while remaining lightweight and dimensionally stable.

This is a direct replacement for the OEM velocity stack, making installation quick and simple with no permanent modifications required.
