The lamella stops fixed by 2 cruciform screws (easily removable) are specially studied / drilled to avoid gas masses. A small concentrate of special performance technology for your motorcycle. Mounts on mécaboite engine derbi euro 1, 2 and 3. These valves will therefore offer you much more performance than the original models.
