Kellerman Atto Indicator

The Kellermann Atto® is the ultimate choice for Triumph riders aiming for a clean, classic rear end without sacrificing visibility or safety. At just a few millimetres across, it’s the smallest ECE-approved indicator available—almost invisible when off, yet intensely bright when in use.

Ideal for modern classic builds where minimalism is key, the Atto® blends effortlessly into the lines of your Bonneville, Thruxton, Scrambler, or Speed Twin, allowing you to strip back your bike’s lighting while staying road legal.
