1 mmThis was the right answer

If your motorcycle has an engine over 50 cc, the entire original tread must be visible, with a depth of at least 1 mm in a continuous band across at least three-quarters of the breadth of the tread. However, your tyres are your only contact with the road, so it's recommended that you replace them before they get to this level.
