The North West 200 starts in sunny conditions on Tuesday as Michael Dunlop heads Superbike practice with Alastair Seeley fastest in the Supersport class.
Seeley is aiming to become the all-time race record-holder at the meeting as he aims for the 16th race victory which would see him edge ahead of other joint record-holder Robert Dunlop.
John McGuinness was among a number of riders to go through the speed trap at more than 200 mph in Tuesday's session.
