Following their World championship race at Donington Park Ben and Tom Birchall headed directly over to the Isle of Man to prepare for their TT campaign.
The first practice session was on Monday evening and with the sun low in the sky (see photo) it made conditions difficult.
But the Mansfield brothers set off to complete two laps of the 37.73-mile mountain roads course posting the second fastest time of the session in a time of 20m 29.143s – an average speed of 110.508mph.
Ben and Tom will be back in action on the Hanni LCR/Cofain Racing by Klaffi F2 outfit again tonight (Tuesday) for a further practice session weather permitting.
