Red Bull KTM 250 star and world championship leader Mika Kallio found himself in an unusual eleventh spot in qualifying for the Dutch TT and is still chasing the best set-up for Saturday's GP. The 25-year-old Finn, winner of the British Grand Prix one week ago, found the set-up requirements of the Assen circuit with its high grip level and its banked corners completely different to the English Donington Park raceway. Kallio kept comparing two chassis versions and numerous set-up solutions, but also lost valuable track-time due to the changing weather conditions. He will try further modifications in the warm-up practice session Saturday morning.
