Sam Lowes rekindled his strong test form to finish practice on top, both in FP3 and overall when the practice sessions are combined.
Halfway through the session the Gresini man hit the top and chipped away at his time to then post a 1m 59.262s lap, bettering all-comers so far this weekend, while also seeming to solve his crash issues in a smooth consistent session for the Briton.
Until then Tom Luthi had lead the way, the Swiss Interwetten man seemed in much more of an aggressive mode on track, with his time remaining good enough for second in the session.
Lorenzo Baldassarri rode his Forward Racing machine solo for most of the forty minutes, needing no assistance to secure third.
