I highly recommend Steve Temple, True Tune for servicing and repairs. In 2003, I had the first ST1300 registered in QLD from Pro Honda at Rocklea. Steve was the Workshop Manager there and also services the big Hondas. Many years ago he opened his own shop at 161/B49 Station Rd, Yeerongpilly [gate 2, past World Gym on opposite side to Gym.].
Steve has always been the one to do the work on my second (2008) ST1300 and I totally trust him and his work. He can be contacted on 0409 980 086. See also
