There are several threads on the board about aftermarket gauges - and there are several vendors. As far as directly compatible OEM sets, I haven't heard of any. One thihe 1G Bandits have a cable driven speedo, so newer bikes (and even some of the same era) won't work since they have electronic speedos. With the tach, the redline on the face isn't likely to be at the same spot as the Bandit - that isn't even the same between the 600 & 1200.
