One think that got me with the Mk2 Super 8 was despite the really chunky tubes and the girder like construction of the swingarm, how the dropouts were only held on with little allen keys bolts.  I was really impressed with all the bracing etc on the swingarm, no idea how they managed to develop cracks.  They must have been one of the first to use a wider and oversized rear axle were they?  142 x 10?
