A catalogue from the golden age of SunTour, packed with timeless, much-loved models and announcing the ‘new’ and fantastically light Cyclone Mark-II.

But the marketing chaos caused by a company run by engineers is already evident, the Cyclone Mark-II is launched but the old Cyclone lives on, the V GT Luxe coexists with the Vx GT and so on and on.

The capacity table on page 8 is a classic.
