In 1978, nine months after the 400T was launched, Honda followed with a multitude of changes, mainly to the styling, which turned T to N, Dream into Super Dream. 'Eurostyling' was the name given for the
new look, which chiefly entailed a longer, slimmer line for the tank, running down to supportive rear-end treatment. Silencers of more gentle taper, but set at a steeper angle, and new paintwork contributed to the appearance of what was generally acknowledged to be a very handsome motorcycle.

Practical differences from the N series included twin 9.5in front discs, a six-speed gearbox, heavier front-fork springs and improved support for the rear-fork pivot. Modifications to valve timing and carburation were claimed to give greater performance.
