Unveiled in 1991 at the 29th Tokyo Motor Show as a 400 cc version of the CB1000 Super Four, the motorcycle was introduced in Japan for the 1992 model year, with an engine similar to that of the early CB-1.

1994:[3] Updates to the ignition timing due to adoption of the pent-roof combustion chamber design, the internal structure of the muffler, and the shape of the cam chain links for reduced mechanical noise.

A new instrument cluster appeared with the analogue fuel gauge moved to a central location from previously within the tachometer face, a row of indicator LEDs below the clocks, and a hazard light switch.

A special edition Super Four version R model offered PGM-IG programmed ignition timing along with electronic controlled valve operation, in addition to a headlight cowl, sharper rake angle, lightweight aluminium muffler, stiffer suspension and sintered brake pads.

This technique improved the engine's low and mid-range power and efficiency, while retaining performance over 6,750 rpm by resuming four valve operation.

A new lower seat with single grab rail instead of surface belt, light rear brake caliper and updated front suspension offer better ergonomics.

2006:[12] Larger ignition coils supply a more stable spark at lower rpms; clear smoke lenses on the turn indicator lights.

Independent cylinder ignition timing map, revised air intake geometry and a larger stainless steel muffler contribute to fuel efficiency.

Genuine accessories available from Honda include a rear carrier storage box that installs in place of the dual grab rails, a 12V power socket that plugs into the wiring harness, and a central stand.

2018:[15] 25th anniversary model of Honda's PROJECT BIG 1 (SuperFour since 1992), smaller 2-chamber muffler and updated throttle bodies to comply with emissions regulations, also increased the maximum power to 41 kW (55 hp).

LED headlight, updated front and rear suspension, right-angle tyre valve stems, and push type helmet lock bracket.
