A feature looking back at the 1978-1982 history of the CBX, Honda's first inline-six-cylinder road bike. Announced in December 1977, the CBX was an export-only model whose deliveries began in 1978, arriving ahead of the concurrently developed CB900F. The piece traces its footprint, including a press ride event held at the Suzuka Circuit.

It'd be premature to dismiss the choice of an inline-six as mere excess. What the CBX carried was Honda's pride itself, forged from conquering the world with multi-cylinder engines. A machine sent overseas as an export-only model had no small influence on the air-cooled fours that followed. Machines carry the ambition of the era they were born into.

Other makers had multi-cylinder models around the same time, but the CBX must've had a presence on a whole different level.

An inline-six motorcycle is rare even today, and this one's been around for over 40 years.

The bit about the press test ride at Suzuka really conveys how much energy there was back then.

Export-only means it wasn't officially available to buy domestically, I guess.

Right, I heard back then some people got hold of it through reverse imports.

The idea of putting an inline-six in a street bike — for the time, that's an insanely bold move.

Didn't know it actually came out before the CB900F — interesting how they positioned it as an export-only model.

Unveiled in December 1977 with deliveries starting in '78 — that's pretty fast turnaround for the era.
