Honda's CBX125F replaced the CB125JX with a high-revving four-valve DOHC single using radial valves and twin carburettors, wrapped in sporty styling with a small cockpit fairing and six-speed gearbox. Revving past 11,000 rpm for its 17 PS, it was one of the livelier learner-legal 125s of the mid-1980s.
