Honda Super Cub C125 C125A 2018-2021 Service Manual

MCN's own review captures the genuine significance of this bike's late-2018 return: "the charming Honda Super Cub 125 is a digitally remastered version of the much-loved classic, fit for the 21st century... its late 2018 launch marked the first time a Cub had been imported to the UK for years." TotalMotorcycle's own retrospective traces the original bloodline back to Honda's own transformative moment: the first Super Cub C100 rolled off the production line in 1958, crossing the Pacific the following year to launch American Honda Motor Company itself — the C125 is styled directly after that original 1958 machine's silhouette rather than the more familiar 1970s-era Cubs many riders remember.

Power comes from a 124.9cc air-cooled SOHC single-cylinder four-stroke, two valves, an 80-degree cylinder angle, a 52.4mm x 57.9mm bore and stroke, and a 9.3:1 compression ratio, fed by PGM-FI fuel injection with automatic enrichment — genuinely the largest engine ever fitted to a Cub, per MCN's own review, run through a 4-speed semi-automatic transmission rather than the classic three-speed used on smaller-displacement Cubs. WebBikeWorld's own feature breakdown explains the genuinely unique shifting mechanism: "you shift with your left foot, like a traditional motorcycle. But here's the unique feature: there's no clutch to worry about—you just toe and go" — a real hybrid between manual and automatic operation that's defined the Super Cub name since its inception.

MCN's own review notes genuinely modern touches layered onto the classic silhouette: cast wheels replacing the old wire-spoke design, a digital dash, and keyless ignition — while WebBikeWorld's own coverage confirms the telescopic front fork, though partially faired to visually echo the original leading-link design, "works a lot better" than that vintage setup while still preserving the classic dual rear shocks and step-through frontal bodywork that shields riders from wind and road splash. Standard equipment includes a 220mm front disc brake with standard front-wheel ABS, tubeless tires, and a genuinely accessible 30.7-inch seat height that lets most riders flat-foot at stops. MCN's own review notes a real trade-off versus modern scooters: "there's no underseat storage and no room for a pillion" — genuine practicality sacrificed for authentic period styling. The C125 won Best Scooter at the 2019 MCN Awards, and this platform ran with minimal changes through 2021 before continuing largely unchanged in subsequent model years, a testament to how thoroughly Honda got the reintroduction right on the first attempt.
