In the modern world a 125 has to be a multi-faceted machine, capable of being the most economical way of getting from A to B, as well as being durable, easy to live with and economical. But it also most riders’ first bike, meaning that it needs to deliver excitement, inspire confidence, and have enough style and credibility to mean that you don’t park round the corner from the pub.

It’s a tough gig, but the 2015 CB125F aims to build on the talents of the current model, and gets a stronger family resemblance, to the CB500F and CB650F, to boost its presence. Honda insist that that the CB has had a decent hike in quality, too, underlying the fact by stating that it’s “been built to endure the rigours of European weather.”

The newly designed steel frame suspends the engine from a sturdy central spine and features geometry that provides the best balance between ride comfort and straight line stability, with a focus toward light steering input and sporty feel at all lean angles. The wheelbase is a short 1292mm, while it weighs 129kg ready to ride.
The twin rear shocks offer 5-step spring preload adjustment, while the fork is non-adjustable. Also new are the six-spoke 18-inch aluminium wheels, which should offer a good balance of stability and ride quality over rough city streets.


The 124.7cc, air-cooled fuel-injected OHC 2-valve engine gets a revised cylinder head for 2015, and the addition of a balancer shaft to keep vibration down to a minimum. The 10.5bhp, 7.5lbft torque, output is delivered by via a 5-speed gearbox, with the balance aimed at strong low and mid-range torque, rather than peak power. Honda claim the engine’s pick up and throttle response is noticeably stronger from the new bike.

The fuel economy will please those averse to opening their wallet too often, with a claimed 120.7mpg providing a range of over 370 miles between fill-ups from the 13-litre tank, helped by its use of the latest PGM-FI system.
