CB125R

FULL-SIZE EXCITEMENT

From a small bike that’s big on fun.

With an emphasis on minimalism, the more you ride the CB125R, the more your confidence will grow. While its compact size makes it easy to manage, its big bike features ensure it’s the perfect introduction to real-world motorcycling. The all-new, DOHC 4V single-cylinder engine produces an extra 1.2kW and 1.6Nm peak power and torque driving through a slick-changing, six-speed gearbox. Matching the engine upgrade are 41mm Showa SFF-BP USD front forks – a high-quality specification you’ll find on our bigger bikes – that deliver pinpoint control and steering, alongside full-size tyres and radial-mount front brake caliper with Inertial Measurement Unit (IMU) ABS management. If you’re ready to go to the next level, this is it.

Underpinning the CB125R’s minimalism is its tubular and pressed steel construction lattice-style frame, which is unchanged for the 21YM update. The swingarm is manufactured from steel plate, irregularly shaped in cross-section. Both are designed to achieve high longitudinal rigidity and control torsion from wheel deflection without excess rigidity or weight.

The chassis’ core strength is anchored by the pressed steel swingarm pivot plates and swingarm, allowing the frame to deliver agile handling with stability and feedback; rake and trail are set at 24.2°/90.2mm.

A 51.6% front/48.4% rear weight bias provides a positive feel for front-end grip and easy steering which is also helped by the low, 129.8kg wet weight and compact 1342mm wheelbase. Fat bar-style handlebars turn through 40° and the 2.3m turning circle guarantees easy passage in jammed city traffic. Seat height is 816mm.

41mm Showa Separate Function Big Piston (SFF-BP) USD forks are a major upgrade; this is the first time they’ve made an appearance on any 125cc motorcycle. A pressure separation damper in one fork tube and spring mechanism in the other deliver high damper performance and lighter weight. Together with the use of a larger sized piston the result is increased feel, bump absorption and control. The rear monoshock is spring preload adjustable.

The rest of the running gear remains unchanged; a 296mm hubless floating front disc is worked by a radial-mount Nissin 4-piston caliper, the rear 220mm disc a single-piston caliper. Both are modulated by 2-channel ABS. The high specification system works through an IMU (Inertial Measurement Unit) to give precise front to rear distribution of ABS operation depending on the vehicle behaviour.

The 150/60R-17 radial rear tyre is matched to a 110/70R-17 radial front.
