From Honda press release:

When embarking on a two-wheeled career, there are certain fundamentals that every rider looks for from their first motorcycle: an easy-to-ride chassis, with engaging real-world engine performance, and super-agile handling. Wrap those fundamentals, however, in distinctive, classy styling and add a host of premium specifications, and the result can be an extra special machine with which to begin a life on two wheels.

It was for new riders looking for this kind of package that Honda introduced the all-new CB125R in 2017. The smallest member of Honda’s minimalist, bare-boned ‘Neo Sports Café’ family, the CB125R was launched alongside the CB300R and the flagship CB1000R, and represented a bold new, premium addition to the ranks of Honda’s entry level machines.

In 21YM the CB125R received a brand-new, 4 valve engine and major front suspension upgrade, keeping it at the head of a competitive field, and at the top of many young riders’ wish list.
For 24YM, the CB125R is compliant with new EURO5+ emissions targets and the addition of an all-new 5in full colour TFT display, all-new switchgear and four new colours heighten the appeal even further.

Model Overview
The attention-grabbing style of the CB125R is a real standout feature among its peers and sets it apart from the homogeneous crowd.

Peppy and fun to rev, the EURO5+ DOHC 4V engine delivers a healthy 11.0kW power with 11.6Nm torque. And 41mm Showa Separate Function Big Piston (SFF-BP) USD forks bring big-bike suspension quality to a small bike. Braking is equally impressive: a 296mm floating front disc is worked by a radial-mount, four-piston calliper with ABS controlled by Inertial Measurement Unit (IMU). For 24YM a new 5in full colour display and new switchgear add further appeal.

The CB125R uses its very own EURO5+ compliant 125cc, DOHC 4V engine design which produces 11.0kW @ 10,000rpm and 11.6Nm @ 8,000rpm. Top speed is 105km/h, with 0-200m covered in 11.3s. The gearbox is six-speed.

The 24YM CB125R features a new, catalyser in the exhaust system, with no loss in performance.
Bore and stroke is set at 57.3 x 48.4mm, with compression ratio of 11.3:1. PGM-FI fuel injection feeds cleanly through the inlet duct, air cleaner connector tube and resonator. The exhaust is underslung and exits through a dual-chamber muffler.

The new EURO5+ emissions targets, which will become a legal requirement at the end of 2024, sees the introduction of new ‘on-board’ monitoring of the catalyst, the lowering of the threshold for identifying a fault and therefore warning the owner earlier, stricter noise restrictions and improving long-term exhaust emissions.

• 41mm Showa’s Separate Function Big Piston (SFF-BP) USD forks
• Radial-mount 4-piston caliper and hubless 296mm floating front disc
• ABS works through Inertial Measurement Unit (IMU)

Underpinning the CB125R’s minimalism is its tubular and pressed steel construction lattice-style frame. 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 51.5% front/48.5% rear weight bias provides a positive feel for front-end grip and easy steering which is also helped by the low, 130kg wet weight and compact 1345mm 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 use 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 non-adjustable.

The rest of the running gear comprises a 296mm hubless floating front disc, gripped by a radial-mount Nissin four-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. A 150/60R-17 radial rear tyre is matched to a 110/70R-17 radial front.

Styling & equipment
• New 5in full colour TFT meter inherited from CB1000R
• New left switchgear

• Industrial minimal styling with four new colours and new ‘big logo’ graphics for a bold visual impact
• Full LED lighting
• 10.1L fuel tank gives 460km range

The CB125R’s styling is unique to the machine, following the unmistakeable ‘Neo Sports Café’ design language of the CB1000R – minimalist retro styling with a very modern twist – and injects a harder-edged attitude to Honda’s entry level range. For 24YM, this styling has been enhanced with the addition of an all new 5in full colour high-visibility TFT screen inherited from the CB1000R. The screen offers three types of speed/rpm display – analogue or bar, according to rider preference – as well as fuel gauge/consumption, gear selected and customisable shift-up point on the rev-counter.

Management is via the new left switchgear, which is both stylish and intuitive.

The cutaway tail unit is compact in the extreme and holds the rear mudguard mount. Both rider and pillion footpeg hangers are aluminium.

Full LED lighting – including indicators – adds a further premium feel and contributes to mass centralisation. The headlight uses a dual bar light signature, upper for low beam and lower for high beam and the taillight remains thin and stylish.

The 10.1L fuel tank is hidden underneath an angular cover and shrouds and houses an aircraft-style filler cap. With fuel economy of 45.5km/l (WMTC mode), the CB125R can cover over 460km from full.
The 24YM CB125R features colour matched big CB125R logos on the radiator shrouds, and negative coloured Honda Wing logos on the tank. The only exception is the Matt Cynos Gray Metallic colour scheme, which is unique in the line-up, with gold CB125R and Honda Wing logo on shrouds and tank respectively.

A full range of genuine Honda accessories are available for the CB125R and include:
• 5 stage heated grips with memory function
• 15L rear seat bag, expandable to 22L, complete with rain cover
• 12V ACC socket
