New 2023 Honda Monkey 125 Colors

2023 Honda Monkey 125 Review / Specs | Banana Yellow

1. | 2023 Honda Monkey Introduction

The Honda Monkey bike is perhaps most widely known as a groovy icon of the 1970s, but it first saw the light of day in 1961. Originally developed as a 49cc child’s plaything for Tama Tech, an amusement park in Tokyo, it proved so popular that a road-going version was developed, which was initially exported to America and Europe in 1963, with a distinctive chrome tank, folding handlebars and 5-inch diameter rigidly-mounted wheels.

Its popularity was based on a cute, instantly-likable design, tiny dimensions and ultra-light weight – which made it a whole load of fun around town. By 1969 its wheels had increased to 8-inch in diameter and from 1970 it gained even greater popularity, when the addition of quick-detach forks meant it would fit into the trunk of a small car.

By 1978 – a point that marked the start of real prime time for the Monkey – the bike had been re-styled with a teardrop style fuel tank, and became hugely popular with legions of RV (Recreational Vehicle) drivers in need of convenient transport to use once they were parked up. And this is where and when the cheeky Monkey really cemented its place in millions of hearts; with its 3-speed gearbox and centrifugal clutch (which needed no ‘traditional’ motorcycle skill to operate) it gave thousands of riders their first experience of twisting the throttle on a powered two wheeler.

Because it was so much fun, and so easy to ride, it did more to sell the concept of motorcycles to a wider public than perhaps any other machine. With its chunky tires, mini-‘ape’ style handlebars, miniscule fuel tank and big, squashy seat the Monkey look is unmistakably of its time, but – just like the affection in which it is held – also timeless.


And in 2018 (2019 for the USA) the Monkey’s time came around once again. Inspired by the original (but also as a usefully fun 125cc motorcycle fit for the 21st century) a brand-new Monkey cheered up the roads. For 2022 the Monkey got an engine upgrade, an extra gear for the transmission, suspension refinements and detail improvements, widening its ‘smile’ factor and building-in extra day-to-day usability.

Nothing changes mechanically for the 2023 Monkey 125 but three brand-new, ultra-retro paint options mean that pocket-sized Monkey fun has never looked so good.

2. | 2023 Honda Monkey Overview

Drawn from the MSX125, also known as the Grom 125, the Monkey’s two-valve air-cooled engine produces 9.25 horsepower (6.9kW) with 8.11 ft/lb torque (11Nm). It’s durable and easy to use while a 5-speed gearbox opens up longer rides. The steel frame, USD forks, twin rear shocks and 12-inch wheels roll smoothly; for extra safety the ABS braking is Inertial Measurement Unit (IMU) controlled.

2023 Honda Monkey 125 Review / Specs: Colors

Then, of course, there’s the inimitable Monkey look, correct from the mini-ape ’bars to upswept exhaust. For 2023 the Monkey pays proper homage to the 1967 version, with its checkered seat pattern and classic Honda style of the time. 

3. | 2023 Honda Monkey Key Features

3.1 | 2023 Honda Monkey Chassis & Styling

  • Steel frame, inverted forks and 12-inch diameter tires
  • Twin rear shocks feature two-stage springs to deal with rough surfaces
  • Curb weight of 229 lbs with ABS, with wheelbase of 45.1 in. and 30.5 inch seat height
  • Classic Monkey style continues – a timeless statement of individuality
  • Rear carrier available as an official accessory

The Monkey’s steel backbone frame is tuned for a suitable balance between rigidity and supple feel – perfect for the wide variety of conditions the machine is designed to be ridden in. Oval in cross-section, the swingarm echoes the circular design theme that runs through the bike.

2023 Honda Monkey 125 Review / Specs: Suspension

USD front forks employ 3.94 inches of travel (100mm) and wear a premium Alumite finish. The dual rear shocks now feature two-stage springs and revised damper rubbers, for improved ride quality on bumper roads and reduced bottoming. They have 4.02 inches of axle travel (102mm); maximum ground clearance is 6.9 inches (175mm).


2023 Honda Monkey 125 Review / Specs: Suspension

A single 220mm front disc and 190mm rear provide secure stopping performance, managed by the IMU-based ABS. Fat, block pattern tyres make for a smooth ride and are sized 120/80-12 65J front and 130/80-12 69J rear.

2022 Honda Monkey 125 Review, Specs, New Changes Explained + USA Information | 125cc Motorcycle / Mini Bike | miniMOTO Vintage / Retro Bike

Wheelbase is set at 45.1 in. (1,145mm) with rake and trail of 25°/3.2 in. (82mm) and a minimum turning radius of just 6.2 feet (1.9m). Curb weight is 229 lbs (104kg) for the ABS model, with a seat height of 30.5 inches (775mm). The plush seat is made of high-density urethane for maximum comfort.

Classic Monkey style (mini-ape handlebars, chromed mudguards, upswept exhaust with stamped heat shield, chunky tires, padded seat and ‘peanut’ tank) pays loyal homage to the original and provides all the cues required to chime both with those of a certain age, and a much younger generation.

2022 Honda Monkey 125 Review, Specs, New Changes Explained + USA Information | 125cc Motorcycle / Mini Bike | miniMOTO Vintage / Retro Bike

Older riders connect to a certain ‘70s irreverence – maybe matched to a memory of their first feel of motorcycling freedom – innate in the design while newer riders, already turned on to all things retro, get both that and something undeniably funky to set them apart from their friends. One thing that unites everybody, whether riding a Monkey or simply passing one by, is the ‘smile’ factor. It’s that sort of bike.

For 2023 a fittingly stylish tubular steel rear carrier is available as an official accessory – usefully suitable for heavier loads of up to 6.6 lbs (3.0kg). The glossy 1.5 gallon fuel tank (5.6L), which are finished in different paint schemes than the rest of the bike this year, swing arm and rear shocks, proudly wears a historical 3-D Classic Wing design Honda logo.

The 2023 Monkey 125 will be available in three color schemes:

  • Banana Yellow with yellow frame, swingarm, rear fork springs, black/white tartan seat and white tank infill
  • Pearl Nebula Red new red frame, swingarm rear fork springs, black/white/red tartan seat and silver tank infill
  • Pearl Shining Black with black frame, swingarm, rear fork springs, black/white tartan seat and white tank infill
    • * USA 2023 Monkey 125 colors: TBA (at the time of writing this)

3.2 | 2023 Honda Monkey Electronics

2022 Honda Monkey 125 Review, Specs, New Changes Explained + USA Information | 125cc Motorcycle / Mini Bike | miniMOTO Vintage / Retro Bike

  • Digital circular LCD gauge display
  • Full LED lighting
  • IMU control reduces rear lift under braking
  • ‘Answer back’ system for easy identification

Modern technology is fully present amongst the classic looks: a digital full-LCD circular meter features speedometer (which winks playfully when the ignition is turned on), odometer with two trip meters and six-segment fuel level indicator; all lighting is LED; the ‘wave’ pattern key (which also wears the Classic Wing motif) features an ‘answer back’ system that makes the lights flash at the push of a button to allow easy location in crowded parking lots; the single channel ABS system operates with an IMU to mitigate rear ‘lift’ under strong braking.

2023 Honda Monkey 125 Review / Specs | Pearl Nebula Red

3.3 | 2023 Honda Monkey Engine

  • 124cc air-cooled engine delivers 9.3 horsepower and 8.1 ft/lb torque
  • 5-speed gearbox for easy cruising speed
  • EURO5 compliance

The Monkey has a 124cc SOHC two-valve air-cooled engine (drawn from the MSX / Grom but tuned differently, with different HP & TQ numbers) with a 50mm bore, 63.1mm stroke and compression ratio of 10:0:1. Peak horsepower for the 2023 Monkey comes in at 9.3 HP @ 6,750 RPM (6.9kW) and 8.1 ft/lbs of torque @ 5,500 RPM (11Nm).

How do those 2023 Monkey 125 performance numbers compare against the 2021 and prior generation Monkey? Pretty much neck and neck! The previous generation had the same ratings from Honda for both horsepower and torque but it’ll feel different as the power comes on differently. Granted, it’s not a massive difference but still. The new 2023 Monkey makes its peak horsepower at 6,750 RPM whereas the old Monkey came in at 7,000 RPM. However, you can flip that when it comes to their torque numbers on the Monkey. The new 2023 Monkey’s peak torque comes in at 5,500 RPM whereas the old Monkey was at 5,250 RPM. It’s not massive, but still a difference nonetheless.

A correcting plate manages the path of fresh air drawn in and feeds an intake duct inlet and connecting tube designed to smooth airflow. The shape of the airbox also promotes smooth airflow, smooth torque output and flexible drivability. For EURO5 compliance a compact catalyzer deals with spent gasses efficiently; the exhaust downpipe length is optimized to the intake side, while the muffler uses a one-chamber design for efficient performance and characterful exhaust note.

The 5-speed gearbox, replacing the older 4-speed in 2022, spreads the gear ratios further apart to improve longer journey performance and provide a more relaxed cruising ability. Honda claims the 2023 Monkey 125 top speed is 56.5 MPH (91km/h). Manual clutch operation imparts a full-sized motorcycle experience while 12-inch wheels deliver agile around-town response. Naturally, the Monkey’s small stature and assured low-speed balance allow it an easy passage through jammed traffic.

It’s also an economical engine, returning 156 miles per gallon (1.5 liters/100km WMTC mode) by using low-friction technologies, such as an offset cylinder and roller-rocker arm for the valve gear. Sophisticated PGM-FI guarantees highly efficient combustion.
