2019 Honda Monkey Review of Specs & Features | Motorcycle / Mini Bike (Vintage / Retro Styling)

If you follow the blog, you’ve seen where Honda has been playing around with the idea of building a newer version of the old-school Mini Trail / Monkey bike for quite some time with posts dating back to 2016. If I were to guess, I’d say with how hot the Grom / MSX125 sales turned out to be, they couldn’t turn a cold-shoulder to the idea of building this Monkey concept into a production bike as the internet went crazy when they released it as a concept motorcycle. Now if only we can get Honda to build the Grom Scramble Concept One & Grom Scrambler Concept Two we’ll be set – right?

Let’s get back to the topic at hand though as I’m getting sidetracked on other models. The 2019 Monkey 125. It’s a legit thing for 2019 and is coming to the USA more importantly as I mentioned in this post last week stating we were getting an Official USA Release, Click Here. Just a few short months ago, Honda made the announcement that it was going to be released in Europe and other misc countries around the world to many people’s surprise. You can follow the history of the Monkey 125’s story from concept to production and me discussing whether or not it would eventually release in the USA etc by Clicking Here. Getting a bike past that concept phase isn’t easy and can sometimes be a long road or even a road with a big fat dead-end sign to greet you at its end. Customer feedback whether it be at a motorcycle show that Honda attends or online via different social media outlets like FacebookTwitterInstagramYouTube etc can have a huge affect so make sure to voice your opinions when you see something you like. You never know, that next concept bike you fall in love could end up making its way to production.

1. | 2019 Monkey 125 Introduction / History

2019 Honda Monkey Review of Specs & Features | Motorcycle / Mini Bike - 125 cc

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. There, Honda’s 49cc-powered Z100 was featured as part of an attraction designed to help park goers experience the joys of riding. So popular amongst guests of all ages and sizes that the bikes quickly earned the nickname of “Monkey,” a term originating from how the larger riders looked while riding around. So popular was the attraction that, in 1964, Honda began producing a street-legal version called the CZ100, for European and Asian countries. The craze had started, and it wasn’t long until America would get its first taste of how much fun a mini bike can be.

Waiting is the hardest part, but America’s delay for a true Honda mini bike ended in 1968, when the first Z50A was made available in the U.S., complete with 8-inch wheels, knobby tires, adjustable seat, and loveable styling. The best part? A folding handlebar meant parents could stow the bike in the trunk of a car and drive their children to the local riding spot—and probably even go for a ride themselves. Memories were being made, one ride at a time.

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.

Outfitted with a headlight and taillight, the 1969-1970 Z50A served as Honda’s quick adjustment to the widespread popularity of the model and opened the door to a wider range of riding. The trend continued, each Z50A being tweaked to fit the needs of its growing fanbase, and in the process, capturing the hearts of Americans. Fun, accessible mobility, through a likable design, tiny dimensions, and low weight, had caught on.

The Z50A’s design continued to evolve with features such as dual rear shocks, introduced in 1972.

From there, Honda’s North America-bound Z50A models evolved into machines bred for off-road riding, while Europe’s Z50J carried the torch as a fun machine for getting around town. But already, the Z50 and its Monkey namesake, had been cemented in millions of hearts by giving countless riders their first experience of twisting the throttle on a powered two-wheeler.

By 1978 – a point that marked the start of real prime time for the Monkey – the machine 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, minuscule 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.

Today, the desire for an easy-to-handle motorcycle that puts a smile on not only the person riding it, but even those who aren’t, is alive and well, as evidenced by the success of Honda’s Grom. A master of fun, the 2019 Honda Monkey builds on that passion just like the Grom has the last few years, while celebrating the Z50A models that paved the way for so many riders through the 1960s and ’70s, and opening the door to the next generation of enthusiasts.

After the modern-day success of the sharp-suited Grom / MSX125, which proved the desire for a funky, pocket-sized town run-around, it was time for the Monkey name to return, reborn and ready for life in the 21st century city.

Naturally the classic Monkey style had to provide the cues for the new model. A trapezoid silhouette highlights the compact length, while adding depth and substance to its stance. Simple, curved surfaces are designed independently of each other and feature throughout.

The glossy 1.5 gal. fuel tank, finished in the same paint color as the frame, swing arm and rear shocks, crowns the machine, and proudly wears a historical 3-D Old Wing design Honda logo. Chromed steel high-level front and rear mudguards – plus the evocatively-stamped exhaust shield, circular mirrors and high-rise handlebars – all pay homage to the original.

Modern technology is fully present within the evocative reincarnation of the classic look: 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 Old Wing motif) features an ‘answer back’ system that makes the lights flash at the push of a button to allow easy location in crowded car parks; the single channel ABS system operates with an IMU to mitigate rear ‘lift’ under strong braking.

As for the Monkey’s engine, true to its origins, the Monkey’s horizontal SOHC 125cc single-cylinder engine is simple, robust and tuned to deliver useful about-town performance. Air-cooled, with bore and stroke of 52.4 x 57.9mm and compression ratio of 9.3:1, fed by PGM-FI, it produces 9 horsepower @ 7,000rpm and 8.1 lb/ft of torque @ 5,250rpm. The gearbox is 4-speed and the engine returns fuel economy exceeding 130 MPG.

Compared to the Honda Grom, the Monkey shares more of the same engine details than what are actually different. They are identical in bore and stroke as well as compression ratio. The Grom makes less than one more horsepower and there is only about .1 of a difference when it comes to their torque numbers but max torque comes in about 250 RPM sooner whereas their peak horsepower figures both come in at 7,000 RPM. I haven’t been given the gear ratio numbers yet but I would almost bet money that they are identical as well as sprocket counts up front and in the rear. The Monkey does come in at about 10 more pounds but that is only if you’re comparing it to a non ABS model Grom, if you compare apples to apples and ABS versus ABS model then it’s less than a full pound of difference. Long story short, if you’re wanting to know how the Monkey 125 VS Grom 125 race would turn out… I would say that the guy winning that race would be whoever had the lighter breakfast that morning and has more skills than the next guy. The nitty-gritty performance details and specs when comparing the Monkey versus Grom are just too similar for there to be a clear winner.

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

Wheelbase is set at 45.5 in., while rake and trail are set at 25°/82mm for confidence-inspiring handling and a minimum turning radius of just 6.2 ft. Wet weight is a mere 235 pounds with a tank full of gas and all fluids, with a seat height of 30.5 inches. The plush seat is made of high-density urethane for maximum comfort.

The inverted USD front forks wear a premium Alumite finish and are matched by dual rear shocks with 4 inches of suspension travel. Maximum ground clearance is 6.3 inches. A single 220mm front disc and 190mm rear provide secure stopping performance, and on the ABS Monkey, braking up front is managed by the IMU-based ABS. Fat 12-inch block pattern tires make for a smooth ride and are sized 120/80-12 65J front and 130/80-12 69J rear.

What do you guys think about the USA finally getting the Monkey 125 motorcycle for 2019?

Personally, I’m beyond excited! I need one of them about like I need another hole in my head but I would love to park one of these next to my Grom and in a few more years be able to mob around town with my son on these mini bikes. If you would have asked me prior to the Grom being released in 2013 if I would ever be excited about the idea of a 125cc motorcycle… I would have told you that you’re clinically insane. There’s just no way but after decades of riding and track days etc and chasing more speed and more horsepower etc, it’s nice to just ride a 125cc bike for what it was meant for and that I can be 100% throttle almost all of the time and not have to worry about a cop seeing me and the end outcome be me locked up on a jail-cell for the night haha. It’s hard to look at these bikes, whether it be the Monkey or the Grom and not just smile from ear-to-ear thinking about all of the fun you could have bringing out your inner hooligan / child again. You can commute on them and get 130+ MPG while still being able to pull highway speeds, you can turn any parking lot into a racetrack by yourself or with a group of friends as once you get one of these bikes – it’s easy to coax your friends into the purchase too after letting them ride it. I can speak from experience on that one! All of my buddies thought I was crazy when I told them I was getting one of the first Groms to hit the USA back in 2013 as we all ride big sport bikes etc. That kind of talk went out the window real quick though once they saw me riding it and took my Grom for a spin to see what it was all about… Next thing I know, I’ve got probably 15-20 friends that bought a Grom so we could all mob around town together and have some fun. My ribs were usually hurting at the end of the day from laughing so hard. It’s amazing just how much more fun we have when we’re on our Groms than when we’re on our big bikes – there’s just no comparison.
