The 2022 Honda Monkey Bike is here, with a new five-speed gearbox and an engine that conforms to Euro5 emissions regulations. We've yet to ride that version, though, so in this review we're dealing with the 2018-2021 version instead.

Honda produced the very first production Monkey bike back in 1967 and the new model continues the spirit of the original.

The frame and engine are from Honda's MSX125 minibike as introduced in 2014, which also donates its wheels, brakes and front suspension, but the styling is very much inspired by the original, with the result being mouth-wateringly cute but with thoroughly modern mechanicals and manners.

Size-wise we’re talking small – the new Monkey has 12in wheels and a seat height of only 776mm. But the biggest compliment we can give the Monkey is that it works just like any other modern 125: it’s hugely enjoyable to ride, able to keep with – and cut up – traffic with ease, with the result that for riding around town, it’s quite simply brilliant.

It’s so small, light and nimble that it slips through traffic but unlike other dreary commuting bikes, is a laugh a minute.

On faster roads, such as country A-roads, with a top whack of around 60 and a sense of vulnerability that goes with its size, it’s a different story of course – and we wouldn’t recommend the Monkey for dual carriageways or motorways, either.

But that’s missing the point. Honda has built a bike that not only looks good but also functions in the modern world. On some retros that isn’t always the case as, frustratingly, styling so often takes priority over ride-ability.

What’s more, as with most 125s, the Monkey can be ridden on L-plates with a provisional driving licence, as long as you've taken a CBT. All of that’s true of the slightly cheaper, arguably funkier Grom, too. But that bike’s more for trendy teens. If you like a touch of classics and want a fun bike that reminds you of your youth we can’t think of any cuter introduction to motorcycling.

The Honda Monkey is a laugh a minute

The biggest compliment you can give the Monkey is that it works just like any other modern 125 – with a sheet chucked over it you’d be hard pressed to tell you were riding something that looks so daft.

Because the Honda Monkey is so small you can simply fly around town – hitting gaps in traffic that aren’t really on before buzzing off into the distance.

The suspension – modern-looking inverted forks at the front with colour-coded, non-adjustable twin shocks at the rear – is set ultra soft, as is the enormous, deeply padded and ribbed seat, but on the rough roads of our London West End test ride, it was my derrière’s best friend, dispatching potholes with ease.

The only downside to this soft ride is that the Monkey has a max permissable weight limit of 105kg, which you could easily reach if you’ve got all your gear on and a bag full of ‘swag’.

MCN's Gibbons rides the Honda Monkey

At the other extreme, you could also take the Monkey on a motorway – not that we would recommend it. It’d be utterly tedious not to mention making you feel slightly paranoid. Realistically, the Monkey is a bike designed for urban living, something it demonstrated by making light work of a heavily-congested Stratford near the Olympic Park.

Given the Monkey’s so light, the braking is good, too. Although there’s just a single 190mm disc upfront grasped by meagre twin piston caliper with a matching set up at the rear, they’re powerful enough with plenty of feel.

While even the ABS system, which is linked to an IMU to keep the bike level under hard braking, is faultless and the only time I managed to get it activating throughout the day was on some very aggressive traffic-calming bumps.

4 out of 5 (4/5)

Honda’s modern Monkey is powered by an air-cooled, four-stroke 125cc motor producing just 9bhp and 8.1ftlb of torque – although this was uprated for 2021 – and is easy as pie to operate: key in, turn it on and the Monkey's LCD dash bursts into life and gives you a cheeky little wink (no really).

Then you simply stab the starter button, click it into gear and set off on one of the most grin-inducing rides you can imagine. The little Monkey is unbelievably fun.

The little air-cooled single has enough poke to keep things interesting and because it weighs nothing it pulls away quite quickly.

The Honda Monkey is great fun around town

It only has four gears though (although this again was uprated to five for 2021), so it does seem to run out of puff around 55mph – but that's more than enough for inner-city riding wher you also appreciate its ultra-light clutch and feather-light gearbox, meaning that changing ratios takes little effort.

The Monkey's throttle is delightfully smooth too, without any hint of snatchiness at low throttle openings, and is also remarkably vibe-free, except at tickover when it shakes like a miniscule Harley-Davidson.

But while all that’s fine around town and for sitting in flowing traffic, that meagre performance means overtaking is pretty much ruled out. Yes, the Monkey accelerates well and you can outgun cars into roundabouts and up to about 40mph, but even 50mph lorries require a very long stretch of clear road to crawl past.

Although the Monkey, and its stablemate, the MSX125 Grom, aren’t the only monkey or mini bikes currently available on the market – and are certainly not the cheapest, either – both exude an air of class and quality few others come close to.

Although small it’s as properly designed and equipped as any other Honda. The Grom has a good reputation for reliability so there’s no real reason the Monkey shouldn’t develop one, too. Owners also rave about its quality and reliability, it stands out in a crowd and both have also developed a devoted following, reassured by Honda’s quality dealer network and a two year warranty.

With the Monkey, besides the basic MSX mechanicals, all the required classic details are present and correct, including the old-school Honda Wing logo on the tank – but it doesn’t look any the worse for its modern features either. It even exudes an air of old-school Honda quality because all the shiny things are proper metal, not just plastic with a chrome veneer.

The Honda Monkey at The Bike Shed

If looked after, we’ve no reason to expect any problems. The Monkey is a Honda, with all the reassurance and quality that brings. It’s an understressed 125, so is unlikely to suffer wear or strain, and it’s dimuitive and a doddle to ride, so unlikely to suffer crash damage.

Our only slight hesitation comes from any damage or reliability issues that may arise from owner Tomfoolery or neglect – it is a fun 125 after all. Although, on reflection, that’s more likely a doubt to be aimed at the Grom rather than the Monkey, which we suspect will probably be bought by more mature riders.

In our experience, people instantly warmed to the wacky Monkey. From the petrol pump attendant who laughed at its size to the builders on the M40 who filmed the Honda as it crawled past a lorry, everyone reacted positively to it.

Throughout the day we spent together there were so many small moments as people reacted to the diddy Honda that made me smile.

Our Honda Monkey Bike owners' reviews show glowing praise for the tiny tearaway, with no reliability issues reported.

Although not cheap to buy compared to some mini or monkey bikes, the Honda Monkey 125, and its MSX125 Grom sibling, should be as cheap as chips to run.

The only comparable monkey bikes recently available have been WK Bikes Colt 50, which has nothing like the credibility or performance of the Hondas, and Benelli’s TNT 125, which is now deleted, and was more of a budget Grom-rival than an alternative to the Monkey.

Being a 125 means Monkey insurance will be cheap, too, depending where you live of course. Its diminuitive performance means it doesn’t have much of an appetitie for the usual consumables such as tyres, brake pads, chain and so on.

Servicing should be affordable, too, as it’s a doddle to work on and on top of all that Honda claim it does an impressive 189 miles to the gallon!

A further boost will almost certainly be residual values. While cheaper, less desireable monkey bikes will see their value plummet the second you wheel it out of the dealer’s door, both the Monkey and MSX125/Grom are already almost cult bikes and hugelt in demand, meaning residual values are strong – something again assisting cost of ownership.

When launched the Monkey cost £3695, exactly £300 more than the Honda MSX125 Grom that it’s based on but, in our eyes at least, it’s worth it for the extra cool factor alone.

Like all modern manufacturers, it’s also available via a couple of finance options including PCP for around just £65 a month and HP for £100 a month. That said, as we write Honda were also offering the larger Honda CB300R for just £59-a-month, or a Honda CMX500 Rebel cruiser for £89-a-month, which both make the little Monkey look like poor value. But do they offer the same cool factor? Only you can decide.


5 out of 5 (5/5)

This is one of the key areas where the Honda Monkey 125 – and its MSX125/Grom brother – stand out from other mini bikes available on the market.

Amazingly the wee Honda Monkey is full of the latest tech. For a start the little LCD dash features a digital speedo, two trips plus a six bar fuel gauge – all useful stuff – while the little key fob has a button to ‘answer back’ in case you lose it in a crowded bike park or indeed a field with tall grass…

There’s also LED lighting throughout and, perhaps most impressively of all, an IMU is fitted enabling anti-tilt or cornering ABS on the front wheel. (This is the system found in the 2014 to 2016 Honda Fireblade and works well, too, although the rear brake, which isn’t part of the ABS system, is poor in comparison.)

The Monkey (and MSX) was also updated for 2021, gaining a revised, now-Euro5 compliant engine that actually gained a touch more power and a useful fifth gear.

While the Honda 125s’ popularity also means there’s a thriving aftermarket for accessories – particularly for the cult and longer established – Grom. But it's not unsual to see a Honda Monkey custom with twin exhausts, painted tank or frame and a tuned engine.

Model history & versions

Model history

Although the Monkey 125 was launched in 2018, the Monkey name has been around since the 1960s, starting in 1961 as an attraction for children at a Japanese theme park, complete with dinky five inch wheels and rigid suspension.

This then spawned a variety of other models, each sporting their own style and size. The first road-going classic Monkey arrived in 1963 and remained in Honda's line-up until 2009. Nine years later, it makes its return.

But what about the future? Well, a Honda Monkey electric hasn't been mooted, but it would be the ideal type of machine for such a powertrain.

Other versions

The Honda Monkey 125 is based on the similarly-sized Honda MSX125, or Grom as it's also known.

Using the same wheels, brakes and front suspension, the humble Grom has been with us since 2013 and, in that time, has recieved updates to make it Euro4 compliant.

Ideal fun bike for both learners and older riders. Not fast as 125 go but very forgiving. 110 % fun.

Ride quality & brakes 5 out of 5

Stops on a sixpence with good abs system. Big soft seat very comfortable. Easy suspension taking in the road bumps. Only let down would be no passenger pegs a one seat ride. Regular ride of 2 hours without issues arising refreshed and still with a smile on my face from the fun

Engine 5 out of 5

It's a 125 so no great speed but keeps up with main road traffic. Leaves cars stood at take off. Dual carriageway easy stuff. Not easy to overtake at any speed.

Reliability & build quality 5 out of 5

Only had the monkey 7 months and 2000 km so hard to find faults on reliability. But typical Honda build good quality parts. Paint finish and chrome superb. Starts first time every time no matter what the weather and storage.

Value vs rivals 5 out of 5

First service oil and fluids next to nothing.

Equipment 5 out of 5

You just have to switch it on and watch the Speedo light up it blinks and smiles at you. Same used on dax.

Buying experience: It was difficult to find one to buy, called 4 dealers before there was one in stock. Did find one and the dealer was superb great family history of bikes. Sales and service first rate.

Fun to ride. Easy to control. Would prefer tires capable of off road as well as on.

Ride quality & brakes 4 out of 5

Comfortable ride on a windless day.

Engine 3 out of 5

Underpowered. 5th gear is nice to have and is essentially an overdrive. Speed limits of 100km/hr are too much for this engine. 80 km/hr speed limits are within capability but just barely if hills are factored in. Should be a 150 cc or 175 cc engine to be truly capable.

Needs mirror extensions to be practical as rear visibility often blocked by rider’s body. Could use a standard rear luggage rack.

Very poor chrome quality: rear dampers, underside of front mudguard, mirror stalks all rusting after only few months normal careful use. Front mudguard idiotically placed: allows engine to become caked in road dirt. Unattractive convoluted exhaust system. Dealer PDI ( Hunts, Manchester) and customer service poor. Good parts: sweet to ride, comfortable, economical and fun. My advice? Try a Supercub125 instead.

Ride quality & brakes 4 out of 5

No pillion on a Monkey!!. Happily ride 50 mike stretches between breaks on crowded U K roads.

Engine 4 out of 5

Good range of power, and torque. Feels a little ‘strangled’ at top end: fuel injection programme?

Reliability & build quality 3 out of 5

Mechanically seems fine, but chrome very poor ( see above ) and detail final assembly questionable: air box loose, several screws slack.

Value vs rivals 3 out of 5

Service at home. Hunts declined to provide first ‘free’ service. Shouldn’t be more expensive than average.

Equipment 3 out of 5

Luggage rack unavailable when I purchased mine. Needs one. Seat is broad and comfortable.

Buying experience: Dealer: Hunts, Manchester.. Received small discount. No trade-in.

4 out of 5 Fun & frugal but potential gearbox issues.
25 August 2022 by Doug Hill

Year: 2022

Great fuel economy, goes around roundabouts faster than bigger bikes. Suspension perfect for poorly surfaced UK roads . Only gripe is the new 5 gear gearbox. No problems with selecting gear & finding neutral but OMG it really whines. In fact it's louder than the exhaust. There are plenty of sites making upmarket parts to customise your bike.

Ride quality & brakes 5 out of 5

No complaints, supple ride. mega comfy seat. Brakes OK but I don't think front powerful enough to activate ABS. Stock tyres are fine

Engine 3 out of 5

Don't expect much, its only 9hp. You will easily get burnt at lights by Deliveroo riders. max speed @ 55mph. 5 gears is an advantage over the old version BUT gearbox whine is dreadful. It has to be a design flaw that will get a recall at some point. Dropping down a gear reminds me of some 1950's straight cut gear box. 4th is also very noisy but 5th isn't for some reason. I wear earplugs & coast to a stop to avoid the noise.

Reliability & build quality 5 out of 5

No issues so far but only done 600 miles. Stock chain is poop & has already been replaced with an upmarket version. Oil filter is a good addition to the new engine rather than the old oil spinner.

Value vs rivals 5 out of 5

150mpg & £22 road tax :)

Equipment 3 out of 5

Great looks, park it anywhere. An aftermarket exhaust will improve the sound but will do little for performance (at great expense if a Yoshimura). Have added a fender extender to protect engine in winter & paddock stand bobbins to make chain adjustment easier.

Buying experience: Farnham Honda very good.

Bought this brand new in March 2022 and I cannot fault this motorcycle. This is despite what has been said about the dash or lack of it. I bought it after reading about it and watching a lot of YouTube videos on the 2018 model and the (then) few on the 2022 release. I did not test ride it before buying it and just love it to bits. If you get one be prepared for a lot of thumbs up, smiles and questions at traffic lights etc.; that's not a bad thing. This chimp is a keeper. Mine is in Glittering Blue Metallic and is called Blue Monkey (yeah not very original) Stop thinking about it and buy it now as a primary or second motorcycle, this is one cute Monkey.

4 out of 5 Monkey Z125 - 11,500 miles and still going strong!
18 July 2022 by Chamster*

Year: 2018

I have owned my Monkey for almost four years now and use it all year round as a commuter bike with nearly 12,000 miles on the clock. It's perfect for weaving through heavy city traffic or going for a blast (of sorts) on twisty country roads - just wind it up and keep the throttle pinned! It still turns heads and I often have conversations when stopped at traffic lights with various road users either enquiring about the engine capacity or reminiscing Monkeys of old. A joy to own and ride!

Ride quality & brakes 4 out of 5

The seat is like a giant marshmallow and extremely comfortable to ride. I have been on a few long ride outs and to be honest, it's usually the need for a drink or a comfort break that stops me.With ABS on the front, the brakes are generally good - they do the job so that's all that matters. I have always felt though that the back brake generally feels a little vague until you have to stamp on it.

Engine 5 out of 5

Typical Honda - the engine is great and just keeps going. I can generally reach/cruise at 55 mph when needed.

Reliability & build quality 4 out of 5

Despite being used all year round including many cold winters - it looks great! I use mine more than the average Monkey user so it's going to have a little wear and tear compared to most. Apart from the header pipe, it's only when you look really closely such as under the mudguards where you can find corrosion. I try to keep on top with occasional use of ACF50 but it doesn't seem to be a problem - the bike is solid! My only gripe with the Monkey is the chain which seems to have come off a BMX and therefore needs adjusting regularly. I always keep on top of cleaning it but I have been through two sprocket sets now and onto my third which luckily I can change myself.

Value vs rivals 5 out of 5

It is dirt cheap to run - even now it only costs me about £5 to fill up. I don't get the mileage other owners seem to get, probably 140 miles per tank but then again, I usually fill up before I get to the last bar. My daily ride is a mixture of city riding and stretches of dual-carriageway so this would have some impact. After the first three dealer services (about £100 each time) I maintain the bike myself now which helps keep costs down. Apart from replacement gaskets (which aren't always needed) and oil, the only cost is time because an oil change requires taking one side of the engine plate off and inspecting the oil screen and spinner. Pretty sure this is easier with newer Monkeys because Honda have fitted an inspection plate. The brakes and air filter have only recently needed changing.

Equipment 5 out of 5

The stock exhaust still has a nice throaty sound so I have never felt the need to change it. Tyres are fine in the dry but I have never felt as confident with them in the wet. I have my original front tyre and second rear tyre (still with plenty of tread) and think I'll be looking at other options when they need replacement sometime next year.

Buying experience: Purchased the bike from new at Suttons Honda Tamworth. Buying experience was good and they were always good at keeping me up to date. They are a good group of blokes and always look after you.

5 out of 5 The best things come in small packages
29 March 2021 by Phil Hes

Year: 2019

The Honda 125 Monkey Bike is great fun, built to a high standard and surprisingly comfortable. It handles like any other 125 but with a low seat height and being very lightweight, it is easy to ride and exceptionally nimble and manoeuvrable around town.

Ride quality & brakes 5 out of 5

The ride quality is very good and the seat is exceptionally comfortable. The bike has ABS, so breaking is quite reasonable. The smaller tyres just mean you have to be careful of pot holes but it generally rides like a regular bike.

Engine 5 out of 5

The engine is quite spritely, given its size and will get you away from traffic lights fairly swiftly. The four gears take a bit of getting used to and with no gear indicator, at first I was always trying to change up to an imaginary 5th gear. On faster roads it will sit comfortably at 55/60 mph but I wouldn’t like to take on a dual carriageway as it lacks power at higher speeds.

Reliability & build quality 5 out of 5

I have only had the bike a few months, so long term reliability is unknown but so far it hasn’t let me down. Starts first time, all the switches and gauges work fine and the bike has LED lights and indicators which help you to be seen. The bike feels premium and well made.

Value vs rivals 5 out of 5

The bike is very frugal and so far I’ve covered nearly 200 miles on £5 of fuel! Insurance is very cheap (but obviously this will depend on your age and where you live) and annual road tax is next to nothing (£20).

Equipment 4 out of 5

Equipment wise, the bike is quite basic but that is part of the attraction. It has a nice electronic gauge with speed, fuel and mileage easily readable and comes with ABS. It could benefit from a gear indicator though.

Buying experience: Bought pre-owned from Moonraker Motorcycles in Norwich who were excellent.

Suspension is suited to the lighter rider, consider upgrade if in the 85kg or higher category as the bike bottoms out to easily if you like the pies...
