Overview
Who would have bet, back in the sixties, that a mini toy designed to entertain visitors at a Honda amusement park would become a cult object six decades later? The Honda Monkey 125 motorcycle, 2025 version, returns with a handful of calibrated updates to clear the Euro5+ hurdle. New ignition, revised injection, OBD2 diagnostic port: nothing spectacular on paper, but enough to keep the monkey alive in an increasingly tight regulatory market.

Let's talk engine. The 124 cc single-cylinder, borrowed from the Grom family, features a 50 mm bore and a 63.1 mm stroke. This long-stroke character favors low-end torque, and the 12.7 Nm available from just 5,500 rpm confirms it. On the power side, 9.4 horsepower at 6,750 rpm won't scare anyone. The Honda Monkey 125 top speed caps out at 90 km/h, which is plenty to hold your own in suburban traffic without breaking a sweat. The five-speed gearbox, also inherited from the Grom, brings real cruising comfort that the older four-speed versions could never offer. On open roads, fifth gear relaxes the mechanicals and keeps the piston from churning like an egg beater. With a 5.6-liter tank and a claimed consumption under two liters per hundred kilometers, the theoretical range flirts with 300 kilometers. Not bad for a pocket-sized package.
And about that size — everything is miniature, and proudly so. 12-inch wheels, 104 kg wet weight, a seat perched 775 mm off the ground, and chrome everywhere: the Monkey doesn't try to pass for something it's not. It plays the pure fun card, guaranteed smiles included. The steel mono-backbone frame gets the job done without pretension, while the inverted fork and twin rear shocks offer 100 and 104 mm of travel respectively. That's short, but consistent with the urban riding and Sunday cruises that make up the beast's natural playground. The Nissin braking setup, with a 220 mm front disc and 190 mm rear, benefits from ABS paired with an IMU inertial unit that monitors rear wheel lift. On a machine this size, that level of equipment raises an eyebrow.
The Honda Monkey 125 price comes in at 4,449 euros, placing it in a sensitive zone against competitors like the Kawasaki Z125 or certain aggressively priced Chinese alternatives. Expensive for a single-cylinder 125? Yes, if you think strictly in terms of raw price-to-performance ratio. No, if you factor in Honda build quality, the solid resale value on the used Honda Monkey 125 market, and above all the emotional attachment this machine provokes. Honda Monkey 125 forums are brimming with enthusiasts who pile on Honda Monkey 125 accessories, from luggage racks to exhaust kits, turning their monkey into a one-of-a-kind object. The Honda Monkey 125 custom community is in fact one of the most active in the mini-bike segment, with builds that sometimes border on wildly creative.
This motorcycle isn't aimed at beginners looking for a versatile first 125, nor at riders in a hurry. It targets style enthusiasts and those who appreciate mechanical good vibes — people who want an offbeat second vehicle for grabbing bread or cruising along the coast on a Sunday morning. The Monkey 125 2025 revolutionizes nothing, claims to break nothing. It steadfastly carries on a recipe more than sixty years old, dusted with just the right amount of modern technology. And it's precisely that honesty that makes it endearing.
