2026 Monkey 125 - Pros & Cons
Strengths
-
⚡
Strong power output: 2026 Honda Monkey 125 makes 9.2 hp @ 6750 rpm with 10.7 Nm @ 5500 rpm of torque - competitive figures for its class.
-
🔧
Fuel injection: The PGM-FI electronic fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Considerations
-
⛽
Modest fuel capacity: The 5.6-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
-
⚙️
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.
Wear Points & Servicing Notes
Heat management in traffic
Monkey 125's air-cooled design means engine-bay temperatures build up more in stop-start traffic than on a liquid-cooled equivalent - a function of the cooling method itself, not a defect. Mesh riding gear and avoiding prolonged idling help in hot climates.
Fuelling & injector care
Fuelling comes from PGM-FI electronic fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.
Brake disc and pad wear
The Single 220 mm hydraulic disc with IMU-based ABS front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the Monkey 125 runs Upside down telescopic forks and Dual shocks, swingarm at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.
Frame & chassis check
The frame is Steel backbone frame - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Low-speed handling
At just 105 kg, the Monkey 125 is light enough to manhandle easily at a standstill - one of the practical advantages of its class.
Monkey 125 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2026 Honda Monkey 125, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained Monkey 125 should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any Monkey 125. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The Monkey 125's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
