Boasting the latest in Honda’s ultra-compact, lightweight, 4-Stroke engines, Honda’s UMK425 Bike Handle Brushcutter pumps out superb power and more torque than ever before.

Powered by Honda’s new Generation II GX25 Mini 4-Stroke engine, the UMK425 is designed to deliver power that no 2-stroke competitor can match. Its ultra-compact, lightweight design means it’s easier to handle and will keep you working longer with less fatigue.

And as you’ve come to expect from Honda, the UMK425 Bike’s famous one pull easy-start system ensures it starts first time, every time.


Honda leads the world with revolutionary mini 4-Stroke engines that deliver more power and use less oil, and the UMK435 is a perfect example of Honda engineering at its best.

It uses unleaded fuel so you’ll never have to mix oil and fuel again, and it’s environmentally-friendly with low emissions, less noise and low fuel consumption compared to other Brushcutters.

With a 360° fully inclinable operation, a comfortable solid drive shaft and a unique anti-vibration engine mount, Honda’s quality extends to your comfort too.


The UMK425 Bike delivers excellent torque and performance via its Generation II, GX25 mini 4-Stroke engine.

It also features an ergonomically designed easy-grip bike handle, safety goggles & operator harness and the ability to operate across 360°, reducing the workload on your back and shoulders.

And on the ground, the UMK425 Bike makes tough jobs easy with a 4-tooth metal blade plus a heavy-duty tap-and-go nylon line head.


The UMK425 Bike, like all Honda’s brushcutters, comes with a standard 4-year Domestic Warranty, as well as a 3-year Commercial Engine Warranty and 12-month Commercial Frame Warranty.

With ten different Brushcutter accessories also available, including blades, tap-and-go heads and different trimmer lines, there’s an accessory for every environment.
