Lightweight Two-Stroke Trail Weapon
The WRE 125 is a small, honest two-stroke enduro. Its 124 cc liquid-cooled single makes 15 hp at 9,500 rpm and drives a chain through a 6-speed gearbox. Husqvarna put it in a steel double-cradle frame with an upside-down fork and a 21/18-inch wheel pair. It gets 10.2 in (260 mm) of travel up front, 10.7 in (272 mm) at the rear and 13.0 in (330 mm) of ground clearance. That is proper enduro hardware on a bike built as a way into off-road riding. It looks every bit the serious dirt bike, and it is light enough on its feet to forgive the mistakes a newer rider will make.
Ridden right, this is a bike you keep on the pipe. It lives in the mid-range, so the reward comes from working the gearbox, not from waiting for grunt that a 125 two-stroke doesn't have. By my enduro yardstick that's fine, because rideability counts for more than peak numbers. It is tough and easy to wrench on, which is exactly what a first dirt bike needs. The honest caveat is mechanical. Oil pump failures have wrecked engines at low mileage, so check the history of any used example. The fork isn't adjustable, the shock only takes preload, and the 37.2 in (944 mm) seat is tall.

Chassis
This picture comes from years of listening: talk in the paddock, owners comparing notes on club nights, and the messages riders send me directly. On the WRE 125 the story repeats itself. Owners love how eagerly the engine revs and how easily the bike moves. Their complaints are about the engine's temperament and what it takes to keep it healthy.
Riders consistently describe lively acceleration and a broad powerband. Several say the 2012 update sharpened response low in the rev range and through the middle. The low weight and nimble chassis come up just as often, and owners say the bike gives them confidence on technical trails. Not everyone agrees about the power. One owner found the stock engine flat below the power-valve opening point, where it struggled to pull cleanly.
A recurring complaint is that long road transfers wear riders out. Owners who have had an oil pump fail say it often meant a full engine rebuild. Others report rough idling and bogging at high revs, which they trace to the carburetor. A smaller number mention an 'ECU2' warning on the display that cuts power. They say it is hard to track down because some dealers don't have the diagnostic equipment for it.
Oil pump failure can destroy engine
Reports of oil pump failures leading to catastrophic engine damage, often occurring at relatively low mileage (e.g., 1800 km). Replacement of the pump, main bearings, crank, and piston may be required.
ECU2 error reduces power
The digital dash displays 'ECU2' accompanied by a temperature warning light and a noticeable drop in engine power. The fault may be related to the throttle position sensor or temperature sensor circuit.
Power valve misadjustment from factory
Many owners report that the exhaust power valve does not close fully when new, delaying the mid‑range torque transition and causing a bog or sudden hit. Re‑adjusting the valve linkage restores linear delivery.
Kick-start difficulties
Hard starting, requiring multiple kicks, especially after the bike has been running. Dirty carburettors, incorrect jetting, or clogged fuel lines are common culprits.
Clutch slippage under heavy use
Worn clutch plates lead to slippage and loss of acceleration; more frequent on bikes ridden aggressively in mud or deep sand. Replacement plates and cable adjustment resolve the issue.
Where this Husqvarna WRE 125 pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the WRE 125 is actually built for.
For technical desert day trips it makes sense: it's light, with 13.0 in of clearance and long travel. Just know that 15 hp takes commitment in deep sand, and the 2.5 gal tank keeps rides short.
Made for Moab · Bar M / Kane Creek · Imperial Sand Dunes
Honestly, this isn't your BDR bike. With 2.5 gal of fuel, no luggage system and 15 hp, multi-day routes are a stretch. Buy it to sharpen your dirt skills between trips.
Made for AZBDR — Arizona Backcountry Discovery Route · California BDR South · COBDR — Colorado Backcountry Discovery Route
If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
