By now even pampered Kawasaki KMX125s will feel tired. And no-one pampers a Kawasaki KMX125. Head races will be squared, fork oil thin and the shock out of damping. Fortunately none of that’s too dear to sort. Once fettled the Kawasaki KMX125 can well handle on and off-road action (with the right tyres). If the brakes feel poor they probably just need a bleed and fresh pads, but if you're buying a Kawasaki KMX125 check the hoses for bulges and the discs for wear.
As bog stock the Kawasaki KMX125's two-stroke SOHC motor makes just 12bhp, though the KIPS induction valves means that the power is evenly spread and not tightly jammed at the top end. It’s important to keep these valves clean, but thankfully it’s a simple job (just remove the exhaust and cylinder head, dig out the valves and clean them with a wire brush). De-restricting the Kawasaki KMX125's motor involves removing a welded-in washer in the exhaust pipe and using a softer spring to let the KIPS actuator open fully.
The Kawasaki KMX125 isn’t fussy about which stroker oil you use, so long as you keep it topped up. New pistons and rings for the Kawasaki KMX125 are cheap (£25-30) and the motor’s good for going on for 50,000 miles, though de-restricted ones can be very unreliable.
