購入者が知っておくべきこと
KIPS valves need cleaning
The KIPS power valve system carbons up and can seize if the bike was run rich or on cheap oil, killing top-end pull. Budget for pulling the cylinder to clean the valves and check the actuator gears — it's a known service item, not a fault.
Cheap, simple rebuilds
These engines are famously tough but need a piston every 30-50 hours; kits and gaskets are inexpensive and widely available. Watch for worn cylinder plating, tired crank bearings (listen for bottom-end rattle) and leaking water pump/counter-balancer seals.
Bargain versus 2005-up
Because the aluminum-frame KX250 arrived in 2005, these steel-frame bikes sell for noticeably less — great value entry into a hard-hitting 250 two-stroke. Clean, titled, original examples have stopped depreciating and are slowly climbing as premix bikes gain collector interest.
