KTM 250 EXC: two-stroke enduro, TPI and what to check on a used one
KTM 250 EXC — a 250 cm³ two-stroke enduro motorcycle, prized for its lightness and agility. We look at how it differs from the 300 EXC and the four-stroke 250 EXC-F, what the TPI versions are like, and what to check on a used one.
250 EXC in brief
250 EXC — a lightweight two-stroke enduro motorcycle, suited to both challenging off-road trails and racing. Compared to the 300 EXC, it's considered more lively and easier to handle in technical terrain.
Be sure not to confuse the 250 EXC (two-stroke) with the 250 EXC-F — that's a four-stroke motorcycle with a completely different character and maintenance requirements.
Variants — how they differ
Earlier generations of the 250 EXC have a carburettor, while from 2018 onwards there's the TPI (Transfer Port Injection) version with fuel injection. The TPI variant doesn't require mixing oil with fuel.
When choosing between the 250 and 300 EXC, consider your riding style: the 250 EXC is more lively and lighter, while the 300 EXC has more low-end torque.
Engine and gearbox
The engine is a 250 cm³ two-stroke, liquid-cooled, single-cylinder, with an electric starter on newer models. It revs freely and is easy to manage.
The gearbox is manual, with multiple gears, and the clutch is cable-operated. Power is delivered to the rear wheel via a chain.
What to check when buying a used 250 EXC
Most importantly, check the engine hours and service history. Ask when the piston, rings, and connecting rod bearings were last changed, and if there are any bills for repairs.
Check the frame and suspension for cracks, steering rack and shock absorber mounts, subframe, timing chain, pulleys, wheel bearings, and the exhaust system. Before buying, start the engine and listen for any unusual noises.
