2023 250 EXC SixDays - Pros & Cons

Strengths

Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
Strong front braking: Stopping power up front is strong thanks to the single disc setup, with plenty of room to upgrade further with braided lines.

Considerations

Tall seat height: At 960 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Modest fuel capacity: Range between stops is limited by the 9-litre tank - plan fuel stops accordingly on longer routes.
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.

Wear Points & Servicing Notes

Fuelling & injector care

The fuel injection on the 250 EXC SixDays needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Brake disc and pad wear

Braking up front comes from single disc with Brake calipers on floating bearings - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The 250 EXC SixDays's suspension runs WP XPLOR-USD, Ø 48 mm at the front. The rear uses WP Xplor PDS shock absorber. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The 250 EXC SixDays uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.

Frame & chassis check

Built around a Central double-cradle-type 25CrMo4 steel, the 250 EXC SixDays's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Low-speed handling

103.4 kg keeps the 250 EXC SixDays easy to move around in tight spaces, car parks and on the stand alike.

250 EXC SixDays - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2023 KTM 250 EXC SixDays with its 249 cc enduro / off-road, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 3 years old, this enduro / off-road is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy 250 EXC SixDays should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects the 250 EXC SixDays's 249 cc single cylinder, two-stroke like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.

Fuel system care

Fuel injection on the 250 EXC SixDays needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
