Every technical detail, from suspension travel to tyre sizes, is covered in the full 2023 KTM 300 EXC SIXDAYS spec sheet below.

2023 KTM 300 EXC SIXDAYS compared with other bikes in the Enduro / Off-Road category

Measured against other bikes in the Enduro / Off-Road category in our database (up to 1434 models, one entry per model), the 2023 KTM 300 EXC SIXDAYS comes out as follows.

With 960 mm, the 300 EXC SIXDAYS has the joint 81st tallest seat height of 1146 bikes in the Enduro / Off-Road category, 9% above the category average of 879 mm.
Engine displacement of 293 cc is smaller than that of 871 of the other 1433 bikes in the Enduro / Off-Road category.
Narrowing the field to the 408 models within five model years of it, the seat height of 960 mm is taller than that of 360 of the other 407.

Versus the 2017 model

The figures we track are unchanged from the 2017 model: displacement and seat height all match.

2023 300 EXC SIXDAYS - Pros & Cons

Strengths

Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.

Considerations

Tall seat height: A 960 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
Modest fuel capacity: A 9-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling on the 300 EXC SIXDAYS comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Brake disc and pad wear

Single disc with Brembo 2-piston floating caliper up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by WP XPLOR-USD, Ø 48 mm up front and WP Xplor PDS shock absorber at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Chain final drive on the 300 EXC SIXDAYS means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Frame & chassis check

The Chrome-molybdenum steel central-tube frame chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Low-speed handling

The 300 EXC SIXDAYS's 103.9 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

300 EXC SIXDAYS - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2023 KTM 300 EXC SIXDAYS with its 293.2 cc enduro / off-road should cover the same ground every time: service history, drivetrain condition, and any oil seepage 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. Start it from cold if you can - a well-kept 300 EXC SIXDAYS settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the 300 EXC SIXDAYS's 293.2 cc single cylinder, two-stroke - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the 300 EXC SIXDAYS's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
