2023 KTM 300 EXC SIXDAYS Overview
For 2023, KTM offers the 300 EXC SIXDAYS as an enduro / off-road motorcycle with 293.2 cc on tap. The 2023 KTM 300 EXC SIXDAYS is built around a Single cylinder, two-stroke engine. Internally, bore and stroke are 72 x 72 mm. In everyday use, the 2023 300 EXC SIXDAYS tips the scales at 103.9 kg, carries a 9-litre fuel tank, offers a seat height of 960 mm and spans a 1482 mm wheelbase. That's roughly 94.9 kg lighter than the average enduro / off-road motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2023 KTM 300 EXC SIXDAYS spec sheet below.
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.
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. 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 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. 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 a 300 EXC SIXDAYS's engine - 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.
