2017 KTM 300 EXC Overview

The 2017 KTM 300 EXC is an enduro / off-road motorcycle built around 293 cc of displacement. Under the tank sits a Single cylinder, two-stroke engine. The bore and stroke measures 72 x 72 mm. From a practical standpoint, the 2017 300 EXC tips the scales at 100 kg, carries a 9.50-litre fuel tank, offers a seat height of 960 mm and spans a 1,482 mm wheelbase. That's roughly 98.8 kg lighter than the average enduro / off-road motorcycle in our database. Scroll down for the complete 2017 KTM 300 EXC spec sheet covering every technical detail from suspension travel to tyre sizes.

2017 300 EXC - Pros & Cons

Strengths

Factory engineering: The 2017 KTM 300 EXC represents KTM's engineering at the time, with a specification built around real-world usability.

Considerations

Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.
Tall seat height: The 960 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Modest fuel capacity: The 9.50-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Carburetor maintenance

The 300 EXC uses carburetion rather than fuel injection, which means jetting is altitude- and temperature-sensitive and benefits from a clean-and-rejet after extended storage or an exhaust change.

Brake disc and pad wear

The Single disc. Brake calipers on floating bearings front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the 300 EXC runs WP USD ? 48 mm and WP PDS shock absorber at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Chrome-molybdenum steel central-tube - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Low-speed handling

At just 100 kg, the 300 EXC is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

300 EXC - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2017 KTM 300 EXC, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained 300 EXC should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any 300 EXC. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the 300 EXC has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
